We look at the division of 59769494 by 646 
The aim is to understand the frequency of 646 in 59769494.

Let's proceed to step 1:
5 divided by 646 is 0 with a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Bring next digit (9) of the dividend behind the 5 and repeat the process: 59 / 646

Advancing to step 2:
If we divide 59 by 646, we get 0 and a remainder of 59.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 59 to get 59.
Include the next digit (7) from the dividend after 59, then repeat: 597 / 646

Going ahead to step 3:
646 can be fit into 597 0 times, resulting in a remainder of 597.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 597 and we're left with 597.
Fetch the next digit (6) from the dividend, attach it to 597 and continue: 5976 / 646

Moving on to step 4:
The number 646 fits into 5976 9 times, leaving a remainder of 162.
The number 9 becomes the next digit in our result. 
Result so far: 9.0
The remainder is 162 after subtracting 5814 from 5976.
Bring next digit (9) of the dividend behind the 162 and repeat the process: 1629 / 646

On to step 5:
When dividing 1629 by 646, we get 2 with a remainder of 337.
The number 2 becomes the next digit in our result. 
Result so far: 92.0
The remainder is 337 after subtracting 1292 from 1629.
Append the next digit (4) from the dividend to 337 and continue with: 3374 / 646

Advancing to step 6:
3374 divided by 646 is 5 with a remainder of 144.
Put 5 as the next digit of the answer. 
Result so far: 925.0
Subtract 3230 from 3374 to get 144.
Append the next digit (9) from the dividend to 144 and continue with: 1449 / 646

Let's proceed to step 7:
When dividing 1449 by 646, we get 2 with a remainder of 157.
Use 2 as the next digit of our solution. 
Result so far: 9252.0
If we subtract 1292 from 1449, we get 157.
Take the next digit (4) from the dividend and append it to 157, then repeat: 1574 / 646

On to step 8:
When dividing 1574 by 646, we get 2 with a remainder of 282.
Record the quotient 2 as the next digit in the result. 
Result so far: 92522.0
If we take 1292 away from 1574, we end up with 282.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2820, and continue the process.

On to step 9:
646 goes into 2820 4 times with a remainder of 236.
The number 4 becomes the next digit in our result. 
Result so far: 92522.4
If we take 2584 away from 2820, we end up with 236.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2360, and continue the process.

Going ahead to step 10:
646 can be fit into 2360 3 times, resulting in a remainder of 422.
The number 3 becomes the next digit in our result. 
Result so far: 92522.43
If we take 1938 away from 2360, we end up with 422.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4220, and continue the process.

Going ahead to step 11:
The number 646 fits into 4220 6 times, leaving a remainder of 344.
Write down 6 as next digit of the result. 
Result so far: 92522.436
Deduct 3876 from 4220 and we're left with 344.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3440, and continue the process.

Let's proceed to step 12:
The number 646 fits into 3440 5 times, leaving a remainder of 210.
Record the quotient 5 as the next digit in the result. 
Result so far: 92522.4365
If we subtract 3230 from 3440, we get 210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2100, and continue the process.

Going ahead to step 13:
The number 646 fits into 2100 3 times, leaving a remainder of 162.
The number 3 becomes the next digit in our result. 
Result so far: 92522.43653
The remainder is 162 after subtracting 1938 from 2100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1620, and continue the process.

Going ahead to step 14:
The number 646 fits into 1620 2 times, leaving a remainder of 328.
Use 2 as the next digit of our solution. 
Result so far: 92522.436532
If we subtract 1292 from 1620, we get 328.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3280, and continue the process.

Let's proceed to step 15:
If we divide 3280 by 646, we get 5 and a remainder of 50.
The next digit of our result is 5. 
Result so far: 92522.4365325
The remainder is 50 after subtracting 3230 from 3280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Let's proceed to step 16:
If we divide 500 by 646, we get 0 and a remainder of 500.
Write down 0 as next digit of the result. 
Result so far: 92522.4365325
If we take 0 away from 500, we end up with 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5000, and continue the process.

The final result is 92522.4365325 with a remainder of 5e-07.
