Let's divide 44915787 by 646
The aim is to understand the frequency of 646 in 44915787.

Moving on to step 1:
646 goes into 4 0 times with a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Bring next digit (4) of the dividend behind the 4 and repeat the process: 44 / 646

Advancing to step 2:
When dividing 44 by 646, we get 0 with a remainder of 44.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 44 and we're left with 44.
Include the next digit (9) from the dividend after 44, then repeat: 449 / 646

Step 3:
If we divide 449 by 646, we get 0 and a remainder of 449.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 449, we end up with 449.
Append the next digit (1) from the dividend to 449 and continue with: 4491 / 646

Step 4:
When dividing 4491 by 646, we get 6 with a remainder of 615.
Use 6 as the next digit of our solution. 
Result so far: 6.0
If we subtract 3876 from 4491, we get 615.
Take the next digit (5) from the dividend and append it to 615, then repeat: 6155 / 646

Let's proceed to step 5:
When dividing 6155 by 646, we get 9 with a remainder of 341.
Use 9 as the next digit of our solution. 
Result so far: 69.0
The remainder is 341 after subtracting 5814 from 6155.
Grab the next digit (7) from the dividend, add it to 341, then carry on: 3417 / 646

Let's proceed to step 6:
If we divide 3417 by 646, we get 5 and a remainder of 187.
Record the quotient 5 as the next digit in the result. 
Result so far: 695.0
Deduct 3230 from 3417 and we're left with 187.
Include the next digit (8) from the dividend after 187, then repeat: 1878 / 646

Let's proceed to step 7:
When dividing 1878 by 646, we get 2 with a remainder of 586.
Put 2 as the next digit of the answer. 
Result so far: 6952.0
If we subtract 1292 from 1878, we get 586.
Fetch the next digit (7) from the dividend, attach it to 586 and continue: 5867 / 646

Advancing to step 8:
646 goes into 5867 9 times with a remainder of 53.
The number 9 becomes the next digit in our result. 
Result so far: 69529.0
Subtracting 5814 from 5867 leaves us with 53.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

Step 9:
646 can be fit into 530 0 times, resulting in a remainder of 530.
The number 0 becomes the next digit in our result. 
Result so far: 69529.0
Subtract 0 from 530 to get 530.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5300, and continue the process.

Going ahead to step 10:
5300 divided by 646 is 8 with a remainder of 132.
Use 8 as the next digit of our solution. 
Result so far: 69529.08
If we take 5168 away from 5300, we end up with 132.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1320, and continue the process.

Advancing to step 11:
646 can be fit into 1320 2 times, resulting in a remainder of 28.
Put 2 as the next digit of the answer. 
Result so far: 69529.082
Subtracting 1292 from 1320 leaves us with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Advancing to step 12:
646 goes into 280 0 times with a remainder of 280.
The number 0 becomes the next digit in our result. 
Result so far: 69529.082
Subtract 0 from 280 to get 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

On to step 13:
The number 646 fits into 2800 4 times, leaving a remainder of 216.
Put 4 as the next digit of the answer. 
Result so far: 69529.08204
Deduct 2584 from 2800 and we're left with 216.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2160, and continue the process.

Going ahead to step 14:
The number 646 fits into 2160 3 times, leaving a remainder of 222.
Write down 3 as next digit of the result. 
Result so far: 69529.082043
If we take 1938 away from 2160, we end up with 222.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2220, and continue the process.

On to step 15:
If we divide 2220 by 646, we get 3 and a remainder of 282.
Put 3 as the next digit of the answer. 
Result so far: 69529.0820433
Deduct 1938 from 2220 and we're left 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.

After the division, we end up with 69529.0820433 and a remainder of 2.82e-06.
