We're dividing 643466 by 37 
The aim is to understand the frequency of 37 in 643466.

Advancing to step 1:
37 goes into 6 0 times with a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Fetch the next digit (4) from the dividend, attach it to 6 and continue: 64 / 37

Let's proceed to step 2:
37 can be fit into 64 1 times, resulting in a remainder of 27.
Use 1 as the next digit of our solution. 
Result so far: 1.0
The remainder is 27 after subtracting 37 from 64.
Bring next digit (3) of the dividend behind the 27 and repeat the process: 273 / 37

On to step 3:
The number 37 fits into 273 7 times, leaving a remainder of 14.
The next digit of our result is 7. 
Result so far: 17.0
If we take 259 away from 273, we end up with 14.
Append the next digit (4) from the dividend to 14 and continue with: 144 / 37

Moving on to step 4:
When dividing 144 by 37, we get 3 with a remainder of 33.
Use 3 as the next digit of our solution. 
Result so far: 173.0
Subtract 111 from 144 to get 33.
Take the next digit (6) from the dividend and append it to 33, then repeat: 336 / 37

Going ahead to step 5:
336 divided by 37 is 9 with a remainder of 3.
Put 9 as the next digit of the answer. 
Result so far: 1739.0
Subtract 333 from 336 to get 3.
Take the next digit (6) from the dividend and append it to 3, then repeat: 36 / 37

Going ahead to step 6:
36 divided by 37 is 0 with a remainder of 36.
Put 0 as the next digit of the answer. 
Result so far: 17390.0
If we subtract 0 from 36, we get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Let's proceed to step 7:
The number 37 fits into 360 9 times, leaving a remainder of 27.
The next digit of our result is 9. 
Result so far: 17390.9
If we take 333 away from 360, we end up with 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Going ahead to step 8:
The number 37 fits into 270 7 times, leaving a remainder of 11.
Put 7 as the next digit of the answer. 
Result so far: 17390.97
If we subtract 259 from 270, we get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Advancing to step 9:
The number 37 fits into 110 2 times, leaving a remainder of 36.
Put 2 as the next digit of the answer. 
Result so far: 17390.972
Deduct 74 from 110 and we're left with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Advancing to step 10:
When dividing 360 by 37, we get 9 with a remainder of 27.
Write down 9 as next digit of the result. 
Result so far: 17390.9729
Subtracting 333 from 360 leaves us with 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Step 11:
When dividing 270 by 37, we get 7 with a remainder of 11.
Write down 7 as next digit of the result. 
Result so far: 17390.97297
If we subtract 259 from 270, we get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Moving on to step 12:
The number 37 fits into 110 2 times, leaving a remainder of 36.
Use 2 as the next digit of our solution. 
Result so far: 17390.972972
Subtract 74 from 110 to get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Advancing to step 13:
37 goes into 360 9 times with a remainder of 27.
Write down 9 as next digit of the result. 
Result so far: 17390.9729729
Subtracting 333 from 360 leaves us with 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Let's proceed to step 14:
37 can be fit into 270 7 times, resulting in a remainder of 11.
Record the quotient 7 as the next digit in the result. 
Result so far: 17390.97297297
If we take 259 away from 270, we end up with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

After the division, we end up with 17390.97297297 and a remainder of 1.1e-08.
