We divide 39129787 by 637
The aim is to understand the frequency of 637 in 39129787.

Moving on to step 1:
637 can be fit into 3 0 times, resulting in a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Grab the next digit (9) from the dividend, add it to 3, then carry on: 39 / 637

Let's proceed to step 2:
637 goes into 39 0 times with a remainder of 39.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 39 after subtracting 0 from 39.
Fetch the next digit (1) from the dividend, attach it to 39 and continue: 391 / 637

Let's proceed to step 3:
The number 637 fits into 391 0 times, leaving a remainder of 391.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 391, we end up with 391.
Bring next digit (2) of the dividend behind the 391 and repeat the process: 3912 / 637

Moving on to step 4:
When dividing 3912 by 637, we get 6 with a remainder of 90.
The number 6 becomes the next digit in our result. 
Result so far: 6.0
Deduct 3822 from 3912 and we're left with 90.
Bring next digit (9) of the dividend behind the 90 and repeat the process: 909 / 637

Let's proceed to step 5:
637 can be fit into 909 1 times, resulting in a remainder of 272.
Use 1 as the next digit of our solution. 
Result so far: 61.0
Deduct 637 from 909 and we're left with 272.
Grab the next digit (7) from the dividend, add it to 272, then carry on: 2727 / 637

Going ahead to step 6:
When dividing 2727 by 637, we get 4 with a remainder of 179.
The number 4 becomes the next digit in our result. 
Result so far: 614.0
If we subtract 2548 from 2727, we get 179.
Grab the next digit (8) from the dividend, add it to 179, then carry on: 1798 / 637

Advancing to step 7:
If we divide 1798 by 637, we get 2 and a remainder of 524.
The next digit of our result is 2. 
Result so far: 6142.0
The remainder is 524 after subtracting 1274 from 1798.
Grab the next digit (7) from the dividend, add it to 524, then carry on: 5247 / 637

Let's proceed to step 8:
The number 637 fits into 5247 8 times, leaving a remainder of 151.
Write down 8 as next digit of the result. 
Result so far: 61428.0
The remainder is 151 after subtracting 5096 from 5247.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1510, and continue the process.

Going ahead to step 9:
If we divide 1510 by 637, we get 2 and a remainder of 236.
Use 2 as the next digit of our solution. 
Result so far: 61428.2
Deduct 1274 from 1510 and we're left 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.

Step 10:
When dividing 2360 by 637, we get 3 with a remainder of 449.
Use 3 as the next digit of our solution. 
Result so far: 61428.23
If we subtract 1911 from 2360, we get 449.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4490, and continue the process.

On to step 11:
637 goes into 4490 7 times with a remainder of 31.
The number 7 becomes the next digit in our result. 
Result so far: 61428.237
If we subtract 4459 from 4490, we get 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Moving on to step 12:
637 goes into 310 0 times with a remainder of 310.
Write down 0 as next digit of the result. 
Result so far: 61428.237
If we take 0 away from 310, we end up with 310.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3100, and continue the process.

Moving on to step 13:
If we divide 3100 by 637, we get 4 and a remainder of 552.
Use 4 as the next digit of our solution. 
Result so far: 61428.23704
Subtracting 2548 from 3100 leaves us with 552.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5520, and continue the process.

Going ahead to step 14:
637 can be fit into 5520 8 times, resulting in a remainder of 424.
The number 8 becomes the next digit in our result. 
Result so far: 61428.237048
If we subtract 5096 from 5520, we get 424.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4240, and continue the process.

Let's proceed to step 15:
4240 divided by 637 is 6 with a remainder of 418.
The next digit of our result is 6. 
Result so far: 61428.2370486
Subtracting 3822 from 4240 leaves us with 418.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4180, and continue the process.

Let's proceed to step 16:
637 goes into 4180 6 times with a remainder of 358.
The number 6 becomes the next digit in our result. 
Result so far: 61428.23704866
If we take 3822 away from 4180, we end up with 358.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3580, and continue the process.

The final outcome is 61428.23704866, with a leftover of 3.58e-07.
