We look at the division of 87705260 by 629 
The aim is to understand the frequency of 629 in 87705260.

Moving on to step 1:
The number 629 fits into 8 0 times, leaving a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Include the next digit (7) from the dividend after 8, then repeat: 87 / 629

Advancing to step 2:
If we divide 87 by 629, we get 0 and a remainder of 87.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 87, we end up with 87.
Include the next digit (7) from the dividend after 87, then repeat: 877 / 629

Going ahead to step 3:
629 goes into 877 1 times with a remainder of 248.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Deduct 629 from 877 and we're left with 248.
Include the next digit (0) from the dividend after 248, then repeat: 2480 / 629

On to step 4:
When dividing 2480 by 629, we get 3 with a remainder of 593.
Record the quotient 3 as the next digit in the result. 
Result so far: 13.0
If we subtract 1887 from 2480, we get 593.
Bring next digit (5) of the dividend behind the 593 and repeat the process: 5935 / 629

Advancing to step 5:
629 goes into 5935 9 times with a remainder of 274.
The next digit of our result is 9. 
Result so far: 139.0
If we take 5661 away from 5935, we end up with 274.
Fetch the next digit (2) from the dividend, attach it to 274 and continue: 2742 / 629

Moving on to step 6:
When dividing 2742 by 629, we get 4 with a remainder of 226.
Use 4 as the next digit of our solution. 
Result so far: 1394.0
Subtract 2516 from 2742 to get 226.
Include the next digit (6) from the dividend after 226, then repeat: 2266 / 629

Advancing to step 7:
When dividing 2266 by 629, we get 3 with a remainder of 379.
Record the quotient 3 as the next digit in the result. 
Result so far: 13943.0
The remainder is 379 after subtracting 1887 from 2266.
Include the next digit (0) from the dividend after 379, then repeat: 3790 / 629

On to step 8:
The number 629 fits into 3790 6 times, leaving a remainder of 16.
Record the quotient 6 as the next digit in the result. 
Result so far: 139436.0
Deduct 3774 from 3790 and we're left with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Advancing to step 9:
When dividing 160 by 629, we get 0 with a remainder of 160.
The next digit of our result is 0. 
Result so far: 139436.0
Subtract 0 from 160 to get 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Moving on to step 10:
The number 629 fits into 1600 2 times, leaving a remainder of 342.
The next digit of our result is 2. 
Result so far: 139436.02
Subtracting 1258 from 1600 leaves us with 342.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3420, and continue the process.

Step 11:
629 goes into 3420 5 times with a remainder of 275.
Write down 5 as next digit of the result. 
Result so far: 139436.025
If we take 3145 away from 3420, we end up with 275.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2750, and continue the process.

On to step 12:
If we divide 2750 by 629, we get 4 and a remainder of 234.
Use 4 as the next digit of our solution. 
Result so far: 139436.0254
The remainder is 234 after subtracting 2516 from 2750.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2340, and continue the process.

Going ahead to step 13:
629 goes into 2340 3 times with a remainder of 453.
Record the quotient 3 as the next digit in the result. 
Result so far: 139436.02543
Subtracting 1887 from 2340 leaves us with 453.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4530, and continue the process.

Advancing to step 14:
629 goes into 4530 7 times with a remainder of 127.
The number 7 becomes the next digit in our result. 
Result so far: 139436.025437
If we take 4403 away from 4530, we end up with 127.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1270, and continue the process.

On to step 15:
When dividing 1270 by 629, we get 2 with a remainder of 12.
Record the quotient 2 as the next digit in the result. 
Result so far: 139436.0254372
If we subtract 1258 from 1270, we get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Going ahead to step 16:
120 divided by 629 is 0 with a remainder of 120.
Put 0 as the next digit of the answer. 
Result so far: 139436.0254372
If we subtract 0 from 120, we get 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

The final result is 139436.0254372 with a remainder of 1.2e-07.
