We look at the division of 629594 by 87 
The aim is to understand the frequency of 87 in 629594.

Going ahead to step 1:
6 divided by 87 is 0 with a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Include the next digit (2) from the dividend after 6, then repeat: 62 / 87

Let's proceed to step 2:
The number 87 fits into 62 0 times, leaving a remainder of 62.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 62, we end up with 62.
Bring next digit (9) of the dividend behind the 62 and repeat the process: 629 / 87

Let's proceed to step 3:
87 goes into 629 7 times with a remainder of 20.
Write down 7 as next digit of the result. 
Result so far: 7.0
The remainder is 20 after subtracting 609 from 629.
Grab the next digit (5) from the dividend, add it to 20, then carry on: 205 / 87

On to step 4:
87 can be fit into 205 2 times, resulting in a remainder of 31.
Write down 2 as next digit of the result. 
Result so far: 72.0
If we take 174 away from 205, we end up with 31.
Append the next digit (9) from the dividend to 31 and continue with: 319 / 87

Let's proceed to step 5:
87 can be fit into 319 3 times, resulting in a remainder of 58.
The next digit of our result is 3. 
Result so far: 723.0
Deduct 261 from 319 and we're left with 58.
Fetch the next digit (4) from the dividend, attach it to 58 and continue: 584 / 87

Going ahead to step 6:
87 can be fit into 584 6 times, resulting in a remainder of 62.
Write down 6 as next digit of the result. 
Result so far: 7236.0
If we subtract 522 from 584, we get 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Let's proceed to step 7:
The number 87 fits into 620 7 times, leaving a remainder of 11.
The next digit of our result is 7. 
Result so far: 7236.7
The remainder is 11 after subtracting 609 from 620.
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 8:
If we divide 110 by 87, we get 1 and a remainder of 23.
Write down 1 as next digit of the result. 
Result so far: 7236.71
The remainder is 23 after subtracting 87 from 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Step 9:
230 divided by 87 is 2 with a remainder of 56.
Put 2 as the next digit of the answer. 
Result so far: 7236.712
Subtracting 174 from 230 leaves us with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Advancing to step 10:
If we divide 560 by 87, we get 6 and a remainder of 38.
Use 6 as the next digit of our solution. 
Result so far: 7236.7126
The remainder is 38 after subtracting 522 from 560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Step 11:
If we divide 380 by 87, we get 4 and a remainder of 32.
Write down 4 as next digit of the result. 
Result so far: 7236.71264
If we take 348 away from 380, we end up with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Advancing to step 12:
320 divided by 87 is 3 with a remainder of 59.
Write down 3 as next digit of the result. 
Result so far: 7236.712643
Subtract 261 from 320 to get 59.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

On to step 13:
87 goes into 590 6 times with a remainder of 68.
Write down 6 as next digit of the result. 
Result so far: 7236.7126436
Subtract 522 from 590 to get 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Let's proceed to step 14:
The number 87 fits into 680 7 times, leaving a remainder of 71.
Write down 7 as next digit of the result. 
Result so far: 7236.71264367
Subtract 609 from 680 to get 71.
Since there are no more digits in the dividend, we add a zero to the remainder making it 710, and continue the process.

The quotient of the division is 7236.71264367, and the remainder is 7.1e-08.
