Let's divide 735636 by 87
The aim is to understand the frequency of 87 in 735636.

Advancing to step 1:
7 divided by 87 is 0 with a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Fetch the next digit (3) from the dividend, attach it to 7 and continue: 73 / 87

Advancing to step 2:
When dividing 73 by 87, we get 0 with a remainder of 73.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 73, we end up with 73.
Append the next digit (5) from the dividend to 73 and continue with: 735 / 87

Let's proceed to step 3:
735 divided by 87 is 8 with a remainder of 39.
Write down 8 as next digit of the result. 
Result so far: 8.0
If we take 696 away from 735, we end up with 39.
Include the next digit (6) from the dividend after 39, then repeat: 396 / 87

Moving on to step 4:
87 goes into 396 4 times with a remainder of 48.
The number 4 becomes the next digit in our result. 
Result so far: 84.0
If we subtract 348 from 396, we get 48.
Grab the next digit (3) from the dividend, add it to 48, then carry on: 483 / 87

Moving on to step 5:
The number 87 fits into 483 5 times, leaving a remainder of 48.
Write down 5 as next digit of the result. 
Result so far: 845.0
If we subtract 435 from 483, we get 48.
Bring next digit (6) of the dividend behind the 48 and repeat the process: 486 / 87

Advancing to step 6:
87 can be fit into 486 5 times, resulting in a remainder of 51.
Use 5 as the next digit of our solution. 
Result so far: 8455.0
Deduct 435 from 486 and we're left with 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

Let's proceed to step 7:
When dividing 510 by 87, we get 5 with a remainder of 75.
Put 5 as the next digit of the answer. 
Result so far: 8455.5
If we subtract 435 from 510, we get 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Moving on to step 8:
The number 87 fits into 750 8 times, leaving a remainder of 54.
The next digit of our result is 8. 
Result so far: 8455.58
Deduct 696 from 750 and we're left with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Step 9:
When dividing 540 by 87, we get 6 with a remainder of 18.
The next digit of our result is 6. 
Result so far: 8455.586
Subtracting 522 from 540 leaves us with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Advancing to step 10:
When dividing 180 by 87, we get 2 with a remainder of 6.
The next digit of our result is 2. 
Result so far: 8455.5862
Deduct 174 from 180 and we're left with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Moving on to step 11:
The number 87 fits into 60 0 times, leaving a remainder of 60.
The number 0 becomes the next digit in our result. 
Result so far: 8455.5862
Subtract 0 from 60 to get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

On to step 12:
87 can be fit into 600 6 times, resulting in a remainder of 78.
Put 6 as the next digit of the answer. 
Result so far: 8455.586206
Subtracting 522 from 600 leaves us with 78.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

On to step 13:
The number 87 fits into 780 8 times, leaving a remainder of 84.
The next digit of our result is 8. 
Result so far: 8455.5862068
Subtract 696 from 780 to get 84.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

On to step 14:
87 goes into 840 9 times with a remainder of 57.
Record the quotient 9 as the next digit in the result. 
Result so far: 8455.58620689
If we take 783 away from 840, we end up with 57.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

The final result is 8455.58620689 with a remainder of 5.7e-08.
