736903 ÷ 87 
The aim is to understand the frequency of 87 in 736903.

Step 1:
87 can be fit into 7 0 times, resulting in a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Grab the next digit (3) from the dividend, add it to 7, then carry on: 73 / 87

Step 2:
73 divided by 87 is 0 with a remainder of 73.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 73, we get 73.
Bring next digit (6) of the dividend behind the 73 and repeat the process: 736 / 87

Let's proceed to step 3:
87 can be fit into 736 8 times, resulting in a remainder of 40.
Use 8 as the next digit of our solution. 
Result so far: 8.0
Subtract 696 from 736 to get 40.
Take the next digit (9) from the dividend and append it to 40, then repeat: 409 / 87

Advancing to step 4:
If we divide 409 by 87, we get 4 and a remainder of 61.
Record the quotient 4 as the next digit in the result. 
Result so far: 84.0
If we subtract 348 from 409, we get 61.
Include the next digit (0) from the dividend after 61, then repeat: 610 / 87

Moving on to step 5:
The number 87 fits into 610 7 times, leaving a remainder of 1.
The number 7 becomes the next digit in our result. 
Result so far: 847.0
If we take 609 away from 610, we end up with 1.
Take the next digit (3) from the dividend and append it to 1, then repeat: 13 / 87

Step 6:
If we divide 13 by 87, we get 0 and a remainder of 13.
Write down 0 as next digit of the result. 
Result so far: 8470.0
Deduct 0 from 13 and we're left with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Going ahead to step 7:
If we divide 130 by 87, we get 1 and a remainder of 43.
Record the quotient 1 as the next digit in the result. 
Result so far: 8470.1
Deduct 87 from 130 and we're left with 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Advancing to step 8:
If we divide 430 by 87, we get 4 and a remainder of 82.
Use 4 as the next digit of our solution. 
Result so far: 8470.14
The remainder is 82 after subtracting 348 from 430.
Since there are no more digits in the dividend, we add a zero to the remainder making it 820, and continue the process.

On to step 9:
820 divided by 87 is 9 with a remainder of 37.
Write down 9 as next digit of the result. 
Result so far: 8470.149
The remainder is 37 after subtracting 783 from 820.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Going ahead to step 10:
87 goes into 370 4 times with a remainder of 22.
Put 4 as the next digit of the answer. 
Result so far: 8470.1494
Subtracting 348 from 370 leaves us with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Step 11:
The number 87 fits into 220 2 times, leaving a remainder of 46.
Record the quotient 2 as the next digit in the result. 
Result so far: 8470.14942
The remainder is 46 after subtracting 174 from 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Advancing to step 12:
If we divide 460 by 87, we get 5 and a remainder of 25.
Put 5 as the next digit of the answer. 
Result so far: 8470.149425
Subtracting 435 from 460 leaves us with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Step 13:
250 divided by 87 is 2 with a remainder of 76.
The next digit of our result is 2. 
Result so far: 8470.1494252
Deduct 174 from 250 and we're left with 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

On to step 14:
If we divide 760 by 87, we get 8 and a remainder of 64.
Record the quotient 8 as the next digit in the result. 
Result so far: 8470.14942528
If we subtract 696 from 760, we get 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Our division results in 8470.14942528 with a remaining 6.4e-08.
