90243162 divided by 687 
We want to figure out the number of times 90243162 can be divided by 687.

Advancing to step 1:
687 can be fit into 9 0 times, resulting in a remainder of 9.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 9 leaves us with 9.
Include the next digit (0) from the dividend after 9, then repeat: 90 / 687

On to step 2:
687 goes into 90 0 times with a remainder of 90.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 90, we end up with 90.
Fetch the next digit (2) from the dividend, attach it to 90 and continue: 902 / 687

On to step 3:
The number 687 fits into 902 1 times, leaving a remainder of 215.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtract 687 from 902 to get 215.
Grab the next digit (4) from the dividend, add it to 215, then carry on: 2154 / 687

Advancing to step 4:
If we divide 2154 by 687, we get 3 and a remainder of 93.
Record the quotient 3 as the next digit in the result. 
Result so far: 13.0
If we take 2061 away from 2154, we end up with 93.
Append the next digit (3) from the dividend to 93 and continue with: 933 / 687

On to step 5:
If we divide 933 by 687, we get 1 and a remainder of 246.
Record the quotient 1 as the next digit in the result. 
Result so far: 131.0
Subtract 687 from 933 to get 246.
Append the next digit (1) from the dividend to 246 and continue with: 2461 / 687

Moving on to step 6:
If we divide 2461 by 687, we get 3 and a remainder of 400.
Record the quotient 3 as the next digit in the result. 
Result so far: 1313.0
Subtract 2061 from 2461 to get 400.
Grab the next digit (6) from the dividend, add it to 400, then carry on: 4006 / 687

Step 7:
The number 687 fits into 4006 5 times, leaving a remainder of 571.
Write down 5 as next digit of the result. 
Result so far: 13135.0
Subtract 3435 from 4006 to get 571.
Include the next digit (2) from the dividend after 571, then repeat: 5712 / 687

Let's proceed to step 8:
The number 687 fits into 5712 8 times, leaving a remainder of 216.
Record the quotient 8 as the next digit in the result. 
Result so far: 131358.0
Subtracting 5496 from 5712 leaves us with 216.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2160, and continue the process.

Going ahead to step 9:
687 can be fit into 2160 3 times, resulting in a remainder of 99.
Use 3 as the next digit of our solution. 
Result so far: 131358.3
If we take 2061 away from 2160, we end up with 99.
Since there are no more digits in the dividend, we add a zero to the remainder making it 990, and continue the process.

Advancing to step 10:
When dividing 990 by 687, we get 1 with a remainder of 303.
Use 1 as the next digit of our solution. 
Result so far: 131358.31
Deduct 687 from 990 and we're left with 303.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3030, and continue the process.

Moving on to step 11:
If we divide 3030 by 687, we get 4 and a remainder of 282.
Put 4 as the next digit of the answer. 
Result so far: 131358.314
The remainder is 282 after subtracting 2748 from 3030.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2820, and continue the process.

Going ahead to step 12:
2820 divided by 687 is 4 with a remainder of 72.
Record the quotient 4 as the next digit in the result. 
Result so far: 131358.3144
If we subtract 2748 from 2820, we get 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Our division results in 131358.3144 with a remaining 0.00072.
