87020666 divided by 403 
Our goal is to divide 87020666 by 403.

Going ahead to step 1:
If we divide 8 by 403, we get 0 and a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Bring next digit (7) of the dividend behind the 8 and repeat the process: 87 / 403

Let's proceed to step 2:
When dividing 87 by 403, we get 0 with a remainder of 87.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 87 leaves us with 87.
Include the next digit (0) from the dividend after 87, then repeat: 870 / 403

Let's proceed to step 3:
870 divided by 403 is 2 with a remainder of 64.
Write down 2 as next digit of the result. 
Result so far: 2.0
Deduct 806 from 870 and we're left with 64.
Include the next digit (2) from the dividend after 64, then repeat: 642 / 403

Going ahead to step 4:
The number 403 fits into 642 1 times, leaving a remainder of 239.
Put 1 as the next digit of the answer. 
Result so far: 21.0
Subtracting 403 from 642 leaves us with 239.
Grab the next digit (0) from the dividend, add it to 239, then carry on: 2390 / 403

Step 5:
When dividing 2390 by 403, we get 5 with a remainder of 375.
Use 5 as the next digit of our solution. 
Result so far: 215.0
The remainder is 375 after subtracting 2015 from 2390.
Take the next digit (6) from the dividend and append it to 375, then repeat: 3756 / 403

Moving on to step 6:
403 can be fit into 3756 9 times, resulting in a remainder of 129.
Write down 9 as next digit of the result. 
Result so far: 2159.0
Deduct 3627 from 3756 and we're left with 129.
Take the next digit (6) from the dividend and append it to 129, then repeat: 1296 / 403

On to step 7:
403 goes into 1296 3 times with a remainder of 87.
Write down 3 as next digit of the result. 
Result so far: 21593.0
If we subtract 1209 from 1296, we get 87.
Fetch the next digit (6) from the dividend, attach it to 87 and continue: 876 / 403

On to step 8:
If we divide 876 by 403, we get 2 and a remainder of 70.
Write down 2 as next digit of the result. 
Result so far: 215932.0
If we take 806 away from 876, we end up with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Step 9:
700 divided by 403 is 1 with a remainder of 297.
The number 1 becomes the next digit in our result. 
Result so far: 215932.1
Subtract 403 from 700 to get 297.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2970, and continue the process.

Moving on to step 10:
2970 divided by 403 is 7 with a remainder of 149.
The number 7 becomes the next digit in our result. 
Result so far: 215932.17
If we subtract 2821 from 2970, we get 149.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1490, and continue the process.

Let's proceed to step 11:
403 goes into 1490 3 times with a remainder of 281.
Record the quotient 3 as the next digit in the result. 
Result so far: 215932.173
Subtracting 1209 from 1490 leaves us with 281.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2810, and continue the process.

On to step 12:
The number 403 fits into 2810 6 times, leaving a remainder of 392.
Record the quotient 6 as the next digit in the result. 
Result so far: 215932.1736
If we take 2418 away from 2810, we end up with 392.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3920, and continue the process.

On to step 13:
If we divide 3920 by 403, we get 9 and a remainder of 293.
Write down 9 as next digit of the result. 
Result so far: 215932.17369
The remainder is 293 after subtracting 3627 from 3920.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2930, and continue the process.

Step 14:
403 goes into 2930 7 times with a remainder of 109.
The number 7 becomes the next digit in our result. 
Result so far: 215932.173697
The remainder is 109 after subtracting 2821 from 2930.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1090, and continue the process.

Going ahead to step 15:
403 goes into 1090 2 times with a remainder of 284.
Use 2 as the next digit of our solution. 
Result so far: 215932.1736972
The remainder is 284 after subtracting 806 from 1090.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2840, and continue the process.

Let's proceed to step 16:
403 goes into 2840 7 times with a remainder of 19.
Record the quotient 7 as the next digit in the result. 
Result so far: 215932.17369727
If we subtract 2821 from 2840, we get 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

The quotient of the division is 215932.17369727, and the remainder is 1.9e-08.
