Let's divide 87453623 by 31
We want to divide 87453623 by 31.

Step 1:
8 divided by 31 is 0 with a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Fetch the next digit (7) from the dividend, attach it to 8 and continue: 87 / 31

Moving on to step 2:
31 can be fit into 87 2 times, resulting in a remainder of 25.
Put 2 as the next digit of the answer. 
Result so far: 2.0
If we take 62 away from 87, we end up with 25.
Fetch the next digit (4) from the dividend, attach it to 25 and continue: 254 / 31

Advancing to step 3:
The number 31 fits into 254 8 times, leaving a remainder of 6.
Put 8 as the next digit of the answer. 
Result so far: 28.0
If we subtract 248 from 254, we get 6.
Take the next digit (5) from the dividend and append it to 6, then repeat: 65 / 31

Going ahead to step 4:
31 goes into 65 2 times with a remainder of 3.
Use 2 as the next digit of our solution. 
Result so far: 282.0
Subtracting 62 from 65 leaves us with 3.
Grab the next digit (3) from the dividend, add it to 3, then carry on: 33 / 31

Advancing to step 5:
When dividing 33 by 31, we get 1 with a remainder of 2.
Write down 1 as next digit of the result. 
Result so far: 2821.0
If we take 31 away from 33, we end up with 2.
Grab the next digit (6) from the dividend, add it to 2, then carry on: 26 / 31

Step 6:
31 goes into 26 0 times with a remainder of 26.
Use 0 as the next digit of our solution. 
Result so far: 28210.0
The remainder is 26 after subtracting 0 from 26.
Append the next digit (2) from the dividend to 26 and continue with: 262 / 31

Going ahead to step 7:
If we divide 262 by 31, we get 8 and a remainder of 14.
Use 8 as the next digit of our solution. 
Result so far: 282108.0
If we take 248 away from 262, we end up with 14.
Bring next digit (3) of the dividend behind the 14 and repeat the process: 143 / 31

Step 8:
When dividing 143 by 31, we get 4 with a remainder of 19.
The next digit of our result is 4. 
Result so far: 2821084.0
Subtract 124 from 143 to 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.

Going ahead to step 9:
190 divided by 31 is 6 with a remainder of 4.
Write down 6 as next digit of the result. 
Result so far: 2821084.6
Subtract 186 from 190 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Step 10:
40 divided by 31 is 1 with a remainder of 9.
The next digit of our result is 1. 
Result so far: 2821084.61
Subtracting 31 from 40 leaves us with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Advancing to step 11:
90 divided by 31 is 2 with a remainder of 28.
The next digit of our result is 2. 
Result so far: 2821084.612
If we subtract 62 from 90, we get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

On to step 12:
31 goes into 280 9 times with a remainder of 1.
Use 9 as the next digit of our solution. 
Result so far: 2821084.6129
Subtracting 279 from 280 leaves us with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Advancing to step 13:
When dividing 10 by 31, we get 0 with a remainder of 10.
The next digit of our result is 0. 
Result so far: 2821084.6129
The remainder is 10 after subtracting 0 from 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 14:
31 can be fit into 100 3 times, resulting in a remainder of 7.
Put 3 as the next digit of the answer. 
Result so far: 2821084.612903
Subtract 93 from 100 to get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Going ahead to step 15:
When dividing 70 by 31, we get 2 with a remainder of 8.
The number 2 becomes the next digit in our result. 
Result so far: 2821084.6129032
If we subtract 62 from 70, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

On to step 16:
31 goes into 80 2 times with a remainder of 18.
Write down 2 as next digit of the result. 
Result so far: 2821084.61290322
The remainder is 18 after subtracting 62 from 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

The final outcome is 2821084.61290322, with a leftover of 1.8e-08.
