Let's divide 31080086 by 286
Our goal is to divide 31080086 by 286.

On to step 1:
3 divided by 286 is 0 with a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Append the next digit (1) from the dividend to 3 and continue with: 31 / 286

Going ahead to step 2:
When dividing 31 by 286, we get 0 with a remainder of 31.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 31 leaves us with 31.
Append the next digit (0) from the dividend to 31 and continue with: 310 / 286

Moving on to step 3:
When dividing 310 by 286, we get 1 with a remainder of 24.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Deduct 286 from 310 and we're left with 24.
Append the next digit (8) from the dividend to 24 and continue with: 248 / 286

On to step 4:
248 divided by 286 is 0 with a remainder of 248.
Use 0 as the next digit of our solution. 
Result so far: 10.0
If we subtract 0 from 248, we get 248.
Bring next digit (0) of the dividend behind the 248 and repeat the process: 2480 / 286

Step 5:
When dividing 2480 by 286, we get 8 with a remainder of 192.
Use 8 as the next digit of our solution. 
Result so far: 108.0
Subtract 2288 from 2480 to get 192.
Take the next digit (0) from the dividend and append it to 192, then repeat: 1920 / 286

Advancing to step 6:
1920 divided by 286 is 6 with a remainder of 204.
The next digit of our result is 6. 
Result so far: 1086.0
If we subtract 1716 from 1920, we get 204.
Fetch the next digit (8) from the dividend, attach it to 204 and continue: 2048 / 286

Step 7:
286 can be fit into 2048 7 times, resulting in a remainder of 46.
Write down 7 as next digit of the result. 
Result so far: 10867.0
The remainder is 46 after subtracting 2002 from 2048.
Fetch the next digit (6) from the dividend, attach it to 46 and continue: 466 / 286

Step 8:
If we divide 466 by 286, we get 1 and a remainder of 180.
Use 1 as the next digit of our solution. 
Result so far: 108671.0
Subtract 286 from 466 to get 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

Advancing to step 9:
If we divide 1800 by 286, we get 6 and a remainder of 84.
Put 6 as the next digit of the answer. 
Result so far: 108671.6
If we take 1716 away from 1800, we end up with 84.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

Let's proceed to step 10:
The number 286 fits into 840 2 times, leaving a remainder of 268.
Record the quotient 2 as the next digit in the result. 
Result so far: 108671.62
The remainder is 268 after subtracting 572 from 840.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2680, and continue the process.

Let's proceed to step 11:
286 goes into 2680 9 times with a remainder of 106.
Record the quotient 9 as the next digit in the result. 
Result so far: 108671.629
If we take 2574 away from 2680, we end up with 106.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1060, and continue the process.

Let's proceed to step 12:
286 can be fit into 1060 3 times, resulting in a remainder of 202.
Write down 3 as next digit of the result. 
Result so far: 108671.6293
Subtract 858 from 1060 to get 202.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2020, and continue the process.

On to step 13:
The number 286 fits into 2020 7 times, leaving a remainder of 18.
The next digit of our result is 7. 
Result so far: 108671.62937
Subtracting 2002 from 2020 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.

On to step 14:
286 can be fit into 180 0 times, resulting in a remainder of 180.
Record the quotient 0 as the next digit in the result. 
Result so far: 108671.62937
Subtract 0 from 180 to get 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

Step 15:
286 can be fit into 1800 6 times, resulting in a remainder of 84.
Write down 6 as next digit of the result. 
Result so far: 108671.6293706
Subtracting 1716 from 1800 leaves us with 84.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

Step 16:
286 goes into 840 2 times with a remainder of 268.
Record the quotient 2 as the next digit in the result. 
Result so far: 108671.62937062
The remainder is 268 after subtracting 572 from 840.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2680, and continue the process.

The quotient of the division is 108671.62937062, and the remainder is 2.68e-07.
