Let's divide 31086819 by 843
We want to figure out the number of times 31086819 can be divided by 843.

Advancing to step 1:
3 divided by 843 is 0 with a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Append the next digit (1) from the dividend to 3 and continue with: 31 / 843

Moving on to step 2:
The number 843 fits into 31 0 times, leaving a remainder of 31.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 31 to get 31.
Grab the next digit (0) from the dividend, add it to 31, then carry on: 310 / 843

On to step 3:
843 can be fit into 310 0 times, resulting in a remainder of 310.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 310 after subtracting 0 from 310.
Fetch the next digit (8) from the dividend, attach it to 310 and continue: 3108 / 843

Moving on to step 4:
843 can be fit into 3108 3 times, resulting in a remainder of 579.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
Subtract 2529 from 3108 to get 579.
Take the next digit (6) from the dividend and append it to 579, then repeat: 5796 / 843

Moving on to step 5:
The number 843 fits into 5796 6 times, leaving a remainder of 738.
Write down 6 as next digit of the result. 
Result so far: 36.0
Subtract 5058 from 5796 to get 738.
Append the next digit (8) from the dividend to 738 and continue with: 7388 / 843

On to step 6:
The number 843 fits into 7388 8 times, leaving a remainder of 644.
The number 8 becomes the next digit in our result. 
Result so far: 368.0
If we take 6744 away from 7388, we end up with 644.
Fetch the next digit (1) from the dividend, attach it to 644 and continue: 6441 / 843

Let's proceed to step 7:
When dividing 6441 by 843, we get 7 with a remainder of 540.
Put 7 as the next digit of the answer. 
Result so far: 3687.0
The remainder is 540 after subtracting 5901 from 6441.
Bring next digit (9) of the dividend behind the 540 and repeat the process: 5409 / 843

On to step 8:
When dividing 5409 by 843, we get 6 with a remainder of 351.
Record the quotient 6 as the next digit in the result. 
Result so far: 36876.0
Subtract 5058 from 5409 to get 351.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3510, and continue the process.

Advancing to step 9:
3510 divided by 843 is 4 with a remainder of 138.
The number 4 becomes the next digit in our result. 
Result so far: 36876.4
Deduct 3372 from 3510 and we're left with 138.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1380, and continue the process.

Let's proceed to step 10:
If we divide 1380 by 843, we get 1 and a remainder of 537.
Record the quotient 1 as the next digit in the result. 
Result so far: 36876.41
The remainder is 537 after subtracting 843 from 1380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5370, and continue the process.

Going ahead to step 11:
If we divide 5370 by 843, we get 6 and a remainder of 312.
The next digit of our result is 6. 
Result so far: 36876.416
Subtract 5058 from 5370 to get 312.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3120, and continue the process.

Step 12:
If we divide 3120 by 843, we get 3 and a remainder of 591.
Record the quotient 3 as the next digit in the result. 
Result so far: 36876.4163
Subtract 2529 from 3120 to get 591.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5910, and continue the process.

Step 13:
843 can be fit into 5910 7 times, resulting in a remainder of 9.
Write down 7 as next digit of the result. 
Result so far: 36876.41637
Subtract 5901 from 5910 to get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

On to step 14:
843 goes into 90 0 times with a remainder of 90.
Use 0 as the next digit of our solution. 
Result so far: 36876.41637
Subtracting 0 from 90 leaves us with 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

Step 15:
900 divided by 843 is 1 with a remainder of 57.
The number 1 becomes the next digit in our result. 
Result so far: 36876.4163701
Deduct 843 from 900 and we're left with 57.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

On to step 16:
570 divided by 843 is 0 with a remainder of 570.
The number 0 becomes the next digit in our result. 
Result so far: 36876.4163701
Deduct 0 from 570 and we're left with 570.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5700, and continue the process.

After the division, we end up with 36876.4163701 and a remainder of 5.7e-07.
