We look at the division of 813891 by 76 
We want to figure out the number of times 813891 can be divided by 76.

On to step 1:
8 divided by 76 is 0 with 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 (1) of the dividend behind the 8 and repeat the process: 81 / 76

Moving on to step 2:
The number 76 fits into 81 1 times, leaving a remainder of 5.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtract 76 from 81 to get 5.
Append the next digit (3) from the dividend to 5 and continue with: 53 / 76

Advancing to step 3:
When dividing 53 by 76, we get 0 with a remainder of 53.
Record the quotient 0 as the next digit in the result. 
Result so far: 10.0
Deduct 0 from 53 and we're left with 53.
Grab the next digit (8) from the dividend, add it to 53, then carry on: 538 / 76

Let's proceed to step 4:
When dividing 538 by 76, we get 7 with a remainder of 6.
Put 7 as the next digit of the answer. 
Result so far: 107.0
Deduct 532 from 538 and we're left with 6.
Include the next digit (9) from the dividend after 6, then repeat: 69 / 76

Moving on to step 5:
69 divided by 76 is 0 with a remainder of 69.
Record the quotient 0 as the next digit in the result. 
Result so far: 1070.0
Deduct 0 from 69 and we're left with 69.
Include the next digit (1) from the dividend after 69, then repeat: 691 / 76

Moving on to step 6:
76 can be fit into 691 9 times, resulting in a remainder of 7.
Write down 9 as next digit of the result. 
Result so far: 10709.0
The remainder is 7 after subtracting 684 from 691.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

On to step 7:
The number 76 fits into 70 0 times, leaving a remainder of 70.
The next digit of our result is 0. 
Result so far: 10709.0
If we take 0 away from 70, 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.

Advancing to step 8:
700 divided by 76 is 9 with a remainder of 16.
The next digit of our result is 9. 
Result so far: 10709.09
If we subtract 684 from 700, we get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Step 9:
If we divide 160 by 76, we get 2 and a remainder of 8.
The next digit of our result is 2. 
Result so far: 10709.092
Subtract 152 from 160 to 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 10:
80 divided by 76 is 1 with a remainder of 4.
Write down 1 as next digit of the result. 
Result so far: 10709.0921
The remainder is 4 after subtracting 76 from 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Let's proceed to step 11:
76 can be fit into 40 0 times, resulting in a remainder of 40.
Write down 0 as next digit of the result. 
Result so far: 10709.0921
Subtract 0 from 40 to get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Going ahead to step 12:
The number 76 fits into 400 5 times, leaving a remainder of 20.
Record the quotient 5 as the next digit in the result. 
Result so far: 10709.092105
Subtracting 380 from 400 leaves us with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

On to step 13:
If we divide 200 by 76, we get 2 and a remainder of 48.
The number 2 becomes the next digit in our result. 
Result so far: 10709.0921052
Subtracting 152 from 200 leaves us with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Advancing to step 14:
If we divide 480 by 76, we get 6 and a remainder of 24.
Use 6 as the next digit of our solution. 
Result so far: 10709.09210526
Subtracting 456 from 480 leaves us with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

The final outcome is 10709.09210526, with a leftover of 2.4e-08.
