We look at the division of 81799643 by 812 
We want to figure out the number of times 81799643 can be divided by 812.

Going ahead to step 1:
When dividing 8 by 812, we get 0 with a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Grab the next digit (1) from the dividend, add it to 8, then carry on: 81 / 812

On to step 2:
812 can be fit into 81 0 times, resulting in a remainder of 81.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 81, we end up with 81.
Include the next digit (7) from the dividend after 81, then repeat: 817 / 812

Moving on to step 3:
When dividing 817 by 812, we get 1 with a remainder of 5.
The next digit of our result is 1. 
Result so far: 1.0
Deduct 812 from 817 and we're left with 5.
Fetch the next digit (9) from the dividend, attach it to 5 and continue: 59 / 812

Step 4:
If we divide 59 by 812, we get 0 and a remainder of 59.
Record the quotient 0 as the next digit in the result. 
Result so far: 10.0
Deduct 0 from 59 and we're left with 59.
Bring next digit (9) of the dividend behind the 59 and repeat the process: 599 / 812

Let's proceed to step 5:
When dividing 599 by 812, we get 0 with a remainder of 599.
The number 0 becomes the next digit in our result. 
Result so far: 100.0
Subtract 0 from 599 to get 599.
Fetch the next digit (6) from the dividend, attach it to 599 and continue: 5996 / 812

Let's proceed to step 6:
812 goes into 5996 7 times with a remainder of 312.
Put 7 as the next digit of the answer. 
Result so far: 1007.0
Subtract 5684 from 5996 to get 312.
Include the next digit (4) from the dividend after 312, then repeat: 3124 / 812

Let's proceed to step 7:
When dividing 3124 by 812, we get 3 with a remainder of 688.
Write down 3 as next digit of the result. 
Result so far: 10073.0
Deduct 2436 from 3124 and we're left with 688.
Bring next digit (3) of the dividend behind the 688 and repeat the process: 6883 / 812

On to step 8:
If we divide 6883 by 812, we get 8 and a remainder of 387.
The number 8 becomes the next digit in our result. 
Result so far: 100738.0
The remainder is 387 after subtracting 6496 from 6883.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3870, and continue the process.

Let's proceed to step 9:
If we divide 3870 by 812, we get 4 and a remainder of 622.
Record the quotient 4 as the next digit in the result. 
Result so far: 100738.4
Subtract 3248 from 3870 to get 622.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6220, and continue the process.

Let's proceed to step 10:
The number 812 fits into 6220 7 times, leaving a remainder of 536.
The next digit of our result is 7. 
Result so far: 100738.47
Deduct 5684 from 6220 and we're left with 536.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5360, and continue the process.

Advancing to step 11:
If we divide 5360 by 812, we get 6 and a remainder of 488.
Put 6 as the next digit of the answer. 
Result so far: 100738.476
The remainder is 488 after subtracting 4872 from 5360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4880, and continue the process.

Moving on to step 12:
The number 812 fits into 4880 6 times, leaving a remainder of 8.
The next digit of our result is 6. 
Result so far: 100738.4766
If we take 4872 away from 4880, we end up with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

The quotient of the division is 100738.4766, and the remainder is 8e-05.
