We're dividing 12155106 by 812 
Let's see how many times 812 fits into 12155106.

Let's proceed to step 1:
812 can be fit into 1 0 times, resulting in a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Fetch the next digit (2) from the dividend, attach it to 1 and continue: 12 / 812

Going ahead to step 2:
12 divided by 812 is 0 with a remainder of 12.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 12 and we're left with 12.
Fetch the next digit (1) from the dividend, attach it to 12 and continue: 121 / 812

Going ahead to step 3:
The number 812 fits into 121 0 times, leaving a remainder of 121.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 121 leaves us with 121.
Grab the next digit (5) from the dividend, add it to 121, then carry on: 1215 / 812

On to step 4:
If we divide 1215 by 812, we get 1 and a remainder of 403.
The next digit of our result is 1. 
Result so far: 1.0
Subtracting 812 from 1215 leaves us with 403.
Include the next digit (5) from the dividend after 403, then repeat: 4035 / 812

Step 5:
4035 divided by 812 is 4 with a remainder of 787.
The number 4 becomes the next digit in our result. 
Result so far: 14.0
Subtract 3248 from 4035 to get 787.
Bring next digit (1) of the dividend behind the 787 and repeat the process: 7871 / 812

Step 6:
812 goes into 7871 9 times with a remainder of 563.
Use 9 as the next digit of our solution. 
Result so far: 149.0
The remainder is 563 after subtracting 7308 from 7871.
Append the next digit (0) from the dividend to 563 and continue with: 5630 / 812

Moving on to step 7:
When dividing 5630 by 812, we get 6 with a remainder of 758.
The number 6 becomes the next digit in our result. 
Result so far: 1496.0
The remainder is 758 after subtracting 4872 from 5630.
Bring next digit (6) of the dividend behind the 758 and repeat the process: 7586 / 812

Advancing to step 8:
When dividing 7586 by 812, we get 9 with a remainder of 278.
Put 9 as the next digit of the answer. 
Result so far: 14969.0
Subtract 7308 from 7586 to get 278.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2780, and continue the process.

Step 9:
812 goes into 2780 3 times with a remainder of 344.
Write down 3 as next digit of the result. 
Result so far: 14969.3
Subtract 2436 from 2780 to get 344.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3440, and continue the process.

Going ahead to step 10:
812 goes into 3440 4 times with a remainder of 192.
Use 4 as the next digit of our solution. 
Result so far: 14969.34
If we subtract 3248 from 3440, we get 192.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1920, and continue the process.

Moving on to step 11:
812 goes into 1920 2 times with a remainder of 296.
Put 2 as the next digit of the answer. 
Result so far: 14969.342
Subtract 1624 from 1920 to get 296.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2960, and continue the process.

On to step 12:
812 goes into 2960 3 times with a remainder of 524.
The next digit of our result is 3. 
Result so far: 14969.3423
If we subtract 2436 from 2960, we get 524.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5240, and continue the process.

Advancing to step 13:
812 goes into 5240 6 times with a remainder of 368.
Write down 6 as next digit of the result. 
Result so far: 14969.34236
If we subtract 4872 from 5240, we get 368.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3680, and continue the process.

Let's proceed to step 14:
The number 812 fits into 3680 4 times, leaving a remainder of 432.
Write down 4 as next digit of the result. 
Result so far: 14969.342364
Deduct 3248 from 3680 and we're left with 432.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4320, and continue the process.

Going ahead to step 15:
812 can be fit into 4320 5 times, resulting in a remainder of 260.
Use 5 as the next digit of our solution. 
Result so far: 14969.3423645
Subtract 4060 from 4320 to get 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2600, and continue the process.

On to step 16:
2600 divided by 812 is 3 with a remainder of 164.
The next digit of our result is 3. 
Result so far: 14969.34236453
Deduct 2436 from 2600 and we're left with 164.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1640, and continue the process.

The quotient of the division is 14969.34236453, and the remainder is 1.64e-07.
