We look at the division of 61231126 by 815 
Let's see how many times 815 fits into 61231126.

Step 1:
815 can be fit into 6 0 times, resulting in a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Grab the next digit (1) from the dividend, add it to 6, then carry on: 61 / 815

Step 2:
815 goes into 61 0 times with a remainder of 61.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 61 to get 61.
Take the next digit (2) from the dividend and append it to 61, then repeat: 612 / 815

Moving on to step 3:
If we divide 612 by 815, we get 0 and a remainder of 612.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 612, we get 612.
Grab the next digit (3) from the dividend, add it to 612, then carry on: 6123 / 815

Step 4:
815 can be fit into 6123 7 times, resulting in a remainder of 418.
The next digit of our result is 7. 
Result so far: 7.0
If we subtract 5705 from 6123, we get 418.
Grab the next digit (1) from the dividend, add it to 418, then carry on: 4181 / 815

Let's proceed to step 5:
815 can be fit into 4181 5 times, resulting in a remainder of 106.
Write down 5 as next digit of the result. 
Result so far: 75.0
If we take 4075 away from 4181, we end up with 106.
Grab the next digit (1) from the dividend, add it to 106, then carry on: 1061 / 815

Going ahead to step 6:
815 goes into 1061 1 times with a remainder of 246.
Put 1 as the next digit of the answer. 
Result so far: 751.0
If we take 815 away from 1061, we end up with 246.
Grab the next digit (2) from the dividend, add it to 246, then carry on: 2462 / 815

Moving on to step 7:
The number 815 fits into 2462 3 times, leaving a remainder of 17.
The next digit of our result is 3. 
Result so far: 7513.0
Subtracting 2445 from 2462 leaves us with 17.
Grab the next digit (6) from the dividend, add it to 17, then carry on: 176 / 815

Step 8:
815 goes into 176 0 times with a remainder of 176.
Put 0 as the next digit of the answer. 
Result so far: 75130.0
Subtracting 0 from 176 leaves us with 176.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1760, and continue the process.

On to step 9:
815 goes into 1760 2 times with a remainder of 130.
Use 2 as the next digit of our solution. 
Result so far: 75130.2
If we take 1630 away from 1760, we end up with 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

Step 10:
1300 divided by 815 is 1 with a remainder of 485.
The number 1 becomes the next digit in our result. 
Result so far: 75130.21
Subtract 815 from 1300 to get 485.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4850, and continue the process.

Going ahead to step 11:
The number 815 fits into 4850 5 times, leaving a remainder of 775.
The next digit of our result is 5. 
Result so far: 75130.215
The remainder is 775 after subtracting 4075 from 4850.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7750, and continue the process.

On to step 12:
When dividing 7750 by 815, we get 9 with a remainder of 415.
The number 9 becomes the next digit in our result. 
Result so far: 75130.2159
If we take 7335 away from 7750, we end up with 415.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4150, and continue the process.

Let's proceed to step 13:
4150 divided by 815 is 5 with a remainder of 75.
The number 5 becomes the next digit in our result. 
Result so far: 75130.21595
The remainder is 75 after subtracting 4075 from 4150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Moving on to step 14:
If we divide 750 by 815, we get 0 and a remainder of 750.
Put 0 as the next digit of the answer. 
Result so far: 75130.21595
Deduct 0 from 750 and we're left with 750.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7500, and continue the process.

Going ahead to step 15:
The number 815 fits into 7500 9 times, leaving a remainder of 165.
The next digit of our result is 9. 
Result so far: 75130.2159509
If we subtract 7335 from 7500, we get 165.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1650, and continue the process.

Step 16:
815 can be fit into 1650 2 times, resulting in a remainder of 20.
Use 2 as the next digit of our solution. 
Result so far: 75130.21595092
If we subtract 1630 from 1650, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

The quotient of the division is 75130.21595092, and the remainder is 2e-08.
