We divide 1720177 by 815
We want to divide 1720177 by 815.

Advancing to step 1:
1 divided by 815 is 0 with a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Bring next digit (7) of the dividend behind the 1 and repeat the process: 17 / 815

Moving on to step 2:
17 divided by 815 is 0 with a remainder of 17.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 17, we end up with 17.
Grab the next digit (2) from the dividend, add it to 17, then carry on: 172 / 815

Let's proceed to step 3:
If we divide 172 by 815, we get 0 and a remainder of 172.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 172 to get 172.
Take the next digit (0) from the dividend and append it to 172, then repeat: 1720 / 815

On to step 4:
When dividing 1720 by 815, we get 2 with a remainder of 90.
Write down 2 as next digit of the result. 
Result so far: 2.0
Deduct 1630 from 1720 and we're left with 90.
Grab the next digit (1) from the dividend, add it to 90, then carry on: 901 / 815

Advancing to step 5:
815 goes into 901 1 times with a remainder of 86.
Put 1 as the next digit of the answer. 
Result so far: 21.0
Deduct 815 from 901 and we're left with 86.
Grab the next digit (7) from the dividend, add it to 86, then carry on: 867 / 815

Let's proceed to step 6:
815 goes into 867 1 times with a remainder of 52.
The next digit of our result is 1. 
Result so far: 211.0
The remainder is 52 after subtracting 815 from 867.
Append the next digit (7) from the dividend to 52 and continue with: 527 / 815

Step 7:
815 can be fit into 527 0 times, resulting in a remainder of 527.
Record the quotient 0 as the next digit in the result. 
Result so far: 2110.0
Deduct 0 from 527 and we're left with 527.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5270, and continue the process.

Let's proceed to step 8:
815 goes into 5270 6 times with a remainder of 380.
Record the quotient 6 as the next digit in the result. 
Result so far: 2110.6
If we subtract 4890 from 5270, we get 380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3800, and continue the process.

On to step 9:
The number 815 fits into 3800 4 times, leaving a remainder of 540.
Write down 4 as next digit of the result. 
Result so far: 2110.64
Subtracting 3260 from 3800 leaves us with 540.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5400, and continue the process.

Moving on to step 10:
815 goes into 5400 6 times with a remainder of 510.
The number 6 becomes the next digit in our result. 
Result so far: 2110.646
The remainder is 510 after subtracting 4890 from 5400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5100, and continue the process.

Step 11:
5100 divided by 815 is 6 with a remainder of 210.
The next digit of our result is 6. 
Result so far: 2110.6466
If we subtract 4890 from 5100, we get 210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2100, and continue the process.

The quotient of the division is 2110.6466, and the remainder is 0.0021.
