We're dividing 13191720 by 801 
We want to divide 13191720 by 801.

Moving on to step 1:
1 divided by 801 is 0 with a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Fetch the next digit (3) from the dividend, attach it to 1 and continue: 13 / 801

On to step 2:
13 divided by 801 is 0 with a remainder of 13.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 13 leaves us with 13.
Include the next digit (1) from the dividend after 13, then repeat: 131 / 801

On to step 3:
If we divide 131 by 801, we get 0 and a remainder of 131.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 131 and we're left with 131.
Grab the next digit (9) from the dividend, add it to 131, then carry on: 1319 / 801

Moving on to step 4:
When dividing 1319 by 801, we get 1 with a remainder of 518.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtract 801 from 1319 to get 518.
Bring next digit (1) of the dividend behind the 518 and repeat the process: 5181 / 801

Moving on to step 5:
801 can be fit into 5181 6 times, resulting in a remainder of 375.
Record the quotient 6 as the next digit in the result. 
Result so far: 16.0
Deduct 4806 from 5181 and we're left with 375.
Take the next digit (7) from the dividend and append it to 375, then repeat: 3757 / 801

Moving on to step 6:
The number 801 fits into 3757 4 times, leaving a remainder of 553.
Record the quotient 4 as the next digit in the result. 
Result so far: 164.0
Subtracting 3204 from 3757 leaves us with 553.
Bring next digit (2) of the dividend behind the 553 and repeat the process: 5532 / 801

Moving on to step 7:
If we divide 5532 by 801, we get 6 and a remainder of 726.
The next digit of our result is 6. 
Result so far: 1646.0
If we take 4806 away from 5532, we end up with 726.
Include the next digit (0) from the dividend after 726, then repeat: 7260 / 801

Step 8:
When dividing 7260 by 801, we get 9 with a remainder of 51.
Use 9 as the next digit of our solution. 
Result so far: 16469.0
Deduct 7209 from 7260 and we're left with 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

Going ahead to step 9:
The number 801 fits into 510 0 times, leaving a remainder of 510.
The number 0 becomes the next digit in our result. 
Result so far: 16469.0
Deduct 0 from 510 and we're left with 510.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5100, and continue the process.

Let's proceed to step 10:
When dividing 5100 by 801, we get 6 with a remainder of 294.
Put 6 as the next digit of the answer. 
Result so far: 16469.06
Subtract 4806 from 5100 to get 294.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2940, and continue the process.

Going ahead to step 11:
801 goes into 2940 3 times with a remainder of 537.
The number 3 becomes the next digit in our result. 
Result so far: 16469.063
If we take 2403 away from 2940, we end up with 537.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5370, and continue the process.

Going ahead to step 12:
If we divide 5370 by 801, we get 6 and a remainder of 564.
Put 6 as the next digit of the answer. 
Result so far: 16469.0636
If we take 4806 away from 5370, we end up with 564.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5640, and continue the process.

Step 13:
5640 divided by 801 is 7 with a remainder of 33.
Use 7 as the next digit of our solution. 
Result so far: 16469.06367
The remainder is 33 after subtracting 5607 from 5640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Going ahead to step 14:
If we divide 330 by 801, we get 0 and a remainder of 330.
Use 0 as the next digit of our solution. 
Result so far: 16469.06367
Subtract 0 from 330 to get 330.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3300, and continue the process.

Moving on to step 15:
3300 divided by 801 is 4 with a remainder of 96.
Write down 4 as next digit of the result. 
Result so far: 16469.0636704
If we subtract 3204 from 3300, we get 96.
Since there are no more digits in the dividend, we add a zero to the remainder making it 960, and continue the process.

Let's proceed to step 16:
When dividing 960 by 801, we get 1 with a remainder of 159.
The next digit of our result is 1. 
Result so far: 16469.06367041
If we take 801 away from 960, we end up with 159.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1590, and continue the process.

The final result is 16469.06367041 with a remainder of 1.59e-07.
