We look at the division of 13730121 by 171 
We want to figure out the number of times 13730121 can be divided by 171.

Going ahead to step 1:
1 divided by 171 is 0 with a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Include the next digit (3) from the dividend after 1, then repeat: 13 / 171

Advancing to step 2:
When dividing 13 by 171, we get 0 with a remainder of 13.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 13, we end up with 13.
Append the next digit (7) from the dividend to 13 and continue with: 137 / 171

Moving on to step 3:
137 divided by 171 is 0 with a remainder of 137.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 137 after subtracting 0 from 137.
Bring next digit (3) of the dividend behind the 137 and repeat the process: 1373 / 171

Advancing to step 4:
If we divide 1373 by 171, we get 8 and a remainder of 5.
The next digit of our result is 8. 
Result so far: 8.0
Subtracting 1368 from 1373 leaves us with 5.
Take the next digit (0) from the dividend and append it to 5, then repeat: 50 / 171

Going ahead to step 5:
171 goes into 50 0 times with a remainder of 50.
Put 0 as the next digit of the answer. 
Result so far: 80.0
Subtracting 0 from 50 leaves us with 50.
Fetch the next digit (1) from the dividend, attach it to 50 and continue: 501 / 171

Advancing to step 6:
501 divided by 171 is 2 with a remainder of 159.
The next digit of our result is 2. 
Result so far: 802.0
Subtracting 342 from 501 leaves us with 159.
Include the next digit (2) from the dividend after 159, then repeat: 1592 / 171

Let's proceed to step 7:
171 can be fit into 1592 9 times, resulting in a remainder of 53.
Put 9 as the next digit of the answer. 
Result so far: 8029.0
The remainder is 53 after subtracting 1539 from 1592.
Take the next digit (1) from the dividend and append it to 53, then repeat: 531 / 171

Step 8:
171 can be fit into 531 3 times, resulting in a remainder of 18.
The number 3 becomes the next digit in our result. 
Result so far: 80293.0
The remainder is 18 after subtracting 513 from 531.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Advancing to step 9:
180 divided by 171 is 1 with a remainder of 9.
Record the quotient 1 as the next digit in the result. 
Result so far: 80293.1
If we subtract 171 from 180, we get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Step 10:
171 goes into 90 0 times with a remainder of 90.
The next digit of our result is 0. 
Result so far: 80293.1
Deduct 0 from 90 and we're left with 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

Moving on to step 11:
171 can be fit into 900 5 times, resulting in a remainder of 45.
Use 5 as the next digit of our solution. 
Result so far: 80293.105
If we take 855 away from 900, we end up with 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Step 12:
If we divide 450 by 171, we get 2 and a remainder of 108.
Use 2 as the next digit of our solution. 
Result so far: 80293.1052
If we subtract 342 from 450, we get 108.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1080, and continue the process.

Moving on to step 13:
171 can be fit into 1080 6 times, resulting in a remainder of 54.
The number 6 becomes the next digit in our result. 
Result so far: 80293.10526
Subtracting 1026 from 1080 leaves us with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Step 14:
540 divided by 171 is 3 with a remainder of 27.
Record the quotient 3 as the next digit in the result. 
Result so far: 80293.105263
If we subtract 513 from 540, we get 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Going ahead to step 15:
171 can be fit into 270 1 times, resulting in a remainder of 99.
Write down 1 as next digit of the result. 
Result so far: 80293.1052631
Subtracting 171 from 270 leaves us with 99.
Since there are no more digits in the dividend, we add a zero to the remainder making it 990, and continue the process.

On to step 16:
171 goes into 990 5 times with a remainder of 135.
Write down 5 as next digit of the result. 
Result so far: 80293.10526315
Subtracting 855 from 990 leaves us with 135.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1350, and continue the process.

Our division results in 80293.10526315 with a remaining 1.35e-07.
