72285357 ÷ 171 
Our goal is to divide 72285357 by 171.

Going ahead to step 1:
7 divided by 171 is 0 with a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Bring next digit (2) of the dividend behind the 7 and repeat the process: 72 / 171

Going ahead to step 2:
72 divided by 171 is 0 with a remainder of 72.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 72 leaves us with 72.
Fetch the next digit (2) from the dividend, attach it to 72 and continue: 722 / 171

Advancing to step 3:
When dividing 722 by 171, we get 4 with a remainder of 38.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
Subtract 684 from 722 to get 38.
Include the next digit (8) from the dividend after 38, then repeat: 388 / 171

On to step 4:
The number 171 fits into 388 2 times, leaving a remainder of 46.
The number 2 becomes the next digit in our result. 
Result so far: 42.0
Subtracting 342 from 388 leaves us with 46.
Bring next digit (5) of the dividend behind the 46 and repeat the process: 465 / 171

Going ahead to step 5:
If we divide 465 by 171, we get 2 and a remainder of 123.
The number 2 becomes the next digit in our result. 
Result so far: 422.0
Deduct 342 from 465 and we're left with 123.
Include the next digit (3) from the dividend after 123, then repeat: 1233 / 171

Step 6:
171 goes into 1233 7 times with a remainder of 36.
The next digit of our result is 7. 
Result so far: 4227.0
Deduct 1197 from 1233 and we're left with 36.
Grab the next digit (5) from the dividend, add it to 36, then carry on: 365 / 171

Advancing to step 7:
If we divide 365 by 171, we get 2 and a remainder of 23.
Write down 2 as next digit of the result. 
Result so far: 42272.0
If we subtract 342 from 365, we get 23.
Include the next digit (7) from the dividend after 23, then repeat: 237 / 171

On to step 8:
171 goes into 237 1 times with a remainder of 66.
Record the quotient 1 as the next digit in the result. 
Result so far: 422721.0
The remainder is 66 after subtracting 171 from 237.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

On to step 9:
The number 171 fits into 660 3 times, leaving a remainder of 147.
Write down 3 as next digit of the result. 
Result so far: 422721.3
Subtract 513 from 660 to get 147.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1470, and continue the process.

Going ahead to step 10:
If we divide 1470 by 171, we get 8 and a remainder of 102.
Put 8 as the next digit of the answer. 
Result so far: 422721.38
Subtracting 1368 from 1470 leaves us with 102.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1020, and continue the process.

Let's proceed to step 11:
171 can be fit into 1020 5 times, resulting in a remainder of 165.
The next digit of our result is 5. 
Result so far: 422721.385
The remainder is 165 after subtracting 855 from 1020.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1650, and continue the process.

Moving on to step 12:
1650 divided by 171 is 9 with a remainder of 111.
Record the quotient 9 as the next digit in the result. 
Result so far: 422721.3859
The remainder is 111 after subtracting 1539 from 1650.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1110, and continue the process.

Advancing to step 13:
1110 divided by 171 is 6 with a remainder of 84.
The next digit of our result is 6. 
Result so far: 422721.38596
Subtract 1026 from 1110 to get 84.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

Going ahead to step 14:
171 can be fit into 840 4 times, resulting in a remainder of 156.
The next digit of our result is 4. 
Result so far: 422721.385964
The remainder is 156 after subtracting 684 from 840.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1560, and continue the process.

Step 15:
1560 divided by 171 is 9 with a remainder of 21.
Put 9 as the next digit of the answer. 
Result so far: 422721.3859649
The remainder is 21 after subtracting 1539 from 1560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Step 16:
When dividing 210 by 171, we get 1 with a remainder of 39.
Write down 1 as next digit of the result. 
Result so far: 422721.38596491
If we subtract 171 from 210, we get 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

After the division, we end up with 422721.38596491 and a remainder of 3.9e-08.
