68901631 ÷ 171 
We're looking to find how many times 171 goes into 68901631.

Let's proceed to step 1:
When dividing 6 by 171, we get 0 with a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Bring next digit (8) of the dividend behind the 6 and repeat the process: 68 / 171

On to step 2:
When dividing 68 by 171, we get 0 with a remainder of 68.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 68 and we're left with 68.
Append the next digit (9) from the dividend to 68 and continue with: 689 / 171

On to step 3:
The number 171 fits into 689 4 times, leaving a remainder of 5.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
Subtracting 684 from 689 leaves us with 5.
Append the next digit (0) from the dividend to 5 and continue with: 50 / 171

Advancing to step 4:
171 goes into 50 0 times with a remainder of 50.
The number 0 becomes the next digit in our result. 
Result so far: 40.0
If we take 0 away from 50, we end up with 50.
Include the next digit (1) from the dividend after 50, then repeat: 501 / 171

Let's proceed to step 5:
When dividing 501 by 171, we get 2 with a remainder of 159.
Record the quotient 2 as the next digit in the result. 
Result so far: 402.0
If we subtract 342 from 501, we get 159.
Grab the next digit (6) from the dividend, add it to 159, then carry on: 1596 / 171

Let's proceed to step 6:
If we divide 1596 by 171, we get 9 and a remainder of 57.
Record the quotient 9 as the next digit in the result. 
Result so far: 4029.0
Subtracting 1539 from 1596 leaves us with 57.
Append the next digit (3) from the dividend to 57 and continue with: 573 / 171

Moving on to step 7:
171 can be fit into 573 3 times, resulting in a remainder of 60.
Put 3 as the next digit of the answer. 
Result so far: 40293.0
Subtract 513 from 573 to get 60.
Include the next digit (1) from the dividend after 60, then repeat: 601 / 171

Going ahead to step 8:
171 can be fit into 601 3 times, resulting in a remainder of 88.
The next digit of our result is 3. 
Result so far: 402933.0
Deduct 513 from 601 and we're left with 88.
Since there are no more digits in the dividend, we add a zero to the remainder making it 880, and continue the process.

On to step 9:
The number 171 fits into 880 5 times, leaving a remainder of 25.
Use 5 as the next digit of our solution. 
Result so far: 402933.5
If we subtract 855 from 880, we get 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Moving on to step 10:
171 goes into 250 1 times with a remainder of 79.
The next digit of our result is 1. 
Result so far: 402933.51
If we take 171 away from 250, we end up with 79.
Since there are no more digits in the dividend, we add a zero to the remainder making it 790, and continue the process.

Step 11:
171 can be fit into 790 4 times, resulting in a remainder of 106.
Record the quotient 4 as the next digit in the result. 
Result so far: 402933.514
Subtract 684 from 790 to get 106.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1060, and continue the process.

Step 12:
171 can be fit into 1060 6 times, resulting in a remainder of 34.
Write down 6 as next digit of the result. 
Result so far: 402933.5146
If we take 1026 away from 1060, we end up with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Moving on to step 13:
When dividing 340 by 171, we get 1 with a remainder of 169.
Write down 1 as next digit of the result. 
Result so far: 402933.51461
Subtracting 171 from 340 leaves us with 169.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1690, and continue the process.

Advancing to step 14:
If we divide 1690 by 171, we get 9 and a remainder of 151.
Use 9 as the next digit of our solution. 
Result so far: 402933.514619
The remainder is 151 after subtracting 1539 from 1690.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1510, and continue the process.

Going ahead to step 15:
When dividing 1510 by 171, we get 8 with a remainder of 142.
Use 8 as the next digit of our solution. 
Result so far: 402933.5146198
The remainder is 142 after subtracting 1368 from 1510.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1420, and continue the process.

Let's proceed to step 16:
When dividing 1420 by 171, we get 8 with a remainder of 52.
The next digit of our result is 8. 
Result so far: 402933.51461988
If we subtract 1368 from 1420, we get 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

The final outcome is 402933.51461988, with a leftover of 5.2e-08.
