We look at the division of 71458366 by 171 
Let's see how many times 171 fits into 71458366.

Going ahead to step 1:
If we divide 7 by 171, we get 0 and a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Grab the next digit (1) from the dividend, add it to 7, then carry on: 71 / 171

Moving on to step 2:
71 divided by 171 is 0 with a remainder of 71.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 71 after subtracting 0 from 71.
Append the next digit (4) from the dividend to 71 and continue with: 714 / 171

Moving on to step 3:
The number 171 fits into 714 4 times, leaving a remainder of 30.
The next digit of our result is 4. 
Result so far: 4.0
Subtract 684 from 714 to get 30.
Fetch the next digit (5) from the dividend, attach it to 30 and continue: 305 / 171

Advancing to step 4:
171 can be fit into 305 1 times, resulting in a remainder of 134.
The next digit of our result is 1. 
Result so far: 41.0
If we subtract 171 from 305, we get 134.
Grab the next digit (8) from the dividend, add it to 134, then carry on: 1348 / 171

Going ahead to step 5:
171 goes into 1348 7 times with a remainder of 151.
Record the quotient 7 as the next digit in the result. 
Result so far: 417.0
The remainder is 151 after subtracting 1197 from 1348.
Include the next digit (3) from the dividend after 151, then repeat: 1513 / 171

On to step 6:
1513 divided by 171 is 8 with a remainder of 145.
Record the quotient 8 as the next digit in the result. 
Result so far: 4178.0
Subtract 1368 from 1513 to get 145.
Grab the next digit (6) from the dividend, add it to 145, then carry on: 1456 / 171

On to step 7:
171 can be fit into 1456 8 times, resulting in a remainder of 88.
Use 8 as the next digit of our solution. 
Result so far: 41788.0
If we subtract 1368 from 1456, we get 88.
Bring next digit (6) of the dividend behind the 88 and repeat the process: 886 / 171

On to step 8:
The number 171 fits into 886 5 times, leaving a remainder of 31.
Put 5 as the next digit of the answer. 
Result so far: 417885.0
If we take 855 away from 886, we end up with 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

On to step 9:
171 goes into 310 1 times with a remainder of 139.
Use 1 as the next digit of our solution. 
Result so far: 417885.1
If we subtract 171 from 310, we get 139.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1390, and continue the process.

Advancing to step 10:
The number 171 fits into 1390 8 times, leaving a remainder of 22.
Put 8 as the next digit of the answer. 
Result so far: 417885.18
Subtract 1368 from 1390 to get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Advancing to step 11:
171 can be fit into 220 1 times, resulting in a remainder of 49.
Use 1 as the next digit of our solution. 
Result so far: 417885.181
Subtract 171 from 220 to get 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

On to step 12:
When dividing 490 by 171, we get 2 with a remainder of 148.
Use 2 as the next digit of our solution. 
Result so far: 417885.1812
If we take 342 away from 490, we end up with 148.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1480, and continue the process.

Going ahead to step 13:
When dividing 1480 by 171, we get 8 with a remainder of 112.
Use 8 as the next digit of our solution. 
Result so far: 417885.18128
If we subtract 1368 from 1480, we get 112.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1120, and continue the process.

Let's proceed to step 14:
The number 171 fits into 1120 6 times, leaving a remainder of 94.
Use 6 as the next digit of our solution. 
Result so far: 417885.181286
If we take 1026 away from 1120, we end up with 94.
Since there are no more digits in the dividend, we add a zero to the remainder making it 940, and continue the process.

Let's proceed to step 15:
171 can be fit into 940 5 times, resulting in a remainder of 85.
Put 5 as the next digit of the answer. 
Result so far: 417885.1812865
If we subtract 855 from 940, we get 85.
Since there are no more digits in the dividend, we add a zero to the remainder making it 850, and continue the process.

Let's proceed to step 16:
When dividing 850 by 171, we get 4 with a remainder of 166.
Use 4 as the next digit of our solution. 
Result so far: 417885.18128654
Subtract 684 from 850 to get 166.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1660, and continue the process.

The final outcome is 417885.18128654, with a leftover of 1.66e-07.
