We're dividing 71239181 by 158 
We're looking to find how many times 158 goes into 71239181.

Moving on to step 1:
158 can be fit into 7 0 times, resulting in a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Append the next digit (1) from the dividend to 7 and continue with: 71 / 158

Going ahead to step 2:
The number 158 fits into 71 0 times, leaving a remainder of 71.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 71 to get 71.
Include the next digit (2) from the dividend after 71, then repeat: 712 / 158

Moving on to step 3:
712 divided by 158 is 4 with a remainder of 80.
Put 4 as the next digit of the answer. 
Result so far: 4.0
The remainder is 80 after subtracting 632 from 712.
Bring next digit (3) of the dividend behind the 80 and repeat the process: 803 / 158

On to step 4:
158 goes into 803 5 times with a remainder of 13.
Record the quotient 5 as the next digit in the result. 
Result so far: 45.0
If we take 790 away from 803, we end up with 13.
Take the next digit (9) from the dividend and append it to 13, then repeat: 139 / 158

Step 5:
The number 158 fits into 139 0 times, leaving a remainder of 139.
The number 0 becomes the next digit in our result. 
Result so far: 450.0
Deduct 0 from 139 and we're left with 139.
Append the next digit (1) from the dividend to 139 and continue with: 1391 / 158

Going ahead to step 6:
158 can be fit into 1391 8 times, resulting in a remainder of 127.
Put 8 as the next digit of the answer. 
Result so far: 4508.0
Subtracting 1264 from 1391 leaves us with 127.
Take the next digit (8) from the dividend and append it to 127, then repeat: 1278 / 158

Moving on to step 7:
The number 158 fits into 1278 8 times, leaving a remainder of 14.
Write down 8 as next digit of the result. 
Result so far: 45088.0
If we subtract 1264 from 1278, we get 14.
Take the next digit (1) from the dividend and append it to 14, then repeat: 141 / 158

Step 8:
141 divided by 158 is 0 with a remainder of 141.
The number 0 becomes the next digit in our result. 
Result so far: 450880.0
Subtract 0 from 141 to get 141.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1410, and continue the process.

Going ahead to step 9:
The number 158 fits into 1410 8 times, leaving a remainder of 146.
Put 8 as the next digit of the answer. 
Result so far: 450880.8
If we take 1264 away from 1410, we end up with 146.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1460, and continue the process.

Let's proceed to step 10:
If we divide 1460 by 158, we get 9 and a remainder of 38.
Use 9 as the next digit of our solution. 
Result so far: 450880.89
If we subtract 1422 from 1460, we get 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Let's proceed to step 11:
380 divided by 158 is 2 with a remainder of 64.
The next digit of our result is 2. 
Result so far: 450880.892
If we take 316 away from 380, we end up with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Advancing to step 12:
640 divided by 158 is 4 with a remainder of 8.
Record the quotient 4 as the next digit in the result. 
Result so far: 450880.8924
If we take 632 away from 640, we end up with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Moving on to step 13:
158 goes into 80 0 times with a remainder of 80.
Write down 0 as next digit of the result. 
Result so far: 450880.8924
If we take 0 away from 80, we end up with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Step 14:
The number 158 fits into 800 5 times, leaving a remainder of 10.
The number 5 becomes the next digit in our result. 
Result so far: 450880.892405
Deduct 790 from 800 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 15:
If we divide 100 by 158, we get 0 and a remainder of 100.
Record the quotient 0 as the next digit in the result. 
Result so far: 450880.892405
Subtracting 0 from 100 leaves us with 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Advancing to step 16:
1000 divided by 158 is 6 with a remainder of 52.
Use 6 as the next digit of our solution. 
Result so far: 450880.89240506
If we take 948 away from 1000, we end up with 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 result is 450880.89240506 with a remainder of 5.2e-08.
