We divide 180142 by 91
We're looking to find how many times 91 goes into 180142.

Moving on to step 1:
91 can be fit into 1 0 times, resulting in a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Fetch the next digit (8) from the dividend, attach it to 1 and continue: 18 / 91

Advancing to step 2:
91 can be fit into 18 0 times, resulting in a remainder of 18.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 18, we get 18.
Append the next digit (0) from the dividend to 18 and continue with: 180 / 91

Advancing to step 3:
91 goes into 180 1 times with a remainder of 89.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we take 91 away from 180, we end up with 89.
Include the next digit (1) from the dividend after 89, then repeat: 891 / 91

Moving on to step 4:
If we divide 891 by 91, we get 9 and a remainder of 72.
The number 9 becomes the next digit in our result. 
Result so far: 19.0
The remainder is 72 after subtracting 819 from 891.
Take the next digit (4) from the dividend and append it to 72, then repeat: 724 / 91

Moving on to step 5:
When dividing 724 by 91, we get 7 with a remainder of 87.
Write down 7 as next digit of the result. 
Result so far: 197.0
If we subtract 637 from 724, we get 87.
Append the next digit (2) from the dividend to 87 and continue with: 872 / 91

Step 6:
91 goes into 872 9 times with a remainder of 53.
Put 9 as the next digit of the answer. 
Result so far: 1979.0
Subtract 819 from 872 to get 53.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

Going ahead to step 7:
The number 91 fits into 530 5 times, leaving a remainder of 75.
Use 5 as the next digit of our solution. 
Result so far: 1979.5
If we subtract 455 from 530, we get 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Advancing to step 8:
The number 91 fits into 750 8 times, leaving a remainder of 22.
Record the quotient 8 as the next digit in the result. 
Result so far: 1979.58
Subtract 728 from 750 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.

Moving on to step 9:
If we divide 220 by 91, we get 2 and a remainder of 38.
Write down 2 as next digit of the result. 
Result so far: 1979.582
Deduct 182 from 220 and we're left with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Going ahead to step 10:
380 divided by 91 is 4 with a remainder of 16.
Use 4 as the next digit of our solution. 
Result so far: 1979.5824
Subtracting 364 from 380 leaves us with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Moving on to step 11:
91 goes into 160 1 times with a remainder of 69.
Use 1 as the next digit of our solution. 
Result so far: 1979.58241
If we take 91 away from 160, we end up with 69.
Since there are no more digits in the dividend, we add a zero to the remainder making it 690, and continue the process.

Moving on to step 12:
The number 91 fits into 690 7 times, leaving a remainder of 53.
Put 7 as the next digit of the answer. 
Result so far: 1979.582417
The remainder is 53 after subtracting 637 from 690.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

Advancing to step 13:
91 goes into 530 5 times with a remainder of 75.
Use 5 as the next digit of our solution. 
Result so far: 1979.5824175
Subtracting 455 from 530 leaves us with 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Moving on to step 14:
91 goes into 750 8 times with a remainder of 22.
Put 8 as the next digit of the answer. 
Result so far: 1979.58241758
If we subtract 728 from 750, we 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.

The final result is 1979.58241758 with a remainder of 2.2e-08.
