Let's divide 181991 by 89
We want to figure out the number of times 181991 can be divided by 89.

Advancing to step 1:
If we divide 1 by 89, we get 0 and a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Bring next digit (8) of the dividend behind the 1 and repeat the process: 18 / 89

On to step 2:
89 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 (1) from the dividend to 18 and continue with: 181 / 89

Moving on to step 3:
The number 89 fits into 181 2 times, leaving a remainder of 3.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
Subtracting 178 from 181 leaves us with 3.
Grab the next digit (9) from the dividend, add it to 3, then carry on: 39 / 89

Going ahead to step 4:
39 divided by 89 is 0 with a remainder of 39.
Write down 0 as next digit of the result. 
Result so far: 20.0
Subtracting 0 from 39 leaves us with 39.
Append the next digit (9) from the dividend to 39 and continue with: 399 / 89

Let's proceed to step 5:
When dividing 399 by 89, we get 4 with a remainder of 43.
Record the quotient 4 as the next digit in the result. 
Result so far: 204.0
Subtracting 356 from 399 leaves us with 43.
Append the next digit (1) from the dividend to 43 and continue with: 431 / 89

Advancing to step 6:
When dividing 431 by 89, we get 4 with a remainder of 75.
Put 4 as the next digit of the answer. 
Result so far: 2044.0
If we take 356 away from 431, we end up 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.

Step 7:
89 can be fit into 750 8 times, resulting in a remainder of 38.
Put 8 as the next digit of the answer. 
Result so far: 2044.8
If we subtract 712 from 750, 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.

Moving on to step 8:
380 divided by 89 is 4 with a remainder of 24.
Use 4 as the next digit of our solution. 
Result so far: 2044.84
The remainder is 24 after subtracting 356 from 380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

On to step 9:
89 can be fit into 240 2 times, resulting in a remainder of 62.
The number 2 becomes the next digit in our result. 
Result so far: 2044.842
The remainder is 62 after subtracting 178 from 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Moving on to step 10:
If we divide 620 by 89, we get 6 and a remainder of 86.
Write down 6 as next digit of the result. 
Result so far: 2044.8426
If we take 534 away from 620, we end up with 86.
Since there are no more digits in the dividend, we add a zero to the remainder making it 860, and continue the process.

Going ahead to step 11:
The number 89 fits into 860 9 times, leaving a remainder of 59.
Put 9 as the next digit of the answer. 
Result so far: 2044.84269
If we subtract 801 from 860, we get 59.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

Going ahead to step 12:
89 can be fit into 590 6 times, resulting in a remainder of 56.
The next digit of our result is 6. 
Result so far: 2044.842696
If we take 534 away from 590, we end up with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

On to step 13:
The number 89 fits into 560 6 times, leaving a remainder of 26.
The next digit of our result is 6. 
Result so far: 2044.8426966
Subtracting 534 from 560 leaves us with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Our division results in 2044.8426966 with a remaining 2.6e-07.
