We're dividing 198643 by 91 
Our goal is to divide 198643 by 91.

Advancing to step 1:
The number 91 fits into 1 0 times, leaving a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Grab the next digit (9) from the dividend, add it to 1, then carry on: 19 / 91

Step 2:
91 can be fit into 19 0 times, resulting in a remainder of 19.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 19 leaves us with 19.
Include the next digit (8) from the dividend after 19, then repeat: 198 / 91

On to step 3:
If we divide 198 by 91, we get 2 and a remainder of 16.
Use 2 as the next digit of our solution. 
Result so far: 2.0
Deduct 182 from 198 and we're left with 16.
Take the next digit (6) from the dividend and append it to 16, then repeat: 166 / 91

Advancing to step 4:
166 divided by 91 is 1 with a remainder of 75.
The number 1 becomes the next digit in our result. 
Result so far: 21.0
Deduct 91 from 166 and we're left with 75.
Append the next digit (4) from the dividend to 75 and continue with: 754 / 91

Advancing to step 5:
91 can be fit into 754 8 times, resulting in a remainder of 26.
The number 8 becomes the next digit in our result. 
Result so far: 218.0
The remainder is 26 after subtracting 728 from 754.
Fetch the next digit (3) from the dividend, attach it to 26 and continue: 263 / 91

Moving on to step 6:
If we divide 263 by 91, we get 2 and a remainder of 81.
Write down 2 as next digit of the result. 
Result so far: 2182.0
If we subtract 182 from 263, we get 81.
Since there are no more digits in the dividend, we add a zero to the remainder making it 810, and continue the process.

Let's proceed to step 7:
When dividing 810 by 91, we get 8 with a remainder of 82.
The next digit of our result is 8. 
Result so far: 2182.8
The remainder is 82 after subtracting 728 from 810.
Since there are no more digits in the dividend, we add a zero to the remainder making it 820, and continue the process.

Advancing to step 8:
When dividing 820 by 91, we get 9 with a remainder of 1.
The next digit of our result is 9. 
Result so far: 2182.89
If we subtract 819 from 820, we get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Going ahead to step 9:
10 divided by 91 is 0 with a remainder of 10.
Record the quotient 0 as the next digit in the result. 
Result so far: 2182.89
Subtracting 0 from 10 leaves us 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.

Moving on to step 10:
If we divide 100 by 91, we get 1 and a remainder of 9.
Use 1 as the next digit of our solution. 
Result so far: 2182.8901
Subtract 91 from 100 to get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Let's proceed to step 11:
91 can be fit into 90 0 times, resulting in a remainder of 90.
Write down 0 as next digit of the result. 
Result so far: 2182.8901
If we take 0 away from 90, we end up with 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

Going ahead to step 12:
91 goes into 900 9 times with a remainder of 81.
Record the quotient 9 as the next digit in the result. 
Result so far: 2182.890109
If we take 819 away from 900, we end up with 81.
Since there are no more digits in the dividend, we add a zero to the remainder making it 810, and continue the process.

Advancing to step 13:
91 can be fit into 810 8 times, resulting in a remainder of 82.
The next digit of our result is 8. 
Result so far: 2182.8901098
Subtracting 728 from 810 leaves us with 82.
Since there are no more digits in the dividend, we add a zero to the remainder making it 820, and continue the process.

Step 14:
91 goes into 820 9 times with a remainder of 1.
Write down 9 as next digit of the result. 
Result so far: 2182.89010989
Subtract 819 from 820 to get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

The quotient of the division is 2182.89010989, and the remainder is 1e-09.
