91890861 ÷ 297 
Our goal is to divide 91890861 by 297.

On to step 1:
297 goes into 9 0 times with a remainder of 9.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 9 and we're left with 9.
Append the next digit (1) from the dividend to 9 and continue with: 91 / 297

Going ahead to step 2:
91 divided by 297 is 0 with a remainder of 91.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 91, we get 91.
Take the next digit (8) from the dividend and append it to 91, then repeat: 918 / 297

Moving on to step 3:
918 divided by 297 is 3 with a remainder of 27.
Write down 3 as next digit of the result. 
Result so far: 3.0
The remainder is 27 after subtracting 891 from 918.
Take the next digit (9) from the dividend and append it to 27, then repeat: 279 / 297

Advancing to step 4:
When dividing 279 by 297, we get 0 with a remainder of 279.
Record the quotient 0 as the next digit in the result. 
Result so far: 30.0
If we subtract 0 from 279, we get 279.
Include the next digit (0) from the dividend after 279, then repeat: 2790 / 297

Moving on to step 5:
297 goes into 2790 9 times with a remainder of 117.
The next digit of our result is 9. 
Result so far: 309.0
Subtracting 2673 from 2790 leaves us with 117.
Include the next digit (8) from the dividend after 117, then repeat: 1178 / 297

Moving on to step 6:
297 can be fit into 1178 3 times, resulting in a remainder of 287.
Write down 3 as next digit of the result. 
Result so far: 3093.0
Subtract 891 from 1178 to get 287.
Grab the next digit (6) from the dividend, add it to 287, then carry on: 2876 / 297

Let's proceed to step 7:
2876 divided by 297 is 9 with a remainder of 203.
Record the quotient 9 as the next digit in the result. 
Result so far: 30939.0
Subtract 2673 from 2876 to get 203.
Fetch the next digit (1) from the dividend, attach it to 203 and continue: 2031 / 297

Advancing to step 8:
When dividing 2031 by 297, we get 6 with a remainder of 249.
The number 6 becomes the next digit in our result. 
Result so far: 309396.0
Subtracting 1782 from 2031 leaves us with 249.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2490, and continue the process.

On to step 9:
When dividing 2490 by 297, we get 8 with a remainder of 114.
The next digit of our result is 8. 
Result so far: 309396.8
Deduct 2376 from 2490 and we're left with 114.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1140, and continue the process.

Advancing to step 10:
The number 297 fits into 1140 3 times, leaving a remainder of 249.
Write down 3 as next digit of the result. 
Result so far: 309396.83
If we take 891 away from 1140, we end up with 249.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2490, and continue the process.

Moving on to step 11:
297 can be fit into 2490 8 times, resulting in a remainder of 114.
Use 8 as the next digit of our solution. 
Result so far: 309396.838
Subtract 2376 from 2490 to get 114.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1140, and continue the process.

Going ahead to step 12:
If we divide 1140 by 297, we get 3 and a remainder of 249.
The number 3 becomes the next digit in our result. 
Result so far: 309396.8383
If we subtract 891 from 1140, we get 249.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2490, and continue the process.

Advancing to step 13:
297 goes into 2490 8 times with a remainder of 114.
Put 8 as the next digit of the answer. 
Result so far: 309396.83838
The remainder is 114 after subtracting 2376 from 2490.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1140, and continue the process.

Moving on to step 14:
1140 divided by 297 is 3 with a remainder of 249.
Write down 3 as next digit of the result. 
Result so far: 309396.838383
If we take 891 away from 1140, we end up with 249.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2490, and continue the process.

On to step 15:
2490 divided by 297 is 8 with a remainder of 114.
Record the quotient 8 as the next digit in the result. 
Result so far: 309396.8383838
The remainder is 114 after subtracting 2376 from 2490.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1140, and continue the process.

On to step 16:
297 can be fit into 1140 3 times, resulting in a remainder of 249.
Use 3 as the next digit of our solution. 
Result so far: 309396.83838383
Deduct 891 from 1140 and we're left with 249.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2490, and continue the process.

The final result is 309396.83838383 with a remainder of 2.49e-07.
