20677900 ÷ 91 
We want to divide 20677900 by 91.

Going ahead to step 1:
When dividing 2 by 91, we get 0 with a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Include the next digit (0) from the dividend after 2, then repeat: 20 / 91

Moving on to step 2:
20 divided by 91 is 0 with a remainder of 20.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 20 leaves us with 20.
Take the next digit (6) from the dividend and append it to 20, then repeat: 206 / 91

Let's proceed to step 3:
91 goes into 206 2 times with a remainder of 24.
Write down 2 as next digit of the result. 
Result so far: 2.0
Deduct 182 from 206 and we're left with 24.
Bring next digit (7) of the dividend behind the 24 and repeat the process: 247 / 91

Step 4:
If we divide 247 by 91, we get 2 and a remainder of 65.
The next digit of our result is 2. 
Result so far: 22.0
Deduct 182 from 247 and we're left with 65.
Append the next digit (7) from the dividend to 65 and continue with: 657 / 91

On to step 5:
If we divide 657 by 91, we get 7 and a remainder of 20.
Use 7 as the next digit of our solution. 
Result so far: 227.0
Subtract 637 from 657 to get 20.
Include the next digit (9) from the dividend after 20, then repeat: 209 / 91

On to step 6:
91 can be fit into 209 2 times, resulting in a remainder of 27.
Write down 2 as next digit of the result. 
Result so far: 2272.0
If we take 182 away from 209, we end up with 27.
Grab the next digit (0) from the dividend, add it to 27, then carry on: 270 / 91

Moving on to step 7:
91 goes into 270 2 times with a remainder of 88.
The next digit of our result is 2. 
Result so far: 22722.0
If we subtract 182 from 270, we get 88.
Take the next digit (0) from the dividend and append it to 88, then repeat: 880 / 91

On to step 8:
When dividing 880 by 91, we get 9 with a remainder of 61.
Put 9 as the next digit of the answer. 
Result so far: 227229.0
If we subtract 819 from 880, we get 61.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

Moving on to step 9:
91 goes into 610 6 times with a remainder of 64.
Record the quotient 6 as the next digit in the result. 
Result so far: 227229.6
Deduct 546 from 610 and we're left 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.

Let's proceed to step 10:
The number 91 fits into 640 7 times, leaving a remainder of 3.
Record the quotient 7 as the next digit in the result. 
Result so far: 227229.67
If we take 637 away from 640, we end up with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Step 11:
If we divide 30 by 91, we get 0 and a remainder of 30.
Write down 0 as next digit of the result. 
Result so far: 227229.67
The remainder is 30 after subtracting 0 from 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Moving on to step 12:
If we divide 300 by 91, we get 3 and a remainder of 27.
The number 3 becomes the next digit in our result. 
Result so far: 227229.6703
Deduct 273 from 300 and we're left with 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

On to step 13:
270 divided by 91 is 2 with a remainder of 88.
Use 2 as the next digit of our solution. 
Result so far: 227229.67032
If we take 182 away from 270, we end up with 88.
Since there are no more digits in the dividend, we add a zero to the remainder making it 880, and continue the process.

Step 14:
When dividing 880 by 91, we get 9 with a remainder of 61.
The number 9 becomes the next digit in our result. 
Result so far: 227229.670329
The remainder is 61 after subtracting 819 from 880.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

On to step 15:
610 divided by 91 is 6 with a remainder of 64.
Write down 6 as next digit of the result. 
Result so far: 227229.6703296
If we subtract 546 from 610, we get 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Going ahead to step 16:
640 divided by 91 is 7 with a remainder of 3.
Put 7 as the next digit of the answer. 
Result so far: 227229.67032967
Subtracting 637 from 640 leaves us with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

The final result is 227229.67032967 with a remainder of 3e-09.
