20878717 ÷ 91 
Our goal is to divide 20878717 by 91.

Step 1:
91 goes into 2 0 times with a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Bring next digit (0) of the dividend behind the 2 and repeat the process: 20 / 91

Moving on to step 2:
If we divide 20 by 91, we get 0 and a remainder of 20.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 20 after subtracting 0 from 20.
Grab the next digit (8) from the dividend, add it to 20, then carry on: 208 / 91

Moving on to step 3:
When dividing 208 by 91, we get 2 with a remainder of 26.
The next digit of our result is 2. 
Result so far: 2.0
Subtract 182 from 208 to get 26.
Fetch the next digit (7) from the dividend, attach it to 26 and continue: 267 / 91

Let's proceed to step 4:
When dividing 267 by 91, we get 2 with a remainder of 85.
Use 2 as the next digit of our solution. 
Result so far: 22.0
Subtracting 182 from 267 leaves us with 85.
Bring next digit (8) of the dividend behind the 85 and repeat the process: 858 / 91

Going ahead to step 5:
The number 91 fits into 858 9 times, leaving a remainder of 39.
Put 9 as the next digit of the answer. 
Result so far: 229.0
Deduct 819 from 858 and we're left with 39.
Take the next digit (7) from the dividend and append it to 39, then repeat: 397 / 91

Going ahead to step 6:
91 can be fit into 397 4 times, resulting in a remainder of 33.
Record the quotient 4 as the next digit in the result. 
Result so far: 2294.0
The remainder is 33 after subtracting 364 from 397.
Bring next digit (1) of the dividend behind the 33 and repeat the process: 331 / 91

Moving on to step 7:
331 divided by 91 is 3 with a remainder of 58.
The number 3 becomes the next digit in our result. 
Result so far: 22943.0
Subtract 273 from 331 to get 58.
Fetch the next digit (7) from the dividend, attach it to 58 and continue: 587 / 91

Let's proceed to step 8:
When dividing 587 by 91, we get 6 with a remainder of 41.
Put 6 as the next digit of the answer. 
Result so far: 229436.0
If we subtract 546 from 587, we get 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Let's proceed to step 9:
91 can be fit into 410 4 times, resulting in a remainder of 46.
Record the quotient 4 as the next digit in the result. 
Result so far: 229436.4
Subtract 364 from 410 to get 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

On to step 10:
The number 91 fits into 460 5 times, leaving a remainder of 5.
Use 5 as the next digit of our solution. 
Result so far: 229436.45
Subtract 455 from 460 to get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Moving on to step 11:
When dividing 50 by 91, we get 0 with a remainder of 50.
Write down 0 as next digit of the result. 
Result so far: 229436.45
Subtracting 0 from 50 leaves us with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

On to step 12:
91 can be fit into 500 5 times, resulting in a remainder of 45.
The next digit of our result is 5. 
Result so far: 229436.4505
Subtracting 455 from 500 leaves us with 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Going ahead to step 13:
91 can be fit into 450 4 times, resulting in a remainder of 86.
Record the quotient 4 as the next digit in the result. 
Result so far: 229436.45054
If we subtract 364 from 450, we get 86.
Since there are no more digits in the dividend, we add a zero to the remainder making it 860, and continue the process.

Advancing to step 14:
91 can be fit into 860 9 times, resulting in a remainder of 41.
The number 9 becomes the next digit in our result. 
Result so far: 229436.450549
If we subtract 819 from 860, we get 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Going ahead to step 15:
The number 91 fits into 410 4 times, leaving a remainder of 46.
Record the quotient 4 as the next digit in the result. 
Result so far: 229436.4505494
If we take 364 away from 410, we end up with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Moving on to step 16:
91 goes into 460 5 times with a remainder of 5.
Put 5 as the next digit of the answer. 
Result so far: 229436.45054945
If we subtract 455 from 460, we get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Our division results in 229436.45054945 with a remaining 5e-09.
