We're dividing 19812820 by 91 
Our goal is to divide 19812820 by 91.

Advancing to step 1:
When dividing 1 by 91, we get 0 with 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.
Append the next digit (9) from the dividend to 1 and continue with: 19 / 91

Going ahead to step 2:
If we divide 19 by 91, we get 0 and a remainder of 19.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 19 after subtracting 0 from 19.
Fetch the next digit (8) from the dividend, attach it to 19 and continue: 198 / 91

On to step 3:
198 divided by 91 is 2 with a remainder of 16.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
Deduct 182 from 198 and we're left with 16.
Take the next digit (1) from the dividend and append it to 16, then repeat: 161 / 91

On to step 4:
91 goes into 161 1 times with a remainder of 70.
Write down 1 as next digit of the result. 
Result so far: 21.0
Subtracting 91 from 161 leaves us with 70.
Bring next digit (2) of the dividend behind the 70 and repeat the process: 702 / 91

Advancing to step 5:
91 goes into 702 7 times with a remainder of 65.
Record the quotient 7 as the next digit in the result. 
Result so far: 217.0
Subtract 637 from 702 to get 65.
Fetch the next digit (8) from the dividend, attach it to 65 and continue: 658 / 91

Going ahead to step 6:
When dividing 658 by 91, we get 7 with a remainder of 21.
Use 7 as the next digit of our solution. 
Result so far: 2177.0
If we take 637 away from 658, we end up with 21.
Include the next digit (2) from the dividend after 21, then repeat: 212 / 91

Let's proceed to step 7:
91 goes into 212 2 times with a remainder of 30.
The number 2 becomes the next digit in our result. 
Result so far: 21772.0
The remainder is 30 after subtracting 182 from 212.
Grab the next digit (0) from the dividend, add it to 30, then carry on: 300 / 91

Advancing to step 8:
91 can be fit into 300 3 times, resulting in a remainder of 27.
Write down 3 as next digit of the result. 
Result so far: 217723.0
If we subtract 273 from 300, we get 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Moving on to step 9:
The number 91 fits into 270 2 times, leaving a remainder of 88.
Write down 2 as next digit of the result. 
Result so far: 217723.2
Deduct 182 from 270 and we're left 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 10:
91 can be fit into 880 9 times, resulting in a remainder of 61.
The next digit of our result is 9. 
Result so far: 217723.29
Subtract 819 from 880 to 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.

Let's proceed to step 11:
91 can be fit into 610 6 times, resulting in a remainder of 64.
The next digit of our result is 6. 
Result so far: 217723.296
If we take 546 away from 610, we end up 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.

Step 12:
640 divided by 91 is 7 with a remainder of 3.
Record the quotient 7 as the next digit in the result. 
Result so far: 217723.2967
Subtract 637 from 640 to get 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 13:
91 goes into 30 0 times with a remainder of 30.
Write down 0 as next digit of the result. 
Result so far: 217723.2967
Subtracting 0 from 30 leaves us with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Step 14:
If we divide 300 by 91, we get 3 and a remainder of 27.
Put 3 as the next digit of the answer. 
Result so far: 217723.296703
The remainder is 27 after subtracting 273 from 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Let's proceed to step 15:
91 can be fit into 270 2 times, resulting in a remainder of 88.
The number 2 becomes the next digit in our result. 
Result so far: 217723.2967032
Subtracting 182 from 270 leaves us 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.

Moving on to step 16:
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: 217723.29670329
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.

After the division, we end up with 217723.29670329 and a remainder of 6.1e-08.
