181917 divided by 21 
We want to divide 181917 by 21.

Going ahead to step 1:
21 can be fit into 1 0 times, resulting in a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Take the next digit (8) from the dividend and append it to 1, then repeat: 18 / 21

Going ahead to step 2:
If we divide 18 by 21, we get 0 and a remainder of 18.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 18 leaves us with 18.
Include the next digit (1) from the dividend after 18, then repeat: 181 / 21

Going ahead to step 3:
When dividing 181 by 21, we get 8 with a remainder of 13.
The next digit of our result is 8. 
Result so far: 8.0
If we subtract 168 from 181, we get 13.
Fetch the next digit (9) from the dividend, attach it to 13 and continue: 139 / 21

Advancing to step 4:
The number 21 fits into 139 6 times, leaving a remainder of 13.
The next digit of our result is 6. 
Result so far: 86.0
Subtracting 126 from 139 leaves us with 13.
Append the next digit (1) from the dividend to 13 and continue with: 131 / 21

Moving on to step 5:
The number 21 fits into 131 6 times, leaving a remainder of 5.
Record the quotient 6 as the next digit in the result. 
Result so far: 866.0
Deduct 126 from 131 and we're left with 5.
Include the next digit (7) from the dividend after 5, then repeat: 57 / 21

On to step 6:
21 can be fit into 57 2 times, resulting in a remainder of 15.
Write down 2 as next digit of the result. 
Result so far: 8662.0
Deduct 42 from 57 and we're left with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

On to step 7:
21 can be fit into 150 7 times, resulting in a remainder of 3.
The next digit of our result is 7. 
Result so far: 8662.7
The remainder is 3 after subtracting 147 from 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Advancing to step 8:
21 goes into 30 1 times with a remainder of 9.
Use 1 as the next digit of our solution. 
Result so far: 8662.71
Subtract 21 from 30 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.

Going ahead to step 9:
If we divide 90 by 21, we get 4 and a remainder of 6.
Write down 4 as next digit of the result. 
Result so far: 8662.714
Subtract 84 from 90 to get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Advancing to step 10:
When dividing 60 by 21, we get 2 with a remainder of 18.
The number 2 becomes the next digit in our result. 
Result so far: 8662.7142
Deduct 42 from 60 and we're left with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Moving on to step 11:
21 can be fit into 180 8 times, resulting in a remainder of 12.
Write down 8 as next digit of the result. 
Result so far: 8662.71428
The remainder is 12 after subtracting 168 from 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Advancing to step 12:
120 divided by 21 is 5 with a remainder of 15.
Put 5 as the next digit of the answer. 
Result so far: 8662.714285
If we subtract 105 from 120, we get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Step 13:
If we divide 150 by 21, we get 7 and a remainder of 3.
The number 7 becomes the next digit in our result. 
Result so far: 8662.7142857
Subtract 147 from 150 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 14:
21 goes into 30 1 times with a remainder of 9.
Put 1 as the next digit of the answer. 
Result so far: 8662.71428571
Deduct 21 from 30 and we're left with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

The quotient of the division is 8662.71428571, and the remainder is 9e-09.
