170627 divided by 21 
We want to figure out the number of times 170627 can be divided by 21.

Advancing to step 1:
If we divide 1 by 21, we get 0 and a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Fetch the next digit (7) from the dividend, attach it to 1 and continue: 17 / 21

Moving on to step 2:
21 can be fit into 17 0 times, resulting in a remainder of 17.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 17 and we're left with 17.
Fetch the next digit (0) from the dividend, attach it to 17 and continue: 170 / 21

Advancing to step 3:
21 can be fit into 170 8 times, resulting in a remainder of 2.
The number 8 becomes the next digit in our result. 
Result so far: 8.0
Subtracting 168 from 170 leaves us with 2.
Take the next digit (6) from the dividend and append it to 2, then repeat: 26 / 21

Moving on to step 4:
21 can be fit into 26 1 times, resulting in a remainder of 5.
Record the quotient 1 as the next digit in the result. 
Result so far: 81.0
Subtracting 21 from 26 leaves us with 5.
Grab the next digit (2) from the dividend, add it to 5, then carry on: 52 / 21

On to step 5:
The number 21 fits into 52 2 times, leaving a remainder of 10.
Use 2 as the next digit of our solution. 
Result so far: 812.0
The remainder is 10 after subtracting 42 from 52.
Grab the next digit (7) from the dividend, add it to 10, then carry on: 107 / 21

Advancing to step 6:
When dividing 107 by 21, we get 5 with a remainder of 2.
The number 5 becomes the next digit in our result. 
Result so far: 8125.0
The remainder is 2 after subtracting 105 from 107.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Advancing to step 7:
If we divide 20 by 21, we get 0 and a remainder of 20.
Put 0 as the next digit of the answer. 
Result so far: 8125.0
If we subtract 0 from 20, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Going ahead to step 8:
21 can be fit into 200 9 times, resulting in a remainder of 11.
The next digit of our result is 9. 
Result so far: 8125.09
Subtracting 189 from 200 leaves us with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Step 9:
The number 21 fits into 110 5 times, leaving a remainder of 5.
Record the quotient 5 as the next digit in the result. 
Result so far: 8125.095
If we take 105 away from 110, we end up with 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 10:
21 goes into 50 2 times with a remainder of 8.
Record the quotient 2 as the next digit in the result. 
Result so far: 8125.0952
If we subtract 42 from 50, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Going ahead to step 11:
When dividing 80 by 21, we get 3 with a remainder of 17.
Use 3 as the next digit of our solution. 
Result so far: 8125.09523
Subtract 63 from 80 to get 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Step 12:
170 divided by 21 is 8 with a remainder of 2.
Use 8 as the next digit of our solution. 
Result so far: 8125.095238
If we take 168 away from 170, we end up with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Advancing to step 13:
When dividing 20 by 21, we get 0 with a remainder of 20.
Use 0 as the next digit of our solution. 
Result so far: 8125.095238
If we subtract 0 from 20, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

On to step 14:
200 divided by 21 is 9 with a remainder of 11.
The number 9 becomes the next digit in our result. 
Result so far: 8125.09523809
The remainder is 11 after subtracting 189 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Our division results in 8125.09523809 with a remaining 1.1e-08.
