Let's divide 715166 by 21
We want to figure out the number of times 715166 can be divided by 21.

Going ahead to step 1:
If we divide 7 by 21, we get 0 and a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Grab the next digit (1) from the dividend, add it to 7, then carry on: 71 / 21

Going ahead to step 2:
71 divided by 21 is 3 with a remainder of 8.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
Deduct 63 from 71 and we're left with 8.
Append the next digit (5) from the dividend to 8 and continue with: 85 / 21

On to step 3:
85 divided by 21 is 4 with a remainder of 1.
Use 4 as the next digit of our solution. 
Result so far: 34.0
The remainder is 1 after subtracting 84 from 85.
Include the next digit (1) from the dividend after 1, then repeat: 11 / 21

Step 4:
21 can be fit into 11 0 times, resulting in a remainder of 11.
The number 0 becomes the next digit in our result. 
Result so far: 340.0
Subtract 0 from 11 to get 11.
Take the next digit (6) from the dividend and append it to 11, then repeat: 116 / 21

Step 5:
If we divide 116 by 21, we get 5 and a remainder of 11.
Record the quotient 5 as the next digit in the result. 
Result so far: 3405.0
Deduct 105 from 116 and we're left with 11.
Include the next digit (6) from the dividend after 11, then repeat: 116 / 21

Going ahead to step 6:
21 goes into 116 5 times with a remainder of 11.
Record the quotient 5 as the next digit in the result. 
Result so far: 34055.0
Subtracting 105 from 116 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.

On to step 7:
110 divided by 21 is 5 with a remainder of 5.
Put 5 as the next digit of the answer. 
Result so far: 34055.5
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 8:
21 goes into 50 2 times with a remainder of 8.
Put 2 as the next digit of the answer. 
Result so far: 34055.52
Subtracting 42 from 50 leaves us with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Advancing to step 9:
80 divided by 21 is 3 with a remainder of 17.
The number 3 becomes the next digit in our result. 
Result so far: 34055.523
If we subtract 63 from 80, we 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.

Going ahead to step 10:
170 divided by 21 is 8 with a remainder of 2.
The next digit of our result is 8. 
Result so far: 34055.5238
The remainder is 2 after subtracting 168 from 170.
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 11:
21 goes into 20 0 times with a remainder of 20.
Use 0 as the next digit of our solution. 
Result so far: 34055.5238
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.

Let's proceed to step 12:
When dividing 200 by 21, we get 9 with a remainder of 11.
Write down 9 as next digit of the result. 
Result so far: 34055.523809
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.

Let's proceed to step 13:
When dividing 110 by 21, we get 5 with a remainder of 5.
Put 5 as the next digit of the answer. 
Result so far: 34055.5238095
The remainder is 5 after subtracting 105 from 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Let's proceed to step 14:
21 can be fit into 50 2 times, resulting in a remainder of 8.
Write down 2 as next digit of the result. 
Result so far: 34055.52380952
Subtracting 42 from 50 leaves us with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

The final result is 34055.52380952 with a remainder of 8e-09.
