We divide 779539 by 21
Let's see how many times 21 fits into 779539.

Step 1:
If we divide 7 by 21, we get 0 and a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Fetch the next digit (7) from the dividend, attach it to 7 and continue: 77 / 21

Moving on to step 2:
The number 21 fits into 77 3 times, leaving a remainder of 14.
Put 3 as the next digit of the answer. 
Result so far: 3.0
Deduct 63 from 77 and we're left with 14.
Grab the next digit (9) from the dividend, add it to 14, then carry on: 149 / 21

On to step 3:
When dividing 149 by 21, we get 7 with a remainder of 2.
The number 7 becomes the next digit in our result. 
Result so far: 37.0
If we take 147 away from 149, we end up with 2.
Include the next digit (5) from the dividend after 2, then repeat: 25 / 21

Advancing to step 4:
If we divide 25 by 21, we get 1 and a remainder of 4.
The next digit of our result is 1. 
Result so far: 371.0
If we take 21 away from 25, we end up with 4.
Append the next digit (3) from the dividend to 4 and continue with: 43 / 21

Let's proceed to step 5:
If we divide 43 by 21, we get 2 and a remainder of 1.
Write down 2 as next digit of the result. 
Result so far: 3712.0
Subtracting 42 from 43 leaves us with 1.
Take the next digit (9) from the dividend and append it to 1, then repeat: 19 / 21

Let's proceed to step 6:
When dividing 19 by 21, we get 0 with a remainder of 19.
The next digit of our result is 0. 
Result so far: 37120.0
If we subtract 0 from 19, we get 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Let's proceed to step 7:
190 divided by 21 is 9 with a remainder of 1.
Use 9 as the next digit of our solution. 
Result so far: 37120.9
Subtract 189 from 190 to get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Moving on to step 8:
If we divide 10 by 21, we get 0 and a remainder of 10.
Write down 0 as next digit of the result. 
Result so far: 37120.9
If we subtract 0 from 10, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 9:
If we divide 100 by 21, we get 4 and a remainder of 16.
Use 4 as the next digit of our solution. 
Result so far: 37120.904
Subtracting 84 from 100 leaves us with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Advancing to step 10:
160 divided by 21 is 7 with a remainder of 13.
Put 7 as the next digit of the answer. 
Result so far: 37120.9047
If we subtract 147 from 160, we get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

On to step 11:
21 goes into 130 6 times with a remainder of 4.
Record the quotient 6 as the next digit in the result. 
Result so far: 37120.90476
If we take 126 away from 130, we end up with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

On to step 12:
When dividing 40 by 21, we get 1 with a remainder of 19.
Use 1 as the next digit of our solution. 
Result so far: 37120.904761
Subtract 21 from 40 to get 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Let's proceed to step 13:
The number 21 fits into 190 9 times, leaving a remainder of 1.
Use 9 as the next digit of our solution. 
Result so far: 37120.9047619
Subtracting 189 from 190 leaves us with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Going ahead to step 14:
21 goes into 10 0 times with a remainder of 10.
The number 0 becomes the next digit in our result. 
Result so far: 37120.9047619
If we take 0 away from 10, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

The quotient of the division is 37120.9047619, and the remainder is 1e-08.
