We divide 775406 by 21
Let's see how many times 21 fits into 775406.

Let's proceed to step 1:
If we divide 7 by 21, we get 0 and a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Grab the next digit (7) from the dividend, add it to 7, then carry on: 77 / 21

Moving on to step 2:
When dividing 77 by 21, we get 3 with a remainder of 14.
The next digit of our result is 3. 
Result so far: 3.0
Deduct 63 from 77 and we're left with 14.
Grab the next digit (5) from the dividend, add it to 14, then carry on: 145 / 21

Moving on to step 3:
145 divided by 21 is 6 with a remainder of 19.
Write down 6 as next digit of the result. 
Result so far: 36.0
Subtracting 126 from 145 leaves us with 19.
Take the next digit (4) from the dividend and append it to 19, then repeat: 194 / 21

On to step 4:
21 goes into 194 9 times with a remainder of 5.
Write down 9 as next digit of the result. 
Result so far: 369.0
Deduct 189 from 194 and we're left with 5.
Take the next digit (0) from the dividend and append it to 5, then repeat: 50 / 21

Step 5:
The number 21 fits into 50 2 times, leaving a remainder of 8.
Record the quotient 2 as the next digit in the result. 
Result so far: 3692.0
If we take 42 away from 50, we end up with 8.
Append the next digit (6) from the dividend to 8 and continue with: 86 / 21

Let's proceed to step 6:
21 goes into 86 4 times with a remainder of 2.
Use 4 as the next digit of our solution. 
Result so far: 36924.0
Subtracting 84 from 86 leaves us 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.

On to step 7:
The number 21 fits into 20 0 times, leaving a remainder of 20.
The number 0 becomes the next digit in our result. 
Result so far: 36924.0
Subtract 0 from 20 to 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.

Step 8:
21 goes into 200 9 times with a remainder of 11.
Write down 9 as next digit of the result. 
Result so far: 36924.09
If we take 189 away from 200, we end up 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 9:
If we divide 110 by 21, we get 5 and a remainder of 5.
Use 5 as the next digit of our solution. 
Result so far: 36924.095
Deduct 105 from 110 and we're left 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.

Step 10:
When dividing 50 by 21, we get 2 with a remainder of 8.
Use 2 as the next digit of our solution. 
Result so far: 36924.0952
The remainder is 8 after subtracting 42 from 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Moving on to step 11:
21 can be fit into 80 3 times, resulting in a remainder of 17.
Record the quotient 3 as the next digit in the result. 
Result so far: 36924.09523
The remainder is 17 after subtracting 63 from 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

On to step 12:
170 divided by 21 is 8 with a remainder of 2.
Record the quotient 8 as the next digit in the result. 
Result so far: 36924.095238
Subtract 168 from 170 to get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Going ahead to step 13:
20 divided by 21 is 0 with a remainder of 20.
Use 0 as the next digit of our solution. 
Result so far: 36924.095238
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.

Step 14:
When dividing 200 by 21, we get 9 with a remainder of 11.
Put 9 as the next digit of the answer. 
Result so far: 36924.09523809
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 36924.09523809 with a remaining 1.1e-08.
