We're dividing 773954 by 21 
Let's see how many times 21 fits into 773954.

Moving on to step 1:
7 divided by 21 is 0 with a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Take the next digit (7) from the dividend and append it to 7, then repeat: 77 / 21

Going ahead to step 2:
21 can be fit into 77 3 times, resulting in a remainder of 14.
Write down 3 as next digit of the result. 
Result so far: 3.0
If we take 63 away from 77, we end up with 14.
Grab the next digit (3) from the dividend, add it to 14, then carry on: 143 / 21

Step 3:
If we divide 143 by 21, we get 6 and a remainder of 17.
The next digit of our result is 6. 
Result so far: 36.0
Subtract 126 from 143 to get 17.
Append the next digit (9) from the dividend to 17 and continue with: 179 / 21

Moving on to step 4:
When dividing 179 by 21, we get 8 with a remainder of 11.
Put 8 as the next digit of the answer. 
Result so far: 368.0
Subtracting 168 from 179 leaves us with 11.
Append the next digit (5) from the dividend to 11 and continue with: 115 / 21

Advancing to step 5:
If we divide 115 by 21, we get 5 and a remainder of 10.
Put 5 as the next digit of the answer. 
Result so far: 3685.0
If we take 105 away from 115, we end up with 10.
Take the next digit (4) from the dividend and append it to 10, then repeat: 104 / 21

Let's proceed to step 6:
21 goes into 104 4 times with a remainder of 20.
The number 4 becomes the next digit in our result. 
Result so far: 36854.0
The remainder is 20 after subtracting 84 from 104.
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 7:
21 goes into 200 9 times with a remainder of 11.
Record the quotient 9 as the next digit in the result. 
Result so far: 36854.9
Subtract 189 from 200 to get 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 8:
21 can be fit into 110 5 times, resulting in a remainder of 5.
Write down 5 as next digit of the result. 
Result so far: 36854.95
If we subtract 105 from 110, we get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Advancing to step 9:
The number 21 fits into 50 2 times, leaving a remainder of 8.
Put 2 as the next digit of the answer. 
Result so far: 36854.952
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.

Going ahead to step 10:
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: 36854.9523
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.

Moving on to step 11:
If we divide 170 by 21, we get 8 and a remainder of 2.
Record the quotient 8 as the next digit in the result. 
Result so far: 36854.95238
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.

Step 12:
20 divided by 21 is 0 with a remainder of 20.
Record the quotient 0 as the next digit in the result. 
Result so far: 36854.95238
The remainder is 20 after subtracting 0 from 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 13:
The number 21 fits into 200 9 times, leaving a remainder of 11.
The next digit of our result is 9. 
Result so far: 36854.9523809
Subtract 189 from 200 to get 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 14:
110 divided by 21 is 5 with a remainder of 5.
The number 5 becomes the next digit in our result. 
Result so far: 36854.95238095
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.

Our division results in 36854.95238095 with a remaining 5e-09.
