Let's divide 763422 by 21
We're looking to find how many times 21 goes into 763422.

Let's proceed to step 1:
The number 21 fits into 7 0 times, leaving a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Include the next digit (6) from the dividend after 7, then repeat: 76 / 21

Going ahead to step 2:
The number 21 fits into 76 3 times, leaving a remainder of 13.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
Deduct 63 from 76 and we're left with 13.
Include the next digit (3) from the dividend after 13, then repeat: 133 / 21

Going ahead to step 3:
If we divide 133 by 21, we get 6 and a remainder of 7.
Put 6 as the next digit of the answer. 
Result so far: 36.0
If we subtract 126 from 133, we get 7.
Grab the next digit (4) from the dividend, add it to 7, then carry on: 74 / 21

Step 4:
When dividing 74 by 21, we get 3 with a remainder of 11.
Write down 3 as next digit of the result. 
Result so far: 363.0
Deduct 63 from 74 and we're left with 11.
Take the next digit (2) from the dividend and append it to 11, then repeat: 112 / 21

Going ahead to step 5:
When dividing 112 by 21, we get 5 with a remainder of 7.
Put 5 as the next digit of the answer. 
Result so far: 3635.0
Deduct 105 from 112 and we're left with 7.
Bring next digit (2) of the dividend behind the 7 and repeat the process: 72 / 21

Advancing to step 6:
72 divided by 21 is 3 with a remainder of 9.
Write down 3 as next digit of the result. 
Result so far: 36353.0
The remainder is 9 after subtracting 63 from 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Advancing to step 7:
If we divide 90 by 21, we get 4 and a remainder of 6.
The next digit of our result is 4. 
Result so far: 36353.4
Deduct 84 from 90 and we're left with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Moving on to step 8:
21 goes into 60 2 times with a remainder of 18.
The number 2 becomes the next digit in our result. 
Result so far: 36353.42
If we take 42 away from 60, we end up with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Going ahead to step 9:
If we divide 180 by 21, we get 8 and a remainder of 12.
Put 8 as the next digit of the answer. 
Result so far: 36353.428
Subtracting 168 from 180 leaves us with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Step 10:
When dividing 120 by 21, we get 5 with a remainder of 15.
Write down 5 as next digit of the result. 
Result so far: 36353.4285
If we subtract 105 from 120, we get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Let's proceed to step 11:
When dividing 150 by 21, we get 7 with a remainder of 3.
Use 7 as the next digit of our solution. 
Result so far: 36353.42857
Deduct 147 from 150 and we're left with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Going ahead to step 12:
If we divide 30 by 21, we get 1 and a remainder of 9.
Use 1 as the next digit of our solution. 
Result so far: 36353.428571
Subtracting 21 from 30 leaves us with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Going ahead to step 13:
21 can be fit into 90 4 times, resulting in a remainder of 6.
Record the quotient 4 as the next digit in the result. 
Result so far: 36353.4285714
Subtracting 84 from 90 leaves us with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Advancing to step 14:
60 divided by 21 is 2 with a remainder of 18.
Record the quotient 2 as the next digit in the result. 
Result so far: 36353.42857142
Subtract 42 from 60 to get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Our division results in 36353.42857142 with a remaining 1.8e-08.
