761412 ÷ 21 
Our goal is to divide 761412 by 21.

Step 1:
21 can be fit into 7 0 times, resulting in a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Include the next digit (6) from the dividend after 7, then repeat: 76 / 21

Advancing to step 2:
The number 21 fits into 76 3 times, leaving a remainder of 13.
Use 3 as the next digit of our solution. 
Result so far: 3.0
If we take 63 away from 76, we end up with 13.
Bring next digit (1) of the dividend behind the 13 and repeat the process: 131 / 21

Moving on to step 3:
21 goes into 131 6 times with a remainder of 5.
The number 6 becomes the next digit in our result. 
Result so far: 36.0
The remainder is 5 after subtracting 126 from 131.
Include the next digit (4) from the dividend after 5, then repeat: 54 / 21

Let's proceed to step 4:
21 can be fit into 54 2 times, resulting in a remainder of 12.
Write down 2 as next digit of the result. 
Result so far: 362.0
If we subtract 42 from 54, we get 12.
Fetch the next digit (1) from the dividend, attach it to 12 and continue: 121 / 21

On to step 5:
21 can be fit into 121 5 times, resulting in a remainder of 16.
Put 5 as the next digit of the answer. 
Result so far: 3625.0
Subtracting 105 from 121 leaves us with 16.
Grab the next digit (2) from the dividend, add it to 16, then carry on: 162 / 21

Advancing to step 6:
If we divide 162 by 21, we get 7 and a remainder of 15.
Record the quotient 7 as the next digit in the result. 
Result so far: 36257.0
Subtracting 147 from 162 leaves us with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Going ahead to step 7:
When dividing 150 by 21, we get 7 with a remainder of 3.
Record the quotient 7 as the next digit in the result. 
Result so far: 36257.7
Subtract 147 from 150 to get 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 8:
21 can be fit into 30 1 times, resulting in a remainder of 9.
Use 1 as the next digit of our solution. 
Result so far: 36257.71
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.

Let's proceed to step 9:
The number 21 fits into 90 4 times, leaving a remainder of 6.
Write down 4 as next digit of the result. 
Result so far: 36257.714
Subtract 84 from 90 to get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Going ahead to step 10:
21 can be fit into 60 2 times, resulting in a remainder of 18.
Put 2 as the next digit of the answer. 
Result so far: 36257.7142
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.

Moving on to step 11:
180 divided by 21 is 8 with a remainder of 12.
The number 8 becomes the next digit in our result. 
Result so far: 36257.71428
The remainder is 12 after subtracting 168 from 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Let's proceed to step 12:
120 divided by 21 is 5 with a remainder of 15.
Use 5 as the next digit of our solution. 
Result so far: 36257.714285
Deduct 105 from 120 and we're left with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

On to step 13:
If we divide 150 by 21, we get 7 and a remainder of 3.
Record the quotient 7 as the next digit in the result. 
Result so far: 36257.7142857
Subtract 147 from 150 to get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Step 14:
When dividing 30 by 21, we get 1 with a remainder of 9.
The number 1 becomes the next digit in our result. 
Result so far: 36257.71428571
Subtract 21 from 30 to get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Our division results in 36257.71428571 with a remaining 9e-09.
