76711289 ÷ 21 
We want to divide 76711289 by 21.

Let's proceed to step 1:
21 can be fit into 7 0 times, resulting in a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Append the next digit (6) from the dividend to 7 and continue with: 76 / 21

On to step 2:
When dividing 76 by 21, we get 3 with a remainder of 13.
Put 3 as the next digit of the answer. 
Result so far: 3.0
Subtract 63 from 76 to get 13.
Grab the next digit (7) from the dividend, add it to 13, then carry on: 137 / 21

Let's proceed to step 3:
21 goes into 137 6 times with a remainder of 11.
The number 6 becomes the next digit in our result. 
Result so far: 36.0
If we subtract 126 from 137, we get 11.
Append the next digit (1) from the dividend to 11 and continue with: 111 / 21

Advancing to step 4:
When dividing 111 by 21, we get 5 with a remainder of 6.
Write down 5 as next digit of the result. 
Result so far: 365.0
The remainder is 6 after subtracting 105 from 111.
Bring next digit (1) of the dividend behind the 6 and repeat the process: 61 / 21

Moving on to step 5:
When dividing 61 by 21, we get 2 with a remainder of 19.
Use 2 as the next digit of our solution. 
Result so far: 3652.0
Deduct 42 from 61 and we're left with 19.
Bring next digit (2) of the dividend behind the 19 and repeat the process: 192 / 21

Moving on to step 6:
The number 21 fits into 192 9 times, leaving a remainder of 3.
Record the quotient 9 as the next digit in the result. 
Result so far: 36529.0
Subtract 189 from 192 to get 3.
Include the next digit (8) from the dividend after 3, then repeat: 38 / 21

Step 7:
The number 21 fits into 38 1 times, leaving a remainder of 17.
Put 1 as the next digit of the answer. 
Result so far: 365291.0
Subtracting 21 from 38 leaves us with 17.
Bring next digit (9) of the dividend behind the 17 and repeat the process: 179 / 21

Going ahead to step 8:
21 goes into 179 8 times with a remainder of 11.
The next digit of our result is 8. 
Result so far: 3652918.0
If we subtract 168 from 179, we 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.

Let's proceed to step 9:
The number 21 fits into 110 5 times, leaving a remainder of 5.
Use 5 as the next digit of our solution. 
Result so far: 3652918.5
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.

Let's proceed to step 10:
50 divided by 21 is 2 with a remainder of 8.
Put 2 as the next digit of the answer. 
Result so far: 3652918.52
Deduct 42 from 50 and we're left 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.

On to step 11:
80 divided by 21 is 3 with a remainder of 17.
Use 3 as the next digit of our solution. 
Result so far: 3652918.523
Subtract 63 from 80 to 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.

Advancing to step 12:
When dividing 170 by 21, we get 8 with a remainder of 2.
Write down 8 as next digit of the result. 
Result so far: 3652918.5238
Subtracting 168 from 170 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.

Let's proceed to step 13:
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: 3652918.5238
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.

Moving on to step 14:
21 can be fit into 200 9 times, resulting in a remainder of 11.
Put 9 as the next digit of the answer. 
Result so far: 3652918.523809
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.

Going ahead to step 15:
If we divide 110 by 21, we get 5 and a remainder of 5.
Record the quotient 5 as the next digit in the result. 
Result so far: 3652918.5238095
Subtract 105 from 110 to 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.

Let's proceed to step 16:
If we divide 50 by 21, we get 2 and a remainder of 8.
The next digit of our result is 2. 
Result so far: 3652918.52380952
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.

The quotient of the division is 3652918.52380952, and the remainder is 8e-09.
