769737 divided by 21 
We're looking to find how many times 21 goes into 769737.

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
Subtracting 0 from 7 leaves us with 7.
Grab the next digit (6) from the dividend, add it to 7, then carry on: 76 / 21

Advancing to step 2:
If we divide 76 by 21, we get 3 and a remainder of 13.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
Subtracting 63 from 76 leaves us with 13.
Include the next digit (9) from the dividend after 13, then repeat: 139 / 21

Step 3:
21 can be fit into 139 6 times, resulting in a remainder of 13.
The next digit of our result is 6. 
Result so far: 36.0
If we take 126 away from 139, we end up with 13.
Fetch the next digit (7) from the dividend, attach it to 13 and continue: 137 / 21

Let's proceed to step 4:
The number 21 fits into 137 6 times, leaving a remainder of 11.
Record the quotient 6 as the next digit in the result. 
Result so far: 366.0
Deduct 126 from 137 and we're left with 11.
Fetch the next digit (3) from the dividend, attach it to 11 and continue: 113 / 21

Step 5:
113 divided by 21 is 5 with a remainder of 8.
Put 5 as the next digit of the answer. 
Result so far: 3665.0
Subtract 105 from 113 to get 8.
Include the next digit (7) from the dividend after 8, then repeat: 87 / 21

Moving on to step 6:
If we divide 87 by 21, we get 4 and a remainder of 3.
Put 4 as the next digit of the answer. 
Result so far: 36654.0
Deduct 84 from 87 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.

Let's proceed to step 7:
When dividing 30 by 21, we get 1 with a remainder of 9.
Record the quotient 1 as the next digit in the result. 
Result so far: 36654.1
If we subtract 21 from 30, we 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.

Let's proceed to step 8:
If we divide 90 by 21, we get 4 and a remainder of 6.
Write down 4 as next digit of the result. 
Result so far: 36654.14
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.

Let's proceed to step 9:
21 goes into 60 2 times with a remainder of 18.
Use 2 as the next digit of our solution. 
Result so far: 36654.142
The remainder is 18 after subtracting 42 from 60.
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 10:
180 divided by 21 is 8 with a remainder of 12.
Use 8 as the next digit of our solution. 
Result so far: 36654.1428
Subtract 168 from 180 to get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Advancing to step 11:
If we divide 120 by 21, we get 5 and a remainder of 15.
The number 5 becomes the next digit in our result. 
Result so far: 36654.14285
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.

Step 12:
150 divided by 21 is 7 with a remainder of 3.
Put 7 as the next digit of the answer. 
Result so far: 36654.142857
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.

Let's proceed to step 13:
The number 21 fits into 30 1 times, leaving a remainder of 9.
Record the quotient 1 as the next digit in the result. 
Result so far: 36654.1428571
If we take 21 away from 30, we end up 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.

On to step 14:
21 goes into 90 4 times with a remainder of 6.
The next digit of our result is 4. 
Result so far: 36654.14285714
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.

The quotient of the division is 36654.14285714, and the remainder is 6e-09.
