761945 ÷ 21 
We want to figure out the number of times 761945 can be divided by 21.

Going ahead 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.
Grab the next digit (6) from the dividend, add it to 7, then carry on: 76 / 21

Let's proceed to step 2:
The number 21 fits into 76 3 times, leaving a remainder of 13.
Put 3 as the next digit of the answer. 
Result so far: 3.0
If we subtract 63 from 76, we get 13.
Include the next digit (1) from the dividend after 13, then repeat: 131 / 21

Moving on to step 3:
When dividing 131 by 21, we get 6 with a remainder of 5.
The next digit of our result is 6. 
Result so far: 36.0
The remainder is 5 after subtracting 126 from 131.
Grab the next digit (9) from the dividend, add it to 5, then carry on: 59 / 21

Moving on to step 4:
21 goes into 59 2 times with a remainder of 17.
The next digit of our result is 2. 
Result so far: 362.0
If we take 42 away from 59, we end up with 17.
Fetch the next digit (4) from the dividend, attach it to 17 and continue: 174 / 21

Advancing to step 5:
If we divide 174 by 21, we get 8 and a remainder of 6.
Put 8 as the next digit of the answer. 
Result so far: 3628.0
Deduct 168 from 174 and we're left with 6.
Bring next digit (5) of the dividend behind the 6 and repeat the process: 65 / 21

Step 6:
When dividing 65 by 21, we get 3 with a remainder of 2.
The number 3 becomes the next digit in our result. 
Result so far: 36283.0
The remainder is 2 after subtracting 63 from 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Advancing to step 7:
20 divided by 21 is 0 with a remainder of 20.
Write down 0 as next digit of the result. 
Result so far: 36283.0
Subtracting 0 from 20 leaves us with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Going ahead to step 8:
The number 21 fits into 200 9 times, leaving a remainder of 11.
Write down 9 as next digit of the result. 
Result so far: 36283.09
If we subtract 189 from 200, 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:
110 divided by 21 is 5 with a remainder of 5.
Use 5 as the next digit of our solution. 
Result so far: 36283.095
Subtracting 105 from 110 leaves us 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.

On to step 10:
When dividing 50 by 21, we get 2 with a remainder of 8.
The next digit of our result is 2. 
Result so far: 36283.0952
If we take 42 away from 50, we end up 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.

Moving 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: 36283.09523
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.

On to step 12:
When dividing 170 by 21, we get 8 with a remainder of 2.
Record the quotient 8 as the next digit in the result. 
Result so far: 36283.095238
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.

Advancing to step 13:
The number 21 fits into 20 0 times, leaving a remainder of 20.
The next digit of our result is 0. 
Result so far: 36283.095238
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.

Let's proceed to step 14:
200 divided by 21 is 9 with a remainder of 11.
Record the quotient 9 as the next digit in the result. 
Result so far: 36283.09523809
Subtracting 189 from 200 leaves us with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

The quotient of the division is 36283.09523809, and the remainder is 1.1e-08.
