Let's divide 35813795 by 21
We want to figure out the number of times 35813795 can be divided by 21.

Moving on to step 1:
21 goes into 3 0 times with a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Include the next digit (5) from the dividend after 3, then repeat: 35 / 21

Going ahead to step 2:
The number 21 fits into 35 1 times, leaving a remainder of 14.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
The remainder is 14 after subtracting 21 from 35.
Bring next digit (8) of the dividend behind the 14 and repeat the process: 148 / 21

Advancing to step 3:
If we divide 148 by 21, we get 7 and a remainder of 1.
Write down 7 as next digit of the result. 
Result so far: 17.0
Deduct 147 from 148 and we're left with 1.
Bring next digit (1) of the dividend behind the 1 and repeat the process: 11 / 21

Let's proceed to step 4:
The number 21 fits into 11 0 times, leaving a remainder of 11.
The number 0 becomes the next digit in our result. 
Result so far: 170.0
Subtracting 0 from 11 leaves us 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.
The next digit of our result is 5. 
Result so far: 1705.0
Subtract 105 from 113 to get 8.
Take the next digit (7) from the dividend and append it to 8, then repeat: 87 / 21

Step 6:
The number 21 fits into 87 4 times, leaving a remainder of 3.
Use 4 as the next digit of our solution. 
Result so far: 17054.0
Subtract 84 from 87 to get 3.
Include the next digit (9) from the dividend after 3, then repeat: 39 / 21

On to step 7:
39 divided by 21 is 1 with a remainder of 18.
Record the quotient 1 as the next digit in the result. 
Result so far: 170541.0
If we subtract 21 from 39, we get 18.
Grab the next digit (5) from the dividend, add it to 18, then carry on: 185 / 21

Let's proceed to step 8:
21 goes into 185 8 times with a remainder of 17.
Put 8 as the next digit of the answer. 
Result so far: 1705418.0
The remainder is 17 after subtracting 168 from 185.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Let's proceed to step 9:
170 divided by 21 is 8 with a remainder of 2.
The next digit of our result is 8. 
Result so far: 1705418.8
If we take 168 away from 170, we end up 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.

Moving on to step 10:
21 can be fit into 20 0 times, resulting in a remainder of 20.
Use 0 as the next digit of our solution. 
Result so far: 1705418.8
If we take 0 away from 20, we end up 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.

On to step 11:
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: 1705418.809
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 12:
If we divide 110 by 21, we get 5 and a remainder of 5.
Use 5 as the next digit of our solution. 
Result so far: 1705418.8095
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.

Moving on to step 13:
When dividing 50 by 21, we get 2 with a remainder of 8.
Use 2 as the next digit of our solution. 
Result so far: 1705418.80952
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.

On to step 14:
The number 21 fits into 80 3 times, leaving a remainder of 17.
Record the quotient 3 as the next digit in the result. 
Result so far: 1705418.809523
If we take 63 away from 80, we end up with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Step 15:
If we divide 170 by 21, we get 8 and a remainder of 2.
Write down 8 as next digit of the result. 
Result so far: 1705418.8095238
The remainder is 2 after subtracting 168 from 170.
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 16:
20 divided by 21 is 0 with a remainder of 20.
Write down 0 as next digit of the result. 
Result so far: 1705418.8095238
If we take 0 away from 20, we end up 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.

The quotient of the division is 1705418.8095238, and the remainder is 2e-08.
