We look at the division of 21367007 by 20 
We want to divide 21367007 by 20.

Going ahead to step 1:
If we divide 2 by 20, we get 0 and a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Include the next digit (1) from the dividend after 2, then repeat: 21 / 20

Advancing to step 2:
The number 20 fits into 21 1 times, leaving a remainder of 1.
The next digit of our result is 1. 
Result so far: 1.0
If we subtract 20 from 21, we get 1.
Include the next digit (3) from the dividend after 1, then repeat: 13 / 20

Step 3:
20 goes into 13 0 times with a remainder of 13.
Write down 0 as next digit of the result. 
Result so far: 10.0
Subtract 0 from 13 to get 13.
Fetch the next digit (6) from the dividend, attach it to 13 and continue: 136 / 20

Let's proceed to step 4:
The number 20 fits into 136 6 times, leaving a remainder of 16.
The next digit of our result is 6. 
Result so far: 106.0
Deduct 120 from 136 and we're left with 16.
Grab the next digit (7) from the dividend, add it to 16, then carry on: 167 / 20

Moving on to step 5:
When dividing 167 by 20, we get 8 with a remainder of 7.
Use 8 as the next digit of our solution. 
Result so far: 1068.0
The remainder is 7 after subtracting 160 from 167.
Take the next digit (0) from the dividend and append it to 7, then repeat: 70 / 20

Moving on to step 6:
70 divided by 20 is 3 with a remainder of 10.
Record the quotient 3 as the next digit in the result. 
Result so far: 10683.0
If we take 60 away from 70, we end up with 10.
Include the next digit (0) from the dividend after 10, then repeat: 100 / 20

On to step 7:
The number 20 fits into 100 5 times, leaving a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 106835.0
The remainder is 0 after subtracting 100 from 100.
Include the next digit (7) from the dividend after 0, then repeat: 7 / 20

Let's proceed to step 8:
7 divided by 20 is 0 with a remainder of 7.
The next digit of our result is 0. 
Result so far: 1068350.0
Deduct 0 from 7 and we're left with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Going ahead to step 9:
The number 20 fits into 70 3 times, leaving a remainder of 10.
Write down 3 as next digit of the result. 
Result so far: 1068350.3
If we take 60 away from 70, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 10:
When dividing 100 by 20, we get 5 with a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 1068350.35
Subtracting 100 from 100 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 11:
When dividing 0 by 20, we get 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 1068350.35
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 12:
0 divided by 20 is 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 1068350.35
Deduct 0 from 0 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final result is 1068350.35 with a remainder of 0.0.
