Let's divide 742432 by 20
We're looking to find how many times 20 goes into 742432.

On to step 1:
20 can be fit into 7 0 times, resulting in a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Append the next digit (4) from the dividend to 7 and continue with: 74 / 20

Step 2:
20 can be fit into 74 3 times, resulting in a remainder of 14.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
The remainder is 14 after subtracting 60 from 74.
Append the next digit (2) from the dividend to 14 and continue with: 142 / 20

Let's proceed to step 3:
When dividing 142 by 20, we get 7 with a remainder of 2.
Put 7 as the next digit of the answer. 
Result so far: 37.0
Subtract 140 from 142 to get 2.
Fetch the next digit (4) from the dividend, attach it to 2 and continue: 24 / 20

Going ahead to step 4:
When dividing 24 by 20, we get 1 with a remainder of 4.
Write down 1 as next digit of the result. 
Result so far: 371.0
If we subtract 20 from 24, we get 4.
Grab the next digit (3) from the dividend, add it to 4, then carry on: 43 / 20

Let's proceed to step 5:
If we divide 43 by 20, we get 2 and a remainder of 3.
The number 2 becomes the next digit in our result. 
Result so far: 3712.0
Subtract 40 from 43 to get 3.
Bring next digit (2) of the dividend behind the 3 and repeat the process: 32 / 20

Let's proceed to step 6:
20 goes into 32 1 times with a remainder of 12.
Write down 1 as next digit of the result. 
Result so far: 37121.0
If we take 20 away from 32, we end up with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

On to step 7:
120 divided by 20 is 6 with a remainder of 0.
The number 6 becomes the next digit in our result. 
Result so far: 37121.6
The remainder is 0 after subtracting 120 from 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 8:
When dividing 0 by 20, we get 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 37121.6
If we take 0 away from 0, we end up 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 9:
20 can be fit into 0 0 times, resulting in a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 37121.6
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.

The final outcome is 37121.6, with a leftover of 0.0.
