Let's divide 749946 by 20
Let's see how many times 20 fits into 749946.

Going ahead to step 1:
The number 20 fits into 7 0 times, leaving a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Include the next digit (4) from the dividend after 7, then repeat: 74 / 20

Advancing to step 2:
When dividing 74 by 20, we get 3 with a remainder of 14.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
If we take 60 away from 74, we end up with 14.
Include the next digit (9) from the dividend after 14, then repeat: 149 / 20

Step 3:
20 goes into 149 7 times with a remainder of 9.
Record the quotient 7 as the next digit in the result. 
Result so far: 37.0
If we subtract 140 from 149, we get 9.
Include the next digit (9) from the dividend after 9, then repeat: 99 / 20

Let's proceed to step 4:
When dividing 99 by 20, we get 4 with a remainder of 19.
Use 4 as the next digit of our solution. 
Result so far: 374.0
Subtracting 80 from 99 leaves us with 19.
Append the next digit (4) from the dividend to 19 and continue with: 194 / 20

Step 5:
When dividing 194 by 20, we get 9 with a remainder of 14.
The next digit of our result is 9. 
Result so far: 3749.0
If we subtract 180 from 194, we get 14.
Append the next digit (6) from the dividend to 14 and continue with: 146 / 20

Advancing to step 6:
If we divide 146 by 20, we get 7 and a remainder of 6.
The number 7 becomes the next digit in our result. 
Result so far: 37497.0
If we subtract 140 from 146, we 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 7:
If we divide 60 by 20, we get 3 and a remainder of 0.
The number 3 becomes the next digit in our result. 
Result so far: 37497.3
The remainder is 0 after subtracting 60 from 60.
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 8:
20 can be fit into 0 0 times, resulting in a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 37497.3
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.

Moving 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: 37497.3
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.

The final outcome is 37497.3, with a leftover of 0.0.
