72747196 ÷ 20 
Our goal is to divide 72747196 by 20.

Step 1:
If we divide 7 by 20, we get 0 and a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Take the next digit (2) from the dividend and append it to 7, then repeat: 72 / 20

On to step 2:
The number 20 fits into 72 3 times, leaving a remainder of 12.
Write down 3 as next digit of the result. 
Result so far: 3.0
Deduct 60 from 72 and we're left with 12.
Grab the next digit (7) from the dividend, add it to 12, then carry on: 127 / 20

Moving on to step 3:
20 goes into 127 6 times with a remainder of 7.
Put 6 as the next digit of the answer. 
Result so far: 36.0
If we subtract 120 from 127, we get 7.
Fetch the next digit (4) from the dividend, attach it to 7 and continue: 74 / 20

Going ahead to step 4:
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: 363.0
Subtracting 60 from 74 leaves us with 14.
Take the next digit (7) from the dividend and append it to 14, then repeat: 147 / 20

Advancing to step 5:
When dividing 147 by 20, we get 7 with a remainder of 7.
The next digit of our result is 7. 
Result so far: 3637.0
Subtract 140 from 147 to get 7.
Take the next digit (1) from the dividend and append it to 7, then repeat: 71 / 20

Advancing to step 6:
20 can be fit into 71 3 times, resulting in a remainder of 11.
Put 3 as the next digit of the answer. 
Result so far: 36373.0
Deduct 60 from 71 and we're left with 11.
Bring next digit (9) of the dividend behind the 11 and repeat the process: 119 / 20

On to step 7:
20 can be fit into 119 5 times, resulting in a remainder of 19.
Put 5 as the next digit of the answer. 
Result so far: 363735.0
The remainder is 19 after subtracting 100 from 119.
Append the next digit (6) from the dividend to 19 and continue with: 196 / 20

Going ahead to step 8:
196 divided by 20 is 9 with a remainder of 16.
The next digit of our result is 9. 
Result so far: 3637359.0
If we take 180 away from 196, we end up with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Moving on to step 9:
20 can be fit into 160 8 times, resulting in a remainder of 0.
Write down 8 as next digit of the result. 
Result so far: 3637359.8
Subtract 160 from 160 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.

Let's proceed to step 10:
20 can be fit into 0 0 times, resulting in a remainder of 0.
The next digit of our result is 0. 
Result so far: 3637359.8
If we subtract 0 from 0, we 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.

Advancing to step 11:
20 goes into 0 0 times with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 3637359.8
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 3637359.8, with a leftover of 0.0.
