We divide 79394 by 20
Let's see how many times 20 fits into 79394.

Going ahead to step 1:
20 goes into 7 0 times with a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Fetch the next digit (9) from the dividend, attach it to 7 and continue: 79 / 20

Let's proceed to step 2:
79 divided by 20 is 3 with a remainder of 19.
Write down 3 as next digit of the result. 
Result so far: 3.0
Subtracting 60 from 79 leaves us with 19.
Bring next digit (3) of the dividend behind the 19 and repeat the process: 193 / 20

Step 3:
193 divided by 20 is 9 with a remainder of 13.
Record the quotient 9 as the next digit in the result. 
Result so far: 39.0
Deduct 180 from 193 and we're left with 13.
Bring next digit (9) of the dividend behind the 13 and repeat the process: 139 / 20

Advancing to step 4:
If we divide 139 by 20, we get 6 and a remainder of 19.
Record the quotient 6 as the next digit in the result. 
Result so far: 396.0
If we subtract 120 from 139, we get 19.
Fetch the next digit (4) from the dividend, attach it to 19 and continue: 194 / 20

Advancing to step 5:
The number 20 fits into 194 9 times, leaving a remainder of 14.
Use 9 as the next digit of our solution. 
Result so far: 3969.0
Subtracting 180 from 194 leaves us with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Advancing to step 6:
20 goes into 140 7 times with a remainder of 0.
Write down 7 as next digit of the result. 
Result so far: 3969.7
If we take 140 away from 140, 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.

Moving on to step 7:
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: 3969.7
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.

Moving on to step 8:
When dividing 0 by 20, we get 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 3969.7
Subtracting 0 from 0 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.

The final outcome is 3969.7, with a leftover of 0.0.
