Let's divide 79779808 by 138
Our goal is to divide 79779808 by 138.

Let's proceed to step 1:
The number 138 fits into 7 0 times, leaving a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Take the next digit (9) from the dividend and append it to 7, then repeat: 79 / 138

Let's proceed to step 2:
The number 138 fits into 79 0 times, leaving a remainder of 79.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 79, we end up with 79.
Append the next digit (7) from the dividend to 79 and continue with: 797 / 138

Going ahead to step 3:
138 can be fit into 797 5 times, resulting in a remainder of 107.
Put 5 as the next digit of the answer. 
Result so far: 5.0
Deduct 690 from 797 and we're left with 107.
Include the next digit (7) from the dividend after 107, then repeat: 1077 / 138

Let's proceed to step 4:
138 goes into 1077 7 times with a remainder of 111.
Put 7 as the next digit of the answer. 
Result so far: 57.0
Subtract 966 from 1077 to get 111.
Fetch the next digit (9) from the dividend, attach it to 111 and continue: 1119 / 138

Let's proceed to step 5:
If we divide 1119 by 138, we get 8 and a remainder of 15.
Use 8 as the next digit of our solution. 
Result so far: 578.0
If we take 1104 away from 1119, we end up with 15.
Take the next digit (8) from the dividend and append it to 15, then repeat: 158 / 138

Advancing to step 6:
The number 138 fits into 158 1 times, leaving a remainder of 20.
Write down 1 as next digit of the result. 
Result so far: 5781.0
Subtracting 138 from 158 leaves us with 20.
Bring next digit (0) of the dividend behind the 20 and repeat the process: 200 / 138

Let's proceed to step 7:
When dividing 200 by 138, we get 1 with a remainder of 62.
Record the quotient 1 as the next digit in the result. 
Result so far: 57811.0
Deduct 138 from 200 and we're left with 62.
Take the next digit (8) from the dividend and append it to 62, then repeat: 628 / 138

Step 8:
138 goes into 628 4 times with a remainder of 76.
Put 4 as the next digit of the answer. 
Result so far: 578114.0
If we take 552 away from 628, we end up with 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Advancing to step 9:
138 can be fit into 760 5 times, resulting in a remainder of 70.
Record the quotient 5 as the next digit in the result. 
Result so far: 578114.5
Deduct 690 from 760 and we're left with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Advancing to step 10:
700 divided by 138 is 5 with a remainder of 10.
Put 5 as the next digit of the answer. 
Result so far: 578114.55
If we take 690 away from 700, 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.

In conclusion, the division gives 578114.55 with a balance of 0.01.
