78769560 divided by 138 
Our goal is to divide 78769560 by 138.

Let's proceed to step 1:
7 divided by 138 is 0 with a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Include the next digit (8) from the dividend after 7, then repeat: 78 / 138

Step 2:
If we divide 78 by 138, we get 0 and a remainder of 78.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 78 after subtracting 0 from 78.
Fetch the next digit (7) from the dividend, attach it to 78 and continue: 787 / 138

Step 3:
138 can be fit into 787 5 times, resulting in a remainder of 97.
The number 5 becomes the next digit in our result. 
Result so far: 5.0
If we take 690 away from 787, we end up with 97.
Include the next digit (6) from the dividend after 97, then repeat: 976 / 138

On to step 4:
When dividing 976 by 138, we get 7 with a remainder of 10.
Record the quotient 7 as the next digit in the result. 
Result so far: 57.0
If we subtract 966 from 976, we get 10.
Include the next digit (9) from the dividend after 10, then repeat: 109 / 138

Let's proceed to step 5:
The number 138 fits into 109 0 times, leaving a remainder of 109.
Use 0 as the next digit of our solution. 
Result so far: 570.0
Subtract 0 from 109 to get 109.
Append the next digit (5) from the dividend to 109 and continue with: 1095 / 138

Going ahead to step 6:
If we divide 1095 by 138, we get 7 and a remainder of 129.
The next digit of our result is 7. 
Result so far: 5707.0
If we take 966 away from 1095, we end up with 129.
Bring next digit (6) of the dividend behind the 129 and repeat the process: 1296 / 138

Let's proceed to step 7:
138 goes into 1296 9 times with a remainder of 54.
The next digit of our result is 9. 
Result so far: 57079.0
If we subtract 1242 from 1296, we get 54.
Grab the next digit (0) from the dividend, add it to 54, then carry on: 540 / 138

Let's proceed to step 8:
138 can be fit into 540 3 times, resulting in a remainder of 126.
Write down 3 as next digit of the result. 
Result so far: 570793.0
If we take 414 away from 540, we end up with 126.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1260, and continue the process.

Moving on to step 9:
1260 divided by 138 is 9 with a remainder of 18.
Put 9 as the next digit of the answer. 
Result so far: 570793.9
Subtract 1242 from 1260 to get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

On to step 10:
138 goes into 180 1 times with a remainder of 42.
Record the quotient 1 as the next digit in the result. 
Result so far: 570793.91
Subtracting 138 from 180 leaves us with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Let's proceed to step 11:
The number 138 fits into 420 3 times, leaving a remainder of 6.
Write down 3 as next digit of the result. 
Result so far: 570793.913
If we subtract 414 from 420, 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.

Step 12:
When dividing 60 by 138, we get 0 with a remainder of 60.
The number 0 becomes the next digit in our result. 
Result so far: 570793.913
If we take 0 away from 60, we end up with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Advancing to step 13:
When dividing 600 by 138, we get 4 with a remainder of 48.
The next digit of our result is 4. 
Result so far: 570793.91304
Subtract 552 from 600 to get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Let's proceed to step 14:
If we divide 480 by 138, we get 3 and a remainder of 66.
Write down 3 as next digit of the result. 
Result so far: 570793.913043
The remainder is 66 after subtracting 414 from 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Let's proceed to step 15:
The number 138 fits into 660 4 times, leaving a remainder of 108.
Record the quotient 4 as the next digit in the result. 
Result so far: 570793.9130434
Deduct 552 from 660 and we're left with 108.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1080, and continue the process.

Step 16:
If we divide 1080 by 138, we get 7 and a remainder of 114.
Use 7 as the next digit of our solution. 
Result so far: 570793.91304347
Subtract 966 from 1080 to get 114.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1140, and continue the process.

In conclusion, the division gives 570793.91304347 with a balance of 1.14e-07.
