Let's divide 80968877 by 138
We want to divide 80968877 by 138.

Advancing to step 1:
138 goes into 8 0 times with a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Append the next digit (0) from the dividend to 8 and continue with: 80 / 138

Step 2:
When dividing 80 by 138, we get 0 with a remainder of 80.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 80 and we're left with 80.
Take the next digit (9) from the dividend and append it to 80, then repeat: 809 / 138

Step 3:
809 divided by 138 is 5 with a remainder of 119.
The number 5 becomes the next digit in our result. 
Result so far: 5.0
Deduct 690 from 809 and we're left with 119.
Grab the next digit (6) from the dividend, add it to 119, then carry on: 1196 / 138

Moving on to step 4:
138 can be fit into 1196 8 times, resulting in a remainder of 92.
Use 8 as the next digit of our solution. 
Result so far: 58.0
Subtract 1104 from 1196 to get 92.
Grab the next digit (8) from the dividend, add it to 92, then carry on: 928 / 138

Moving on to step 5:
138 goes into 928 6 times with a remainder of 100.
Use 6 as the next digit of our solution. 
Result so far: 586.0
If we subtract 828 from 928, we get 100.
Include the next digit (8) from the dividend after 100, then repeat: 1008 / 138

Moving on to step 6:
138 can be fit into 1008 7 times, resulting in a remainder of 42.
Put 7 as the next digit of the answer. 
Result so far: 5867.0
Subtracting 966 from 1008 leaves us with 42.
Take the next digit (7) from the dividend and append it to 42, then repeat: 427 / 138

On to step 7:
138 goes into 427 3 times with a remainder of 13.
The number 3 becomes the next digit in our result. 
Result so far: 58673.0
Subtract 414 from 427 to get 13.
Grab the next digit (7) from the dividend, add it to 13, then carry on: 137 / 138

Step 8:
If we divide 137 by 138, we get 0 and a remainder of 137.
Use 0 as the next digit of our solution. 
Result so far: 586730.0
Deduct 0 from 137 and we're left with 137.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1370, and continue the process.

On to step 9:
138 can be fit into 1370 9 times, resulting in a remainder of 128.
Write down 9 as next digit of the result. 
Result so far: 586730.9
The remainder is 128 after subtracting 1242 from 1370.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1280, and continue the process.

On to step 10:
If we divide 1280 by 138, we get 9 and a remainder of 38.
Record the quotient 9 as the next digit in the result. 
Result so far: 586730.99
Subtracting 1242 from 1280 leaves us with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

After the division, we end up with 586730.99 and a remainder of 0.038.
