Let's divide 31136977 by 80
We want to figure out the number of times 31136977 can be divided by 80.

Step 1:
When dividing 3 by 80, we get 0 with a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Take the next digit (1) from the dividend and append it to 3, then repeat: 31 / 80

Advancing to step 2:
80 goes into 31 0 times with a remainder of 31.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 31 to get 31.
Fetch the next digit (1) from the dividend, attach it to 31 and continue: 311 / 80

On to step 3:
80 can be fit into 311 3 times, resulting in a remainder of 71.
Write down 3 as next digit of the result. 
Result so far: 3.0
Subtracting 240 from 311 leaves us with 71.
Append the next digit (3) from the dividend to 71 and continue with: 713 / 80

Going ahead to step 4:
When dividing 713 by 80, we get 8 with a remainder of 73.
Write down 8 as next digit of the result. 
Result so far: 38.0
If we subtract 640 from 713, we get 73.
Grab the next digit (6) from the dividend, add it to 73, then carry on: 736 / 80

Let's proceed to step 5:
80 can be fit into 736 9 times, resulting in a remainder of 16.
Use 9 as the next digit of our solution. 
Result so far: 389.0
If we subtract 720 from 736, we get 16.
Append the next digit (9) from the dividend to 16 and continue with: 169 / 80

Advancing to step 6:
169 divided by 80 is 2 with a remainder of 9.
Put 2 as the next digit of the answer. 
Result so far: 3892.0
If we subtract 160 from 169, we get 9.
Include the next digit (7) from the dividend after 9, then repeat: 97 / 80

Let's proceed to step 7:
80 goes into 97 1 times with a remainder of 17.
Record the quotient 1 as the next digit in the result. 
Result so far: 38921.0
Deduct 80 from 97 and we're left with 17.
Take the next digit (7) from the dividend and append it to 17, then repeat: 177 / 80

Moving on to step 8:
80 can be fit into 177 2 times, resulting in a remainder of 17.
The next digit of our result is 2. 
Result so far: 389212.0
If we subtract 160 from 177, we get 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Moving on to step 9:
80 goes into 170 2 times with a remainder of 10.
The number 2 becomes the next digit in our result. 
Result so far: 389212.2
Subtract 160 from 170 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 10:
If we divide 100 by 80, we get 1 and a remainder of 20.
Put 1 as the next digit of the answer. 
Result so far: 389212.21
If we subtract 80 from 100, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Let's proceed to step 11:
80 goes into 200 2 times with a remainder of 40.
Write down 2 as next digit of the result. 
Result so far: 389212.212
Deduct 160 from 200 and we're left with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

On to step 12:
When dividing 400 by 80, we get 5 with a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 389212.2125
Subtract 400 from 400 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.

On to step 13:
80 goes into 0 0 times with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 389212.2125
If we take 0 away from 0, 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.

Step 14:
If we divide 0 by 80, we get 0 and a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 389212.2125
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

In conclusion, the division gives 389212.2125 with a balance of 0.0.
