We divide 34488073 by 80
Our goal is to divide 34488073 by 80.

On to step 1:
80 goes into 3 0 times with a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Include the next digit (4) from the dividend after 3, then repeat: 34 / 80

On to step 2:
When dividing 34 by 80, we get 0 with a remainder of 34.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 34 after subtracting 0 from 34.
Append the next digit (4) from the dividend to 34 and continue with: 344 / 80

Step 3:
344 divided by 80 is 4 with a remainder of 24.
Put 4 as the next digit of the answer. 
Result so far: 4.0
If we take 320 away from 344, we end up with 24.
Append the next digit (8) from the dividend to 24 and continue with: 248 / 80

Step 4:
80 can be fit into 248 3 times, resulting in a remainder of 8.
The next digit of our result is 3. 
Result so far: 43.0
If we subtract 240 from 248, we get 8.
Take the next digit (8) from the dividend and append it to 8, then repeat: 88 / 80

Going ahead to step 5:
80 goes into 88 1 times with a remainder of 8.
Record the quotient 1 as the next digit in the result. 
Result so far: 431.0
Deduct 80 from 88 and we're left with 8.
Append the next digit (0) from the dividend to 8 and continue with: 80 / 80

Going ahead to step 6:
When dividing 80 by 80, we get 1 with a remainder of 0.
Use 1 as the next digit of our solution. 
Result so far: 4311.0
Subtract 80 from 80 to get 0.
Grab the next digit (7) from the dividend, add it to 0, then carry on: 7 / 80

Going ahead to step 7:
80 goes into 7 0 times with a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 43110.0
Subtracting 0 from 7 leaves us with 7.
Include the next digit (3) from the dividend after 7, then repeat: 73 / 80

On to step 8:
80 can be fit into 73 0 times, resulting in a remainder of 73.
Record the quotient 0 as the next digit in the result. 
Result so far: 431100.0
If we take 0 away from 73, we end up with 73.
Since there are no more digits in the dividend, we add a zero to the remainder making it 730, and continue the process.

Moving on to step 9:
The number 80 fits into 730 9 times, leaving a remainder of 10.
Use 9 as the next digit of our solution. 
Result so far: 431100.9
Subtracting 720 from 730 leaves us 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.

Step 10:
When dividing 100 by 80, we get 1 with a remainder of 20.
Put 1 as the next digit of the answer. 
Result so far: 431100.91
The remainder is 20 after subtracting 80 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

On to step 11:
80 can be fit into 200 2 times, resulting in a remainder of 40.
The number 2 becomes the next digit in our result. 
Result so far: 431100.912
If we subtract 160 from 200, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Advancing to step 12:
The number 80 fits into 400 5 times, leaving a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 431100.9125
Deduct 400 from 400 and we're left 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.

Going ahead to step 13:
The number 80 fits into 0 0 times, leaving a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 431100.9125
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.

Going ahead to step 14:
80 goes into 0 0 times with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 431100.9125
Subtract 0 from 0 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.

The final result is 431100.9125 with a remainder of 0.0.
