80579673 ÷ 68 
We want to divide 80579673 by 68.

Going ahead to step 1:
The number 68 fits into 8 0 times, leaving a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Grab the next digit (0) from the dividend, add it to 8, then carry on: 80 / 68

On to step 2:
68 goes into 80 1 times with a remainder of 12.
Write down 1 as next digit of the result. 
Result so far: 1.0
Deduct 68 from 80 and we're left with 12.
Append the next digit (5) from the dividend to 12 and continue with: 125 / 68

On to step 3:
If we divide 125 by 68, we get 1 and a remainder of 57.
Record the quotient 1 as the next digit in the result. 
Result so far: 11.0
Deduct 68 from 125 and we're left with 57.
Grab the next digit (7) from the dividend, add it to 57, then carry on: 577 / 68

Going ahead to step 4:
The number 68 fits into 577 8 times, leaving a remainder of 33.
Put 8 as the next digit of the answer. 
Result so far: 118.0
Subtracting 544 from 577 leaves us with 33.
Grab the next digit (9) from the dividend, add it to 33, then carry on: 339 / 68

On to step 5:
68 can be fit into 339 4 times, resulting in a remainder of 67.
Record the quotient 4 as the next digit in the result. 
Result so far: 1184.0
Subtract 272 from 339 to get 67.
Take the next digit (6) from the dividend and append it to 67, then repeat: 676 / 68

On to step 6:
The number 68 fits into 676 9 times, leaving a remainder of 64.
Use 9 as the next digit of our solution. 
Result so far: 11849.0
Subtract 612 from 676 to get 64.
Take the next digit (7) from the dividend and append it to 64, then repeat: 647 / 68

Step 7:
If we divide 647 by 68, we get 9 and a remainder of 35.
Put 9 as the next digit of the answer. 
Result so far: 118499.0
If we subtract 612 from 647, we get 35.
Grab the next digit (3) from the dividend, add it to 35, then carry on: 353 / 68

On to step 8:
The number 68 fits into 353 5 times, leaving a remainder of 13.
Put 5 as the next digit of the answer. 
Result so far: 1184995.0
Subtract 340 from 353 to get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Moving on to step 9:
130 divided by 68 is 1 with a remainder of 62.
Write down 1 as next digit of the result. 
Result so far: 1184995.1
Subtracting 68 from 130 leaves us with 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Let's proceed to step 10:
The number 68 fits into 620 9 times, leaving a remainder of 8.
Put 9 as the next digit of the answer. 
Result so far: 1184995.19
If we take 612 away from 620, we end up with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Advancing to step 11:
When dividing 80 by 68, we get 1 with a remainder of 12.
The next digit of our result is 1. 
Result so far: 1184995.191
The remainder is 12 after subtracting 68 from 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Advancing to step 12:
If we divide 120 by 68, we get 1 and a remainder of 52.
Use 1 as the next digit of our solution. 
Result so far: 1184995.1911
If we subtract 68 from 120, we get 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

The final result is 1184995.1911 with a remainder of 0.00052.
