80289617 divided by 807 
We want to divide 80289617 by 807.

On to step 1:
The number 807 fits into 8 0 times, leaving a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Grab the next digit (0) from the dividend, add it to 8, then carry on: 80 / 807

Moving on to step 2:
The number 807 fits into 80 0 times, leaving a remainder of 80.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 80, we end up with 80.
Fetch the next digit (2) from the dividend, attach it to 80 and continue: 802 / 807

Moving on to step 3:
807 can be fit into 802 0 times, resulting in a remainder of 802.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 802 leaves us with 802.
Fetch the next digit (8) from the dividend, attach it to 802 and continue: 8028 / 807

Going ahead to step 4:
The number 807 fits into 8028 9 times, leaving a remainder of 765.
Write down 9 as next digit of the result. 
Result so far: 9.0
Deduct 7263 from 8028 and we're left with 765.
Fetch the next digit (9) from the dividend, attach it to 765 and continue: 7659 / 807

On to step 5:
807 can be fit into 7659 9 times, resulting in a remainder of 396.
The number 9 becomes the next digit in our result. 
Result so far: 99.0
If we subtract 7263 from 7659, we get 396.
Grab the next digit (6) from the dividend, add it to 396, then carry on: 3966 / 807

Advancing to step 6:
807 can be fit into 3966 4 times, resulting in a remainder of 738.
The next digit of our result is 4. 
Result so far: 994.0
Subtracting 3228 from 3966 leaves us with 738.
Append the next digit (1) from the dividend to 738 and continue with: 7381 / 807

On to step 7:
807 goes into 7381 9 times with a remainder of 118.
Put 9 as the next digit of the answer. 
Result so far: 9949.0
Subtracting 7263 from 7381 leaves us with 118.
Grab the next digit (7) from the dividend, add it to 118, then carry on: 1187 / 807

On to step 8:
The number 807 fits into 1187 1 times, leaving a remainder of 380.
The number 1 becomes the next digit in our result. 
Result so far: 99491.0
Deduct 807 from 1187 and we're left with 380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3800, and continue the process.

Step 9:
The number 807 fits into 3800 4 times, leaving a remainder of 572.
Record the quotient 4 as the next digit in the result. 
Result so far: 99491.4
Subtract 3228 from 3800 to get 572.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5720, and continue the process.

Advancing to step 10:
When dividing 5720 by 807, we get 7 with a remainder of 71.
The next digit of our result is 7. 
Result so far: 99491.47
If we subtract 5649 from 5720, we get 71.
Since there are no more digits in the dividend, we add a zero to the remainder making it 710, and continue the process.

Let's proceed to step 11:
710 divided by 807 is 0 with a remainder of 710.
The next digit of our result is 0. 
Result so far: 99491.47
Deduct 0 from 710 and we're left with 710.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7100, and continue the process.

Moving on to step 12:
807 can be fit into 7100 8 times, resulting in a remainder of 644.
Put 8 as the next digit of the answer. 
Result so far: 99491.4708
The remainder is 644 after subtracting 6456 from 7100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6440, and continue the process.

Step 13:
When dividing 6440 by 807, we get 7 with a remainder of 791.
Use 7 as the next digit of our solution. 
Result so far: 99491.47087
If we subtract 5649 from 6440, we get 791.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7910, and continue the process.

Advancing to step 14:
The number 807 fits into 7910 9 times, leaving a remainder of 647.
Put 9 as the next digit of the answer. 
Result so far: 99491.470879
If we take 7263 away from 7910, we end up with 647.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6470, and continue the process.

Advancing to step 15:
6470 divided by 807 is 8 with a remainder of 14.
The next digit of our result is 8. 
Result so far: 99491.4708798
If we subtract 6456 from 6470, we get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Advancing to step 16:
807 goes into 140 0 times with a remainder of 140.
The next digit of our result is 0. 
Result so far: 99491.4708798
If we subtract 0 from 140, we get 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

In conclusion, the division gives 99491.4708798 with a balance of 1.4e-07.
