77917974 ÷ 807 
Our goal is to divide 77917974 by 807.

Advancing to step 1:
807 goes into 7 0 times with a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Take the next digit (7) from the dividend and append it to 7, then repeat: 77 / 807

Going ahead to step 2:
If we divide 77 by 807, we get 0 and a remainder of 77.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 77, we get 77.
Grab the next digit (9) from the dividend, add it to 77, then carry on: 779 / 807

Moving on to step 3:
779 divided by 807 is 0 with a remainder of 779.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 779 and we're left with 779.
Grab the next digit (1) from the dividend, add it to 779, then carry on: 7791 / 807

Moving on to step 4:
807 goes into 7791 9 times with a remainder of 528.
Use 9 as the next digit of our solution. 
Result so far: 9.0
Deduct 7263 from 7791 and we're left with 528.
Include the next digit (7) from the dividend after 528, then repeat: 5287 / 807

Moving on to step 5:
807 goes into 5287 6 times with a remainder of 445.
Put 6 as the next digit of the answer. 
Result so far: 96.0
The remainder is 445 after subtracting 4842 from 5287.
Take the next digit (9) from the dividend and append it to 445, then repeat: 4459 / 807

On to step 6:
When dividing 4459 by 807, we get 5 with a remainder of 424.
Put 5 as the next digit of the answer. 
Result so far: 965.0
The remainder is 424 after subtracting 4035 from 4459.
Grab the next digit (7) from the dividend, add it to 424, then carry on: 4247 / 807

Step 7:
If we divide 4247 by 807, we get 5 and a remainder of 212.
Use 5 as the next digit of our solution. 
Result so far: 9655.0
The remainder is 212 after subtracting 4035 from 4247.
Take the next digit (4) from the dividend and append it to 212, then repeat: 2124 / 807

Advancing to step 8:
807 can be fit into 2124 2 times, resulting in a remainder of 510.
Write down 2 as next digit of the result. 
Result so far: 96552.0
Subtract 1614 from 2124 to get 510.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5100, and continue the process.

Advancing to step 9:
807 can be fit into 5100 6 times, resulting in a remainder of 258.
Put 6 as the next digit of the answer. 
Result so far: 96552.6
If we take 4842 away from 5100, we end up with 258.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2580, and continue the process.

Moving on to step 10:
2580 divided by 807 is 3 with a remainder of 159.
The number 3 becomes the next digit in our result. 
Result so far: 96552.63
Deduct 2421 from 2580 and we're left with 159.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1590, and continue the process.

Going ahead to step 11:
1590 divided by 807 is 1 with a remainder of 783.
The next digit of our result is 1. 
Result so far: 96552.631
Subtracting 807 from 1590 leaves us with 783.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7830, and continue the process.

Going ahead to step 12:
When dividing 7830 by 807, we get 9 with a remainder of 567.
Write down 9 as next digit of the result. 
Result so far: 96552.6319
The remainder is 567 after subtracting 7263 from 7830.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5670, and continue the process.

Moving on to step 13:
If we divide 5670 by 807, we get 7 and a remainder of 21.
Put 7 as the next digit of the answer. 
Result so far: 96552.63197
The remainder is 21 after subtracting 5649 from 5670.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Moving on to step 14:
When dividing 210 by 807, we get 0 with a remainder of 210.
Write down 0 as next digit of the result. 
Result so far: 96552.63197
Subtracting 0 from 210 leaves us with 210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2100, and continue the process.

Advancing to step 15:
If we divide 2100 by 807, we get 2 and a remainder of 486.
Put 2 as the next digit of the answer. 
Result so far: 96552.6319702
If we take 1614 away from 2100, we end up with 486.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4860, and continue the process.

Let's proceed to step 16:
If we divide 4860 by 807, we get 6 and a remainder of 18.
Use 6 as the next digit of our solution. 
Result so far: 96552.63197026
Subtract 4842 from 4860 to get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

The final result is 96552.63197026 with a remainder of 1.8e-08.
