We're dividing 66979173 by 807 
We want to divide 66979173 by 807.

Advancing to step 1:
If we divide 6 by 807, we get 0 and a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Bring next digit (6) of the dividend behind the 6 and repeat the process: 66 / 807

Going ahead to step 2:
807 can be fit into 66 0 times, resulting in a remainder of 66.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 66, we end up with 66.
Grab the next digit (9) from the dividend, add it to 66, then carry on: 669 / 807

On to step 3:
The number 807 fits into 669 0 times, leaving a remainder of 669.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 669 and we're left with 669.
Append the next digit (7) from the dividend to 669 and continue with: 6697 / 807

Advancing to step 4:
If we divide 6697 by 807, we get 8 and a remainder of 241.
Write down 8 as next digit of the result. 
Result so far: 8.0
If we take 6456 away from 6697, we end up with 241.
Include the next digit (9) from the dividend after 241, then repeat: 2419 / 807

Moving on to step 5:
807 goes into 2419 2 times with a remainder of 805.
Put 2 as the next digit of the answer. 
Result so far: 82.0
Deduct 1614 from 2419 and we're left with 805.
Grab the next digit (1) from the dividend, add it to 805, then carry on: 8051 / 807

On to step 6:
807 can be fit into 8051 9 times, resulting in a remainder of 788.
The number 9 becomes the next digit in our result. 
Result so far: 829.0
The remainder is 788 after subtracting 7263 from 8051.
Fetch the next digit (7) from the dividend, attach it to 788 and continue: 7887 / 807

Going ahead to step 7:
807 can be fit into 7887 9 times, resulting in a remainder of 624.
Put 9 as the next digit of the answer. 
Result so far: 8299.0
If we take 7263 away from 7887, we end up with 624.
Bring next digit (3) of the dividend behind the 624 and repeat the process: 6243 / 807

On to step 8:
6243 divided by 807 is 7 with a remainder of 594.
Put 7 as the next digit of the answer. 
Result so far: 82997.0
Subtract 5649 from 6243 to get 594.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5940, and continue the process.

Going ahead to step 9:
807 can be fit into 5940 7 times, resulting in a remainder of 291.
Put 7 as the next digit of the answer. 
Result so far: 82997.7
Subtracting 5649 from 5940 leaves us with 291.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2910, and continue the process.

Let's proceed to step 10:
When dividing 2910 by 807, we get 3 with a remainder of 489.
Write down 3 as next digit of the result. 
Result so far: 82997.73
The remainder is 489 after subtracting 2421 from 2910.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4890, and continue the process.

On to step 11:
4890 divided by 807 is 6 with a remainder of 48.
Use 6 as the next digit of our solution. 
Result so far: 82997.736
Subtract 4842 from 4890 to get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Advancing to step 12:
807 goes into 480 0 times with a remainder of 480.
Use 0 as the next digit of our solution. 
Result so far: 82997.736
The remainder is 480 after subtracting 0 from 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4800, and continue the process.

Going ahead to step 13:
If we divide 4800 by 807, we get 5 and a remainder of 765.
The next digit of our result is 5. 
Result so far: 82997.73605
Deduct 4035 from 4800 and we're left with 765.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7650, and continue the process.

On to step 14:
807 goes into 7650 9 times with a remainder of 387.
Write down 9 as next digit of the result. 
Result so far: 82997.736059
Deduct 7263 from 7650 and we're left with 387.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3870, and continue the process.

Advancing to step 15:
If we divide 3870 by 807, we get 4 and a remainder of 642.
Put 4 as the next digit of the answer. 
Result so far: 82997.7360594
Deduct 3228 from 3870 and we're left with 642.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6420, and continue the process.

Advancing to step 16:
The number 807 fits into 6420 7 times, leaving a remainder of 771.
The next digit of our result is 7. 
Result so far: 82997.73605947
Subtracting 5649 from 6420 leaves us with 771.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7710, and continue the process.

In conclusion, the division gives 82997.73605947 with a balance of 7.71e-07.
