Let's divide 74279993 by 686
We want to divide 74279993 by 686.

Let's proceed to step 1:
If we divide 7 by 686, we get 0 and a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Fetch the next digit (4) from the dividend, attach it to 7 and continue: 74 / 686

Advancing to step 2:
The number 686 fits into 74 0 times, leaving a remainder of 74.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 74, we end up with 74.
Bring next digit (2) of the dividend behind the 74 and repeat the process: 742 / 686

Going ahead to step 3:
The number 686 fits into 742 1 times, leaving a remainder of 56.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Deduct 686 from 742 and we're left with 56.
Bring next digit (7) of the dividend behind the 56 and repeat the process: 567 / 686

Step 4:
The number 686 fits into 567 0 times, leaving a remainder of 567.
The next digit of our result is 0. 
Result so far: 10.0
Subtract 0 from 567 to get 567.
Take the next digit (9) from the dividend and append it to 567, then repeat: 5679 / 686

On to step 5:
The number 686 fits into 5679 8 times, leaving a remainder of 191.
Use 8 as the next digit of our solution. 
Result so far: 108.0
The remainder is 191 after subtracting 5488 from 5679.
Append the next digit (9) from the dividend to 191 and continue with: 1919 / 686

Advancing to step 6:
686 goes into 1919 2 times with a remainder of 547.
The number 2 becomes the next digit in our result. 
Result so far: 1082.0
Subtract 1372 from 1919 to get 547.
Take the next digit (9) from the dividend and append it to 547, then repeat: 5479 / 686

Advancing to step 7:
686 can be fit into 5479 7 times, resulting in a remainder of 677.
The next digit of our result is 7. 
Result so far: 10827.0
Subtracting 4802 from 5479 leaves us with 677.
Grab the next digit (3) from the dividend, add it to 677, then carry on: 6773 / 686

Let's proceed to step 8:
686 can be fit into 6773 9 times, resulting in a remainder of 599.
Record the quotient 9 as the next digit in the result. 
Result so far: 108279.0
If we take 6174 away from 6773, we end up with 599.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5990, and continue the process.

Going ahead to step 9:
The number 686 fits into 5990 8 times, leaving a remainder of 502.
The number 8 becomes the next digit in our result. 
Result so far: 108279.8
If we subtract 5488 from 5990, we get 502.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5020, and continue the process.

Going ahead to step 10:
686 goes into 5020 7 times with a remainder of 218.
Write down 7 as next digit of the result. 
Result so far: 108279.87
Subtract 4802 from 5020 to get 218.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2180, and continue the process.

Step 11:
If we divide 2180 by 686, we get 3 and a remainder of 122.
Write down 3 as next digit of the result. 
Result so far: 108279.873
Deduct 2058 from 2180 and we're left with 122.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1220, and continue the process.

Moving on to step 12:
If we divide 1220 by 686, we get 1 and a remainder of 534.
The number 1 becomes the next digit in our result. 
Result so far: 108279.8731
If we subtract 686 from 1220, we get 534.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5340, and continue the process.

Moving on to step 13:
If we divide 5340 by 686, we get 7 and a remainder of 538.
Write down 7 as next digit of the result. 
Result so far: 108279.87317
Subtract 4802 from 5340 to get 538.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5380, and continue the process.

Going ahead to step 14:
The number 686 fits into 5380 7 times, leaving a remainder of 578.
Use 7 as the next digit of our solution. 
Result so far: 108279.873177
If we take 4802 away from 5380, we end up with 578.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5780, and continue the process.

In conclusion, the division gives 108279.873177 with a balance of 5.78e-05.
