Let's divide 70979983 by 686
Our goal is to divide 70979983 by 686.

Moving on to step 1:
If we divide 7 by 686, we get 0 and a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Take the next digit (0) from the dividend and append it to 7, then repeat: 70 / 686

Going ahead to step 2:
70 divided by 686 is 0 with a remainder of 70.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 70 to get 70.
Append the next digit (9) from the dividend to 70 and continue with: 709 / 686

Moving on to step 3:
The number 686 fits into 709 1 times, leaving a remainder of 23.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we subtract 686 from 709, we get 23.
Append the next digit (7) from the dividend to 23 and continue with: 237 / 686

Step 4:
When dividing 237 by 686, we get 0 with a remainder of 237.
Put 0 as the next digit of the answer. 
Result so far: 10.0
Subtracting 0 from 237 leaves us with 237.
Include the next digit (9) from the dividend after 237, then repeat: 2379 / 686

Advancing to step 5:
686 goes into 2379 3 times with a remainder of 321.
Use 3 as the next digit of our solution. 
Result so far: 103.0
Subtracting 2058 from 2379 leaves us with 321.
Fetch the next digit (9) from the dividend, attach it to 321 and continue: 3219 / 686

Advancing to step 6:
686 can be fit into 3219 4 times, resulting in a remainder of 475.
The number 4 becomes the next digit in our result. 
Result so far: 1034.0
Subtracting 2744 from 3219 leaves us with 475.
Bring next digit (8) of the dividend behind the 475 and repeat the process: 4758 / 686

Moving on to step 7:
686 can be fit into 4758 6 times, resulting in a remainder of 642.
Write down 6 as next digit of the result. 
Result so far: 10346.0
Subtract 4116 from 4758 to get 642.
Grab the next digit (3) from the dividend, add it to 642, then carry on: 6423 / 686

Moving on to step 8:
If we divide 6423 by 686, we get 9 and a remainder of 249.
The next digit of our result is 9. 
Result so far: 103469.0
If we subtract 6174 from 6423, we get 249.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2490, and continue the process.

Step 9:
686 goes into 2490 3 times with a remainder of 432.
Use 3 as the next digit of our solution. 
Result so far: 103469.3
Subtracting 2058 from 2490 leaves us with 432.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4320, and continue the process.

Advancing to step 10:
The number 686 fits into 4320 6 times, leaving a remainder of 204.
Put 6 as the next digit of the answer. 
Result so far: 103469.36
The remainder is 204 after subtracting 4116 from 4320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2040, and continue the process.

Moving on to step 11:
686 goes into 2040 2 times with a remainder of 668.
Use 2 as the next digit of our solution. 
Result so far: 103469.362
Subtracting 1372 from 2040 leaves us with 668.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6680, and continue the process.

Let's proceed to step 12:
686 can be fit into 6680 9 times, resulting in a remainder of 506.
The next digit of our result is 9. 
Result so far: 103469.3629
Subtracting 6174 from 6680 leaves us with 506.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5060, and continue the process.

Advancing to step 13:
686 goes into 5060 7 times with a remainder of 258.
Write down 7 as next digit of the result. 
Result so far: 103469.36297
Subtract 4802 from 5060 to get 258.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2580, and continue the process.

On to step 14:
686 can be fit into 2580 3 times, resulting in a remainder of 522.
Record the quotient 3 as the next digit in the result. 
Result so far: 103469.362973
Subtract 2058 from 2580 to get 522.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5220, and continue the process.

Advancing to step 15:
If we divide 5220 by 686, we get 7 and a remainder of 418.
The number 7 becomes the next digit in our result. 
Result so far: 103469.3629737
The remainder is 418 after subtracting 4802 from 5220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4180, and continue the process.

Going ahead to step 16:
The number 686 fits into 4180 6 times, leaving a remainder of 64.
Put 6 as the next digit of the answer. 
Result so far: 103469.36297376
The remainder is 64 after subtracting 4116 from 4180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

In conclusion, the division gives 103469.36297376 with a balance of 6.4e-08.
