98945073 divided by 686 
We want to divide 98945073 by 686.

On to step 1:
If we divide 9 by 686, we get 0 and a remainder of 9.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 9 and we're left with 9.
Fetch the next digit (8) from the dividend, attach it to 9 and continue: 98 / 686

Advancing to step 2:
The number 686 fits into 98 0 times, leaving a remainder of 98.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 98 and we're left with 98.
Bring next digit (9) of the dividend behind the 98 and repeat the process: 989 / 686

Advancing to step 3:
If we divide 989 by 686, we get 1 and a remainder of 303.
Use 1 as the next digit of our solution. 
Result so far: 1.0
The remainder is 303 after subtracting 686 from 989.
Fetch the next digit (4) from the dividend, attach it to 303 and continue: 3034 / 686

Let's proceed to step 4:
If we divide 3034 by 686, we get 4 and a remainder of 290.
Record the quotient 4 as the next digit in the result. 
Result so far: 14.0
Deduct 2744 from 3034 and we're left with 290.
Append the next digit (5) from the dividend to 290 and continue with: 2905 / 686

Advancing to step 5:
The number 686 fits into 2905 4 times, leaving a remainder of 161.
Use 4 as the next digit of our solution. 
Result so far: 144.0
Deduct 2744 from 2905 and we're left with 161.
Fetch the next digit (0) from the dividend, attach it to 161 and continue: 1610 / 686

On to step 6:
The number 686 fits into 1610 2 times, leaving a remainder of 238.
Use 2 as the next digit of our solution. 
Result so far: 1442.0
If we take 1372 away from 1610, we end up with 238.
Grab the next digit (7) from the dividend, add it to 238, then carry on: 2387 / 686

On to step 7:
If we divide 2387 by 686, we get 3 and a remainder of 329.
The next digit of our result is 3. 
Result so far: 14423.0
If we take 2058 away from 2387, we end up with 329.
Bring next digit (3) of the dividend behind the 329 and repeat the process: 3293 / 686

Advancing to step 8:
If we divide 3293 by 686, we get 4 and a remainder of 549.
Use 4 as the next digit of our solution. 
Result so far: 144234.0
The remainder is 549 after subtracting 2744 from 3293.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5490, and continue the process.

Advancing to step 9:
5490 divided by 686 is 8 with a remainder of 2.
Use 8 as the next digit of our solution. 
Result so far: 144234.8
Subtracting 5488 from 5490 leaves us with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Let's proceed to step 10:
The number 686 fits into 20 0 times, leaving a remainder of 20.
The number 0 becomes the next digit in our result. 
Result so far: 144234.8
If we subtract 0 from 20, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Let's proceed to step 11:
200 divided by 686 is 0 with a remainder of 200.
The number 0 becomes the next digit in our result. 
Result so far: 144234.8
If we subtract 0 from 200, we get 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

The final result is 144234.8 with a remainder of 0.02.
