We're dividing 98422403 by 686 
We want to divide 98422403 by 686.

Moving on to step 1:
9 divided by 686 is 0 with a remainder of 9.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 9 leaves us with 9.
Fetch the next digit (8) from the dividend, attach it to 9 and continue: 98 / 686

Advancing to step 2:
98 divided by 686 is 0 with a remainder of 98.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 98, we get 98.
Include the next digit (4) from the dividend after 98, then repeat: 984 / 686

On to step 3:
686 goes into 984 1 times with a remainder of 298.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
The remainder is 298 after subtracting 686 from 984.
Include the next digit (2) from the dividend after 298, then repeat: 2982 / 686

Going ahead to step 4:
If we divide 2982 by 686, we get 4 and a remainder of 238.
Use 4 as the next digit of our solution. 
Result so far: 14.0
The remainder is 238 after subtracting 2744 from 2982.
Append the next digit (2) from the dividend to 238 and continue with: 2382 / 686

Going ahead to step 5:
The number 686 fits into 2382 3 times, leaving a remainder of 324.
Record the quotient 3 as the next digit in the result. 
Result so far: 143.0
Subtract 2058 from 2382 to get 324.
Grab the next digit (4) from the dividend, add it to 324, then carry on: 3244 / 686

On to step 6:
3244 divided by 686 is 4 with a remainder of 500.
Put 4 as the next digit of the answer. 
Result so far: 1434.0
If we subtract 2744 from 3244, we get 500.
Include the next digit (0) from the dividend after 500, then repeat: 5000 / 686

Let's proceed to step 7:
The number 686 fits into 5000 7 times, leaving a remainder of 198.
The number 7 becomes the next digit in our result. 
Result so far: 14347.0
The remainder is 198 after subtracting 4802 from 5000.
Include the next digit (3) from the dividend after 198, then repeat: 1983 / 686

Step 8:
686 goes into 1983 2 times with a remainder of 611.
The number 2 becomes the next digit in our result. 
Result so far: 143472.0
Deduct 1372 from 1983 and we're left with 611.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6110, and continue the process.

Advancing to step 9:
686 goes into 6110 8 times with a remainder of 622.
Write down 8 as next digit of the result. 
Result so far: 143472.8
Subtract 5488 from 6110 to get 622.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6220, and continue the process.

On to step 10:
686 goes into 6220 9 times with a remainder of 46.
Write down 9 as next digit of the result. 
Result so far: 143472.89
The remainder is 46 after subtracting 6174 from 6220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Let's proceed to step 11:
460 divided by 686 is 0 with a remainder of 460.
Record the quotient 0 as the next digit in the result. 
Result so far: 143472.89
If we take 0 away from 460, we end up with 460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4600, and continue the process.

Step 12:
686 can be fit into 4600 6 times, resulting in a remainder of 484.
The number 6 becomes the next digit in our result. 
Result so far: 143472.8906
Subtracting 4116 from 4600 leaves us with 484.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4840, and continue the process.

On to step 13:
If we divide 4840 by 686, we get 7 and a remainder of 38.
Use 7 as the next digit of our solution. 
Result so far: 143472.89067
Subtracting 4802 from 4840 leaves us with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Moving on to step 14:
The number 686 fits into 380 0 times, leaving a remainder of 380.
Record the quotient 0 as the next digit in the result. 
Result so far: 143472.89067
Subtracting 0 from 380 leaves us with 380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3800, and continue the process.

Let's proceed to step 15:
686 goes into 3800 5 times with a remainder of 370.
Write down 5 as next digit of the result. 
Result so far: 143472.8906705
If we subtract 3430 from 3800, we get 370.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3700, and continue the process.

Moving on to step 16:
686 can be fit into 3700 5 times, resulting in a remainder of 270.
Use 5 as the next digit of our solution. 
Result so far: 143472.89067055
Subtract 3430 from 3700 to get 270.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2700, and continue the process.

The final result is 143472.89067055 with a remainder of 2.7e-07.
