We're dividing 640123 by 98 
We're looking to find how many times 98 goes into 640123.

Moving on to step 1:
6 divided by 98 is 0 with a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Include the next digit (4) from the dividend after 6, then repeat: 64 / 98

On to step 2:
64 divided by 98 is 0 with a remainder of 64.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 64, we end up with 64.
Include the next digit (0) from the dividend after 64, then repeat: 640 / 98

Advancing to step 3:
640 divided by 98 is 6 with a remainder of 52.
The number 6 becomes the next digit in our result. 
Result so far: 6.0
Subtract 588 from 640 to get 52.
Grab the next digit (1) from the dividend, add it to 52, then carry on: 521 / 98

On to step 4:
The number 98 fits into 521 5 times, leaving a remainder of 31.
Use 5 as the next digit of our solution. 
Result so far: 65.0
If we take 490 away from 521, we end up with 31.
Take the next digit (2) from the dividend and append it to 31, then repeat: 312 / 98

Let's proceed to step 5:
The number 98 fits into 312 3 times, leaving a remainder of 18.
Write down 3 as next digit of the result. 
Result so far: 653.0
Subtract 294 from 312 to get 18.
Include the next digit (3) from the dividend after 18, then repeat: 183 / 98

Moving on to step 6:
98 can be fit into 183 1 times, resulting in a remainder of 85.
Put 1 as the next digit of the answer. 
Result so far: 6531.0
Subtracting 98 from 183 leaves us with 85.
Since there are no more digits in the dividend, we add a zero to the remainder making it 850, and continue the process.

Step 7:
98 can be fit into 850 8 times, resulting in a remainder of 66.
Write down 8 as next digit of the result. 
Result so far: 6531.8
Subtracting 784 from 850 leaves us with 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

On to step 8:
660 divided by 98 is 6 with a remainder of 72.
Record the quotient 6 as the next digit in the result. 
Result so far: 6531.86
Subtracting 588 from 660 leaves us with 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Going ahead to step 9:
When dividing 720 by 98, we get 7 with a remainder of 34.
The next digit of our result is 7. 
Result so far: 6531.867
Deduct 686 from 720 and we're left with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Moving on to step 10:
340 divided by 98 is 3 with a remainder of 46.
Record the quotient 3 as the next digit in the result. 
Result so far: 6531.8673
If we subtract 294 from 340, we get 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

On to step 11:
98 can be fit into 460 4 times, resulting in a remainder of 68.
The next digit of our result is 4. 
Result so far: 6531.86734
Deduct 392 from 460 and we're left with 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

On to step 12:
680 divided by 98 is 6 with a remainder of 92.
The next digit of our result is 6. 
Result so far: 6531.867346
The remainder is 92 after subtracting 588 from 680.
Since there are no more digits in the dividend, we add a zero to the remainder making it 920, and continue the process.

Going ahead to step 13:
If we divide 920 by 98, we get 9 and a remainder of 38.
The next digit of our result is 9. 
Result so far: 6531.8673469
Subtracting 882 from 920 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.

Advancing to step 14:
When dividing 380 by 98, we get 3 with a remainder of 86.
The next digit of our result is 3. 
Result so far: 6531.86734693
Subtract 294 from 380 to get 86.
Since there are no more digits in the dividend, we add a zero to the remainder making it 860, and continue the process.

The quotient of the division is 6531.86734693, and the remainder is 8.6e-08.
