We divide 640140 by 98
We're looking to find how many times 98 goes into 640140.

Advancing to step 1:
When dividing 6 by 98, we get 0 with a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Include the next digit (4) from the dividend after 6, then repeat: 64 / 98

Advancing to step 2:
The number 98 fits into 64 0 times, leaving a remainder of 64.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 64 leaves us with 64.
Take the next digit (0) from the dividend and append it to 64, then repeat: 640 / 98

On to step 3:
When dividing 640 by 98, we get 6 with a remainder of 52.
The next digit of our result is 6. 
Result so far: 6.0
Deduct 588 from 640 and we're left with 52.
Bring next digit (1) of the dividend behind the 52 and repeat the process: 521 / 98

On to step 4:
If we divide 521 by 98, we get 5 and a remainder of 31.
Use 5 as the next digit of our solution. 
Result so far: 65.0
Subtracting 490 from 521 leaves us with 31.
Include the next digit (4) from the dividend after 31, then repeat: 314 / 98

Let's proceed to step 5:
98 can be fit into 314 3 times, resulting in a remainder of 20.
Write down 3 as next digit of the result. 
Result so far: 653.0
The remainder is 20 after subtracting 294 from 314.
Bring next digit (0) of the dividend behind the 20 and repeat the process: 200 / 98

Step 6:
When dividing 200 by 98, we get 2 with a remainder of 4.
Write down 2 as next digit of the result. 
Result so far: 6532.0
Subtract 196 from 200 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Going ahead to step 7:
If we divide 40 by 98, we get 0 and a remainder of 40.
Write down 0 as next digit of the result. 
Result so far: 6532.0
If we subtract 0 from 40, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Advancing to step 8:
If we divide 400 by 98, we get 4 and a remainder of 8.
Use 4 as the next digit of our solution. 
Result so far: 6532.04
The remainder is 8 after subtracting 392 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Step 9:
98 can be fit into 80 0 times, resulting in a remainder of 80.
The next digit of our result is 0. 
Result so far: 6532.04
If we subtract 0 from 80, we get 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

On to step 10:
98 can be fit into 800 8 times, resulting in a remainder of 16.
The number 8 becomes the next digit in our result. 
Result so far: 6532.0408
Subtracting 784 from 800 leaves us with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Advancing to step 11:
98 goes into 160 1 times with a remainder of 62.
The next digit of our result is 1. 
Result so far: 6532.04081
If we subtract 98 from 160, we get 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Advancing to step 12:
The number 98 fits into 620 6 times, leaving a remainder of 32.
The next digit of our result is 6. 
Result so far: 6532.040816
If we take 588 away from 620, we end up with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Moving on to step 13:
320 divided by 98 is 3 with a remainder of 26.
Record the quotient 3 as the next digit in the result. 
Result so far: 6532.0408163
If we take 294 away from 320, we end up with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Moving on to step 14:
When dividing 260 by 98, we get 2 with a remainder of 64.
Put 2 as the next digit of the answer. 
Result so far: 6532.04081632
Subtracting 196 from 260 leaves us with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

After the division, we end up with 6532.04081632 and a remainder of 6.4e-08.
