620643 ÷ 98 
We're looking to find how many times 98 goes into 620643.

Let's proceed to step 1:
When dividing 6 by 98, we get 0 with a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Fetch the next digit (2) from the dividend, attach it to 6 and continue: 62 / 98

Let's proceed to step 2:
When dividing 62 by 98, we get 0 with a remainder of 62.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 62 and we're left with 62.
Append the next digit (0) from the dividend to 62 and continue with: 620 / 98

Advancing to step 3:
The number 98 fits into 620 6 times, leaving a remainder of 32.
Use 6 as the next digit of our solution. 
Result so far: 6.0
Subtract 588 from 620 to get 32.
Fetch the next digit (6) from the dividend, attach it to 32 and continue: 326 / 98

Moving on to step 4:
If we divide 326 by 98, we get 3 and a remainder of 32.
Write down 3 as next digit of the result. 
Result so far: 63.0
Deduct 294 from 326 and we're left with 32.
Take the next digit (4) from the dividend and append it to 32, then repeat: 324 / 98

On to step 5:
324 divided by 98 is 3 with a remainder of 30.
The number 3 becomes the next digit in our result. 
Result so far: 633.0
Subtract 294 from 324 to get 30.
Bring next digit (3) of the dividend behind the 30 and repeat the process: 303 / 98

Moving on to step 6:
If we divide 303 by 98, we get 3 and a remainder of 9.
The next digit of our result is 3. 
Result so far: 6333.0
If we take 294 away from 303, we end up with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Let's proceed to step 7:
If we divide 90 by 98, we get 0 and a remainder of 90.
The number 0 becomes the next digit in our result. 
Result so far: 6333.0
The remainder is 90 after subtracting 0 from 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

Going ahead to step 8:
98 goes into 900 9 times with a remainder of 18.
Record the quotient 9 as the next digit in the result. 
Result so far: 6333.09
Subtracting 882 from 900 leaves us with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Let's proceed to step 9:
98 goes into 180 1 times with a remainder of 82.
Write down 1 as next digit of the result. 
Result so far: 6333.091
Subtract 98 from 180 to get 82.
Since there are no more digits in the dividend, we add a zero to the remainder making it 820, and continue the process.

Let's proceed to step 10:
When dividing 820 by 98, we get 8 with a remainder of 36.
Use 8 as the next digit of our solution. 
Result so far: 6333.0918
The remainder is 36 after subtracting 784 from 820.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Advancing to step 11:
If we divide 360 by 98, we get 3 and a remainder of 66.
Record the quotient 3 as the next digit in the result. 
Result so far: 6333.09183
Subtract 294 from 360 to get 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Let's proceed to step 12:
The number 98 fits into 660 6 times, leaving a remainder of 72.
Put 6 as the next digit of the answer. 
Result so far: 6333.091836
Deduct 588 from 660 and we're left 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.

Let's proceed to step 13:
If we divide 720 by 98, we get 7 and a remainder of 34.
The number 7 becomes the next digit in our result. 
Result so far: 6333.0918367
Subtracting 686 from 720 leaves us 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.

Going ahead to step 14:
98 goes into 340 3 times with a remainder of 46.
Use 3 as the next digit of our solution. 
Result so far: 6333.09183673
Deduct 294 from 340 and we're left with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Our division results in 6333.09183673 with a remaining 4.6e-08.
