621811 ÷ 98 
Let's see how many times 98 fits into 621811.

Going ahead to step 1:
The number 98 fits into 6 0 times, leaving 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.
Take the next digit (2) from the dividend and append it to 6, then repeat: 62 / 98

Let's proceed to step 2:
The number 98 fits into 62 0 times, leaving a remainder of 62.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 62 and we're left with 62.
Fetch the next digit (1) from the dividend, attach it to 62 and continue: 621 / 98

Step 3:
If we divide 621 by 98, we get 6 and a remainder of 33.
Record the quotient 6 as the next digit in the result. 
Result so far: 6.0
Subtracting 588 from 621 leaves us with 33.
Append the next digit (8) from the dividend to 33 and continue with: 338 / 98

Moving on to step 4:
When dividing 338 by 98, we get 3 with a remainder of 44.
The number 3 becomes the next digit in our result. 
Result so far: 63.0
Subtracting 294 from 338 leaves us with 44.
Include the next digit (1) from the dividend after 44, then repeat: 441 / 98

Going ahead to step 5:
If we divide 441 by 98, we get 4 and a remainder of 49.
Record the quotient 4 as the next digit in the result. 
Result so far: 634.0
Subtracting 392 from 441 leaves us with 49.
Fetch the next digit (1) from the dividend, attach it to 49 and continue: 491 / 98

Going ahead to step 6:
When dividing 491 by 98, we get 5 with a remainder of 1.
The next digit of our result is 5. 
Result so far: 6345.0
Deduct 490 from 491 and we're left with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

On to step 7:
98 can be fit into 10 0 times, resulting in a remainder of 10.
Use 0 as the next digit of our solution. 
Result so far: 6345.0
Subtract 0 from 10 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 8:
If we divide 100 by 98, we get 1 and a remainder of 2.
The number 1 becomes the next digit in our result. 
Result so far: 6345.01
If we subtract 98 from 100, we get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Moving on to step 9:
98 goes into 20 0 times with a remainder of 20.
Record the quotient 0 as the next digit in the result. 
Result so far: 6345.01
Subtract 0 from 20 to 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.

Going ahead to step 10:
98 goes into 200 2 times with a remainder of 4.
The number 2 becomes the next digit in our result. 
Result so far: 6345.0102
The remainder is 4 after subtracting 196 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Advancing to step 11:
40 divided by 98 is 0 with a remainder of 40.
Put 0 as the next digit of the answer. 
Result so far: 6345.0102
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.

Moving on to step 12:
The number 98 fits into 400 4 times, leaving a remainder of 8.
The number 4 becomes the next digit in our result. 
Result so far: 6345.010204
Subtracting 392 from 400 leaves us with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Step 13:
When dividing 80 by 98, we get 0 with a remainder of 80.
Record the quotient 0 as the next digit in the result. 
Result so far: 6345.010204
Subtract 0 from 80 to 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.

Moving on to step 14:
98 goes into 800 8 times with a remainder of 16.
Put 8 as the next digit of the answer. 
Result so far: 6345.01020408
The remainder is 16 after subtracting 784 from 800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

After the division, we end up with 6345.01020408 and a remainder of 1.6e-08.
