We're dividing 300621 by 98 
We want to figure out the number of times 300621 can be divided by 98.

Advancing to step 1:
The number 98 fits into 3 0 times, leaving a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Fetch the next digit (0) from the dividend, attach it to 3 and continue: 30 / 98

On to step 2:
If we divide 30 by 98, we get 0 and a remainder of 30.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 30 after subtracting 0 from 30.
Grab the next digit (0) from the dividend, add it to 30, then carry on: 300 / 98

Moving on to step 3:
98 goes into 300 3 times with a remainder of 6.
Write down 3 as next digit of the result. 
Result so far: 3.0
The remainder is 6 after subtracting 294 from 300.
Append the next digit (6) from the dividend to 6 and continue with: 66 / 98

On to step 4:
98 goes into 66 0 times with a remainder of 66.
Record the quotient 0 as the next digit in the result. 
Result so far: 30.0
If we take 0 away from 66, we end up with 66.
Grab the next digit (2) from the dividend, add it to 66, then carry on: 662 / 98

On to step 5:
The number 98 fits into 662 6 times, leaving a remainder of 74.
The number 6 becomes the next digit in our result. 
Result so far: 306.0
Deduct 588 from 662 and we're left with 74.
Grab the next digit (1) from the dividend, add it to 74, then carry on: 741 / 98

Going ahead to step 6:
98 goes into 741 7 times with a remainder of 55.
Use 7 as the next digit of our solution. 
Result so far: 3067.0
If we take 686 away from 741, we end up with 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Moving on to step 7:
98 goes into 550 5 times with a remainder of 60.
Write down 5 as next digit of the result. 
Result so far: 3067.5
Subtracting 490 from 550 leaves us with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Going ahead to step 8:
The number 98 fits into 600 6 times, leaving a remainder of 12.
Write down 6 as next digit of the result. 
Result so far: 3067.56
Subtracting 588 from 600 leaves us with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Let's proceed to step 9:
98 goes into 120 1 times with a remainder of 22.
The number 1 becomes the next digit in our result. 
Result so far: 3067.561
Subtract 98 from 120 to get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Advancing to step 10:
98 can be fit into 220 2 times, resulting in a remainder of 24.
Write down 2 as next digit of the result. 
Result so far: 3067.5612
Deduct 196 from 220 and we're left with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Moving on to step 11:
When dividing 240 by 98, we get 2 with a remainder of 44.
Put 2 as the next digit of the answer. 
Result so far: 3067.56122
Deduct 196 from 240 and we're left with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

The final outcome is 3067.56122, with a leftover of 4.4e-05.
