Let's divide 644353 by 98
Our goal is to divide 644353 by 98.

Advancing to step 1:
If we divide 6 by 98, we get 0 and a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Include the next digit (4) from the dividend after 6, then repeat: 64 / 98

Moving on to step 2:
98 goes into 64 0 times with a remainder of 64.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 64 to get 64.
Fetch the next digit (4) from the dividend, attach it to 64 and continue: 644 / 98

Step 3:
If we divide 644 by 98, we get 6 and a remainder of 56.
Put 6 as the next digit of the answer. 
Result so far: 6.0
Subtracting 588 from 644 leaves us with 56.
Fetch the next digit (3) from the dividend, attach it to 56 and continue: 563 / 98

Moving on to step 4:
98 can be fit into 563 5 times, resulting in a remainder of 73.
Write down 5 as next digit of the result. 
Result so far: 65.0
If we take 490 away from 563, we end up with 73.
Fetch the next digit (5) from the dividend, attach it to 73 and continue: 735 / 98

Let's proceed to step 5:
If we divide 735 by 98, we get 7 and a remainder of 49.
Use 7 as the next digit of our solution. 
Result so far: 657.0
Deduct 686 from 735 and we're left with 49.
Append the next digit (3) from the dividend to 49 and continue with: 493 / 98

Let's proceed to step 6:
98 can be fit into 493 5 times, resulting in a remainder of 3.
The number 5 becomes the next digit in our result. 
Result so far: 6575.0
Subtract 490 from 493 to get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

On to step 7:
98 can be fit into 30 0 times, resulting in a remainder of 30.
The next digit of our result is 0. 
Result so far: 6575.0
Subtracting 0 from 30 leaves us with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Moving on to step 8:
The number 98 fits into 300 3 times, leaving a remainder of 6.
The number 3 becomes the next digit in our result. 
Result so far: 6575.03
Subtracting 294 from 300 leaves us with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Advancing to step 9:
When dividing 60 by 98, we get 0 with a remainder of 60.
Use 0 as the next digit of our solution. 
Result so far: 6575.03
If we subtract 0 from 60, we get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Step 10:
98 can be fit into 600 6 times, resulting in a remainder of 12.
Use 6 as the next digit of our solution. 
Result so far: 6575.0306
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.

Advancing to step 11:
98 goes into 120 1 times with a remainder of 22.
Put 1 as the next digit of the answer. 
Result so far: 6575.03061
If we take 98 away from 120, we end up with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Going ahead to step 12:
98 goes into 220 2 times with a remainder of 24.
Use 2 as the next digit of our solution. 
Result so far: 6575.030612
The remainder is 24 after subtracting 196 from 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

On to step 13:
98 can be fit into 240 2 times, resulting in a remainder of 44.
The next digit of our result is 2. 
Result so far: 6575.0306122
Subtract 196 from 240 to get 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Our division results in 6575.0306122 with a remaining 4.4e-07.
