We look at the division of 428403 by 98 
Our goal is to divide 428403 by 98.

Advancing to step 1:
98 goes into 4 0 times with a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Fetch the next digit (2) from the dividend, attach it to 4 and continue: 42 / 98

Advancing to step 2:
98 can be fit into 42 0 times, resulting in a remainder of 42.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 42 after subtracting 0 from 42.
Take the next digit (8) from the dividend and append it to 42, then repeat: 428 / 98

Step 3:
The number 98 fits into 428 4 times, leaving a remainder of 36.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
Subtract 392 from 428 to get 36.
Grab the next digit (4) from the dividend, add it to 36, then carry on: 364 / 98

Moving on to step 4:
98 goes into 364 3 times with a remainder of 70.
The next digit of our result is 3. 
Result so far: 43.0
Deduct 294 from 364 and we're left with 70.
Take the next digit (0) from the dividend and append it to 70, then repeat: 700 / 98

Moving on to step 5:
700 divided by 98 is 7 with a remainder of 14.
Write down 7 as next digit of the result. 
Result so far: 437.0
Deduct 686 from 700 and we're left with 14.
Take the next digit (3) from the dividend and append it to 14, then repeat: 143 / 98

Going ahead to step 6:
143 divided by 98 is 1 with a remainder of 45.
Use 1 as the next digit of our solution. 
Result so far: 4371.0
If we take 98 away from 143, we end up with 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

On to step 7:
98 can be fit into 450 4 times, resulting in a remainder of 58.
The number 4 becomes the next digit in our result. 
Result so far: 4371.4
The remainder is 58 after subtracting 392 from 450.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Advancing to step 8:
When dividing 580 by 98, we get 5 with a remainder of 90.
Write down 5 as next digit of the result. 
Result so far: 4371.45
If we take 490 away from 580, we end up with 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

Step 9:
The number 98 fits into 900 9 times, leaving a remainder of 18.
The number 9 becomes the next digit in our result. 
Result so far: 4371.459
If we take 882 away from 900, we end up 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.

Step 10:
The number 98 fits into 180 1 times, leaving a remainder of 82.
Record the quotient 1 as the next digit in the result. 
Result so far: 4371.4591
Deduct 98 from 180 and we're left with 82.
Since there are no more digits in the dividend, we add a zero to the remainder making it 820, and continue the process.

Advancing to step 11:
820 divided by 98 is 8 with a remainder of 36.
Use 8 as the next digit of our solution. 
Result so far: 4371.45918
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.

On to step 12:
The number 98 fits into 360 3 times, leaving a remainder of 66.
Use 3 as the next digit of our solution. 
Result so far: 4371.459183
Deduct 294 from 360 and we're left with 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

On to step 13:
98 can be fit into 660 6 times, resulting in a remainder of 72.
The number 6 becomes the next digit in our result. 
Result so far: 4371.4591836
If we subtract 588 from 660, we get 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Step 14:
720 divided by 98 is 7 with a remainder of 34.
The next digit of our result is 7. 
Result so far: 4371.45918367
If we subtract 686 from 720, we get 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

After the division, we end up with 4371.45918367 and a remainder of 3.4e-08.
