We're dividing 98657584 by 420 
Our goal is to divide 98657584 by 420.

Advancing to step 1:
If we divide 9 by 420, we get 0 and a remainder of 9.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 9 leaves us with 9.
Bring next digit (8) of the dividend behind the 9 and repeat the process: 98 / 420

Let's proceed to step 2:
The number 420 fits into 98 0 times, leaving a remainder of 98.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 98 after subtracting 0 from 98.
Include the next digit (6) from the dividend after 98, then repeat: 986 / 420

Going ahead to step 3:
The number 420 fits into 986 2 times, leaving a remainder of 146.
The next digit of our result is 2. 
Result so far: 2.0
Deduct 840 from 986 and we're left with 146.
Append the next digit (5) from the dividend to 146 and continue with: 1465 / 420

Moving on to step 4:
420 can be fit into 1465 3 times, resulting in a remainder of 205.
Use 3 as the next digit of our solution. 
Result so far: 23.0
Subtract 1260 from 1465 to get 205.
Include the next digit (7) from the dividend after 205, then repeat: 2057 / 420

Step 5:
The number 420 fits into 2057 4 times, leaving a remainder of 377.
The number 4 becomes the next digit in our result. 
Result so far: 234.0
Subtracting 1680 from 2057 leaves us with 377.
Bring next digit (5) of the dividend behind the 377 and repeat the process: 3775 / 420

Moving on to step 6:
420 can be fit into 3775 8 times, resulting in a remainder of 415.
Write down 8 as next digit of the result. 
Result so far: 2348.0
Subtract 3360 from 3775 to get 415.
Include the next digit (8) from the dividend after 415, then repeat: 4158 / 420

Advancing to step 7:
4158 divided by 420 is 9 with a remainder of 378.
The number 9 becomes the next digit in our result. 
Result so far: 23489.0
Subtracting 3780 from 4158 leaves us with 378.
Fetch the next digit (4) from the dividend, attach it to 378 and continue: 3784 / 420

Advancing to step 8:
The number 420 fits into 3784 9 times, leaving a remainder of 4.
Record the quotient 9 as the next digit in the result. 
Result so far: 234899.0
Subtract 3780 from 3784 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Step 9:
When dividing 40 by 420, we get 0 with a remainder of 40.
The number 0 becomes the next digit in our result. 
Result so far: 234899.0
The remainder is 40 after subtracting 0 from 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 10:
420 can be fit into 400 0 times, resulting in a remainder of 400.
Record the quotient 0 as the next digit in the result. 
Result so far: 234899.0
The remainder is 400 after subtracting 0 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

After the division, we end up with 234899.0 and a remainder of 0.4.
