Let's divide 96421058 by 420
We want to divide 96421058 by 420.

Step 1:
If we divide 9 by 420, we get 0 and a remainder of 9.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 9 after subtracting 0 from 9.
Include the next digit (6) from the dividend after 9, then repeat: 96 / 420

Going ahead to step 2:
96 divided by 420 is 0 with a remainder of 96.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 96 after subtracting 0 from 96.
Bring next digit (4) of the dividend behind the 96 and repeat the process: 964 / 420

Step 3:
964 divided by 420 is 2 with a remainder of 124.
Use 2 as the next digit of our solution. 
Result so far: 2.0
If we take 840 away from 964, we end up with 124.
Append the next digit (2) from the dividend to 124 and continue with: 1242 / 420

Step 4:
The number 420 fits into 1242 2 times, leaving a remainder of 402.
The next digit of our result is 2. 
Result so far: 22.0
Deduct 840 from 1242 and we're left with 402.
Include the next digit (1) from the dividend after 402, then repeat: 4021 / 420

Going ahead to step 5:
When dividing 4021 by 420, we get 9 with a remainder of 241.
Write down 9 as next digit of the result. 
Result so far: 229.0
If we take 3780 away from 4021, we end up with 241.
Append the next digit (0) from the dividend to 241 and continue with: 2410 / 420

Let's proceed to step 6:
When dividing 2410 by 420, we get 5 with a remainder of 310.
Put 5 as the next digit of the answer. 
Result so far: 2295.0
The remainder is 310 after subtracting 2100 from 2410.
Grab the next digit (5) from the dividend, add it to 310, then carry on: 3105 / 420

Advancing to step 7:
If we divide 3105 by 420, we get 7 and a remainder of 165.
Record the quotient 7 as the next digit in the result. 
Result so far: 22957.0
The remainder is 165 after subtracting 2940 from 3105.
Fetch the next digit (8) from the dividend, attach it to 165 and continue: 1658 / 420

Let's proceed to step 8:
If we divide 1658 by 420, we get 3 and a remainder of 398.
The next digit of our result is 3. 
Result so far: 229573.0
Subtracting 1260 from 1658 leaves us with 398.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3980, and continue the process.

Let's proceed to step 9:
420 goes into 3980 9 times with a remainder of 200.
The next digit of our result is 9. 
Result so far: 229573.9
Subtracting 3780 from 3980 leaves us with 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

On to step 10:
2000 divided by 420 is 4 with a remainder of 320.
Use 4 as the next digit of our solution. 
Result so far: 229573.94
Deduct 1680 from 2000 and we're left with 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

On to step 11:
When dividing 3200 by 420, we get 7 with a remainder of 260.
Write down 7 as next digit of the result. 
Result so far: 229573.947
Subtract 2940 from 3200 to get 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2600, and continue the process.

Let's proceed to step 12:
2600 divided by 420 is 6 with a remainder of 80.
Use 6 as the next digit of our solution. 
Result so far: 229573.9476
The remainder is 80 after subtracting 2520 from 2600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Step 13:
420 goes into 800 1 times with a remainder of 380.
Use 1 as the next digit of our solution. 
Result so far: 229573.94761
If we take 420 away from 800, we end up with 380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3800, and continue the process.

Let's proceed to step 14:
If we divide 3800 by 420, we get 9 and a remainder of 20.
Use 9 as the next digit of our solution. 
Result so far: 229573.947619
Deduct 3780 from 3800 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Advancing to step 15:
420 goes into 200 0 times with a remainder of 200.
The number 0 becomes the next digit in our result. 
Result so far: 229573.947619
Deduct 0 from 200 and we're left with 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

On to step 16:
The number 420 fits into 2000 4 times, leaving a remainder of 320.
Use 4 as the next digit of our solution. 
Result so far: 229573.94761904
Subtract 1680 from 2000 to get 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

The final outcome is 229573.94761904, with a leftover of 3.2e-07.
