We're dividing 4822215 by 421 
We want to figure out the number of times 4822215 can be divided by 421.

Step 1:
421 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
The remainder is 4 after subtracting 0 from 4.
Take the next digit (8) from the dividend and append it to 4, then repeat: 48 / 421

Moving on to step 2:
If we divide 48 by 421, we get 0 and a remainder of 48.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 48 to get 48.
Take the next digit (2) from the dividend and append it to 48, then repeat: 482 / 421

Advancing to step 3:
If we divide 482 by 421, we get 1 and a remainder of 61.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtract 421 from 482 to get 61.
Grab the next digit (2) from the dividend, add it to 61, then carry on: 612 / 421

Step 4:
When dividing 612 by 421, we get 1 with a remainder of 191.
The next digit of our result is 1. 
Result so far: 11.0
Deduct 421 from 612 and we're left with 191.
Append the next digit (2) from the dividend to 191 and continue with: 1912 / 421

Step 5:
421 can be fit into 1912 4 times, resulting in a remainder of 228.
The number 4 becomes the next digit in our result. 
Result so far: 114.0
If we subtract 1684 from 1912, we get 228.
Grab the next digit (1) from the dividend, add it to 228, then carry on: 2281 / 421

On to step 6:
421 can be fit into 2281 5 times, resulting in a remainder of 176.
The number 5 becomes the next digit in our result. 
Result so far: 1145.0
Subtracting 2105 from 2281 leaves us with 176.
Append the next digit (5) from the dividend to 176 and continue with: 1765 / 421

Let's proceed to step 7:
If we divide 1765 by 421, we get 4 and a remainder of 81.
Use 4 as the next digit of our solution. 
Result so far: 11454.0
Deduct 1684 from 1765 and we're left with 81.
Since there are no more digits in the dividend, we add a zero to the remainder making it 810, and continue the process.

Step 8:
If we divide 810 by 421, we get 1 and a remainder of 389.
Put 1 as the next digit of the answer. 
Result so far: 11454.1
Subtracting 421 from 810 leaves us with 389.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3890, and continue the process.

Let's proceed to step 9:
If we divide 3890 by 421, we get 9 and a remainder of 101.
Use 9 as the next digit of our solution. 
Result so far: 11454.19
The remainder is 101 after subtracting 3789 from 3890.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1010, and continue the process.

On to step 10:
421 can be fit into 1010 2 times, resulting in a remainder of 168.
Write down 2 as next digit of the result. 
Result so far: 11454.192
If we take 842 away from 1010, we end up with 168.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1680, and continue the process.

Step 11:
If we divide 1680 by 421, we get 3 and a remainder of 417.
The number 3 becomes the next digit in our result. 
Result so far: 11454.1923
If we take 1263 away from 1680, we end up with 417.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4170, and continue the process.

Advancing to step 12:
421 can be fit into 4170 9 times, resulting in a remainder of 381.
The number 9 becomes the next digit in our result. 
Result so far: 11454.19239
If we subtract 3789 from 4170, we get 381.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3810, and continue the process.

Moving on to step 13:
421 can be fit into 3810 9 times, resulting in a remainder of 21.
The next digit of our result is 9. 
Result so far: 11454.192399
Deduct 3789 from 3810 and we're left with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

In conclusion, the division gives 11454.192399 with a balance of 2.1e-06.
