We look at the division of 8309621 by 424 
We want to divide 8309621 by 424.

Going ahead to step 1:
8 divided by 424 is 0 with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Grab the next digit (3) from the dividend, add it to 8, then carry on: 83 / 424

Step 2:
If we divide 83 by 424, we get 0 and a remainder of 83.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 83 to get 83.
Take the next digit (0) from the dividend and append it to 83, then repeat: 830 / 424

Let's proceed to step 3:
424 can be fit into 830 1 times, resulting in a remainder of 406.
The next digit of our result is 1. 
Result so far: 1.0
If we subtract 424 from 830, we get 406.
Include the next digit (9) from the dividend after 406, then repeat: 4069 / 424

Step 4:
424 can be fit into 4069 9 times, resulting in a remainder of 253.
Record the quotient 9 as the next digit in the result. 
Result so far: 19.0
If we subtract 3816 from 4069, we get 253.
Take the next digit (6) from the dividend and append it to 253, then repeat: 2536 / 424

Advancing to step 5:
2536 divided by 424 is 5 with a remainder of 416.
The next digit of our result is 5. 
Result so far: 195.0
Subtracting 2120 from 2536 leaves us with 416.
Append the next digit (2) from the dividend to 416 and continue with: 4162 / 424

Step 6:
When dividing 4162 by 424, we get 9 with a remainder of 346.
Put 9 as the next digit of the answer. 
Result so far: 1959.0
Deduct 3816 from 4162 and we're left with 346.
Take the next digit (1) from the dividend and append it to 346, then repeat: 3461 / 424

Moving on to step 7:
The number 424 fits into 3461 8 times, leaving a remainder of 69.
Use 8 as the next digit of our solution. 
Result so far: 19598.0
If we take 3392 away from 3461, we end up with 69.
Since there are no more digits in the dividend, we add a zero to the remainder making it 690, and continue the process.

Step 8:
690 divided by 424 is 1 with a remainder of 266.
Put 1 as the next digit of the answer. 
Result so far: 19598.1
The remainder is 266 after subtracting 424 from 690.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2660, and continue the process.

On to step 9:
424 can be fit into 2660 6 times, resulting in a remainder of 116.
The number 6 becomes the next digit in our result. 
Result so far: 19598.16
Subtracting 2544 from 2660 leaves us with 116.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1160, and continue the process.

Moving on to step 10:
When dividing 1160 by 424, we get 2 with a remainder of 312.
The next digit of our result is 2. 
Result so far: 19598.162
The remainder is 312 after subtracting 848 from 1160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3120, and continue the process.

Advancing to step 11:
3120 divided by 424 is 7 with a remainder of 152.
Put 7 as the next digit of the answer. 
Result so far: 19598.1627
The remainder is 152 after subtracting 2968 from 3120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1520, and continue the process.

Advancing to step 12:
1520 divided by 424 is 3 with a remainder of 248.
Record the quotient 3 as the next digit in the result. 
Result so far: 19598.16273
If we take 1272 away from 1520, we end up with 248.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2480, and continue the process.

Advancing to step 13:
2480 divided by 424 is 5 with a remainder of 360.
The next digit of our result is 5. 
Result so far: 19598.162735
Subtract 2120 from 2480 to get 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3600, and continue the process.

Advancing to step 14:
When dividing 3600 by 424, we get 8 with a remainder of 208.
Use 8 as the next digit of our solution. 
Result so far: 19598.1627358
Subtract 3392 from 3600 to get 208.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2080, and continue the process.

Moving on to step 15:
2080 divided by 424 is 4 with a remainder of 384.
Put 4 as the next digit of the answer. 
Result so far: 19598.16273584
If we take 1696 away from 2080, we end up with 384.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3840, and continue the process.

The quotient of the division is 19598.16273584, and the remainder is 3.84e-07.
