8455313 divided by 423 
Our goal is to divide 8455313 by 423.

On to step 1:
The number 423 fits into 8 0 times, leaving a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Take the next digit (4) from the dividend and append it to 8, then repeat: 84 / 423

Let's proceed to step 2:
If we divide 84 by 423, we get 0 and a remainder of 84.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 84 to get 84.
Append the next digit (5) from the dividend to 84 and continue with: 845 / 423

Advancing to step 3:
845 divided by 423 is 1 with a remainder of 422.
Write down 1 as next digit of the result. 
Result so far: 1.0
Deduct 423 from 845 and we're left with 422.
Take the next digit (5) from the dividend and append it to 422, then repeat: 4225 / 423

On to step 4:
When dividing 4225 by 423, we get 9 with a remainder of 418.
Use 9 as the next digit of our solution. 
Result so far: 19.0
Deduct 3807 from 4225 and we're left with 418.
Grab the next digit (3) from the dividend, add it to 418, then carry on: 4183 / 423

On to step 5:
423 goes into 4183 9 times with a remainder of 376.
Record the quotient 9 as the next digit in the result. 
Result so far: 199.0
If we take 3807 away from 4183, we end up with 376.
Take the next digit (1) from the dividend and append it to 376, then repeat: 3761 / 423

Moving on to step 6:
When dividing 3761 by 423, we get 8 with a remainder of 377.
Write down 8 as next digit of the result. 
Result so far: 1998.0
Subtracting 3384 from 3761 leaves us with 377.
Include the next digit (3) from the dividend after 377, then repeat: 3773 / 423

Advancing to step 7:
When dividing 3773 by 423, we get 8 with a remainder of 389.
Use 8 as the next digit of our solution. 
Result so far: 19988.0
Subtracting 3384 from 3773 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.

Going ahead to step 8:
The number 423 fits into 3890 9 times, leaving a remainder of 83.
The number 9 becomes the next digit in our result. 
Result so far: 19988.9
Subtracting 3807 from 3890 leaves us with 83.
Since there are no more digits in the dividend, we add a zero to the remainder making it 830, and continue the process.

Advancing to step 9:
When dividing 830 by 423, we get 1 with a remainder of 407.
Record the quotient 1 as the next digit in the result. 
Result so far: 19988.91
If we take 423 away from 830, we end up with 407.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4070, and continue the process.

Going ahead to step 10:
423 can be fit into 4070 9 times, resulting in a remainder of 263.
The number 9 becomes the next digit in our result. 
Result so far: 19988.919
The remainder is 263 after subtracting 3807 from 4070.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2630, and continue the process.

On to step 11:
When dividing 2630 by 423, we get 6 with a remainder of 92.
The number 6 becomes the next digit in our result. 
Result so far: 19988.9196
Deduct 2538 from 2630 and we're left with 92.
Since there are no more digits in the dividend, we add a zero to the remainder making it 920, and continue the process.

On to step 12:
423 can be fit into 920 2 times, resulting in a remainder of 74.
The number 2 becomes the next digit in our result. 
Result so far: 19988.91962
If we take 846 away from 920, we end up with 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

Advancing to step 13:
423 goes into 740 1 times with a remainder of 317.
Put 1 as the next digit of the answer. 
Result so far: 19988.919621
If we subtract 423 from 740, we get 317.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3170, and continue the process.

Step 14:
423 goes into 3170 7 times with a remainder of 209.
Record the quotient 7 as the next digit in the result. 
Result so far: 19988.9196217
If we take 2961 away from 3170, we end up with 209.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2090, and continue the process.

Let's proceed to step 15:
If we divide 2090 by 423, we get 4 and a remainder of 398.
Write down 4 as next digit of the result. 
Result so far: 19988.91962174
Subtracting 1692 from 2090 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.

Our division results in 19988.91962174 with a remaining 3.98e-07.
