We look at the division of 423319 by 89 
We're looking to find how many times 89 goes into 423319.

Going ahead to step 1:
The number 89 fits into 4 0 times, leaving a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Include the next digit (2) from the dividend after 4, then repeat: 42 / 89

Advancing to step 2:
If we divide 42 by 89, we get 0 and a remainder of 42.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 42, we end up with 42.
Include the next digit (3) from the dividend after 42, then repeat: 423 / 89

Advancing to step 3:
89 goes into 423 4 times with a remainder of 67.
Write down 4 as next digit of the result. 
Result so far: 4.0
Deduct 356 from 423 and we're left with 67.
Take the next digit (3) from the dividend and append it to 67, then repeat: 673 / 89

Moving on to step 4:
89 goes into 673 7 times with a remainder of 50.
The number 7 becomes the next digit in our result. 
Result so far: 47.0
Subtract 623 from 673 to get 50.
Grab the next digit (1) from the dividend, add it to 50, then carry on: 501 / 89

Step 5:
89 can be fit into 501 5 times, resulting in a remainder of 56.
Write down 5 as next digit of the result. 
Result so far: 475.0
If we subtract 445 from 501, we get 56.
Take the next digit (9) from the dividend and append it to 56, then repeat: 569 / 89

Let's proceed to step 6:
If we divide 569 by 89, we get 6 and a remainder of 35.
The next digit of our result is 6. 
Result so far: 4756.0
If we take 534 away from 569, we end up with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Let's proceed to step 7:
If we divide 350 by 89, we get 3 and a remainder of 83.
The number 3 becomes the next digit in our result. 
Result so far: 4756.3
Subtract 267 from 350 to get 83.
Since there are no more digits in the dividend, we add a zero to the remainder making it 830, and continue the process.

Let's proceed to step 8:
89 goes into 830 9 times with a remainder of 29.
The next digit of our result is 9. 
Result so far: 4756.39
If we subtract 801 from 830, we get 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

On to step 9:
The number 89 fits into 290 3 times, leaving a remainder of 23.
Write down 3 as next digit of the result. 
Result so far: 4756.393
If we subtract 267 from 290, we get 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Let's proceed to step 10:
The number 89 fits into 230 2 times, leaving a remainder of 52.
Write down 2 as next digit of the result. 
Result so far: 4756.3932
Subtracting 178 from 230 leaves us with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Going ahead to step 11:
520 divided by 89 is 5 with a remainder of 75.
Write down 5 as next digit of the result. 
Result so far: 4756.39325
Subtract 445 from 520 to get 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Moving on to step 12:
750 divided by 89 is 8 with a remainder of 38.
Record the quotient 8 as the next digit in the result. 
Result so far: 4756.393258
Subtracting 712 from 750 leaves us with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Step 13:
89 can be fit into 380 4 times, resulting in a remainder of 24.
Use 4 as the next digit of our solution. 
Result so far: 4756.3932584
Subtracting 356 from 380 leaves us with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Going ahead to step 14:
240 divided by 89 is 2 with a remainder of 62.
The next digit of our result is 2. 
Result so far: 4756.39325842
The remainder is 62 after subtracting 178 from 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Our division results in 4756.39325842 with a remaining 6.2e-08.
