We're dividing 400584 by 89 
Let's see how many times 89 fits into 400584.

On to step 1:
When dividing 4 by 89, we get 0 with a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Fetch the next digit (0) from the dividend, attach it to 4 and continue: 40 / 89

Advancing to step 2:
If we divide 40 by 89, we get 0 and a remainder of 40.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 40 to get 40.
Include the next digit (0) from the dividend after 40, then repeat: 400 / 89

Moving on to step 3:
The number 89 fits into 400 4 times, leaving a remainder of 44.
Write down 4 as next digit of the result. 
Result so far: 4.0
Subtract 356 from 400 to get 44.
Grab the next digit (5) from the dividend, add it to 44, then carry on: 445 / 89

Let's proceed to step 4:
89 can be fit into 445 5 times, resulting in a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 45.0
If we subtract 445 from 445, we get 0.
Fetch the next digit (8) from the dividend, attach it to 0 and continue: 8 / 89

Going ahead to step 5:
When dividing 8 by 89, we get 0 with a remainder of 8.
The next digit of our result is 0. 
Result so far: 450.0
Deduct 0 from 8 and we're left with 8.
Include the next digit (4) from the dividend after 8, then repeat: 84 / 89

On to step 6:
89 goes into 84 0 times with a remainder of 84.
Put 0 as the next digit of the answer. 
Result so far: 4500.0
If we subtract 0 from 84, we get 84.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

On to step 7:
When dividing 840 by 89, we get 9 with a remainder of 39.
Put 9 as the next digit of the answer. 
Result so far: 4500.9
The remainder is 39 after subtracting 801 from 840.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Moving on to step 8:
If we divide 390 by 89, we get 4 and a remainder of 34.
The next digit of our result is 4. 
Result so far: 4500.94
If we subtract 356 from 390, we get 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Let's proceed to step 9:
When dividing 340 by 89, we get 3 with a remainder of 73.
Record the quotient 3 as the next digit in the result. 
Result so far: 4500.943
Subtract 267 from 340 to get 73.
Since there are no more digits in the dividend, we add a zero to the remainder making it 730, and continue the process.

Let's proceed to step 10:
If we divide 730 by 89, we get 8 and a remainder of 18.
Put 8 as the next digit of the answer. 
Result so far: 4500.9438
If we take 712 away from 730, we end up with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Step 11:
89 goes into 180 2 times with a remainder of 2.
Use 2 as the next digit of our solution. 
Result so far: 4500.94382
The remainder is 2 after subtracting 178 from 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

On to step 12:
89 can be fit into 20 0 times, resulting in a remainder of 20.
Write down 0 as next digit of the result. 
Result so far: 4500.94382
Deduct 0 from 20 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.

Going ahead to step 13:
200 divided by 89 is 2 with a remainder of 22.
The next digit of our result is 2. 
Result so far: 4500.9438202
If we take 178 away from 200, we end up with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Let's proceed to step 14:
When dividing 220 by 89, we get 2 with a remainder of 42.
Record the quotient 2 as the next digit in the result. 
Result so far: 4500.94382022
Subtracting 178 from 220 leaves us with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Our division results in 4500.94382022 with a remaining 4.2e-08.
