We divide 431665 by 89
Let's see how many times 89 fits into 431665.

Advancing to step 1:
89 can be fit into 4 0 times, resulting in a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Take the next digit (3) from the dividend and append it to 4, then repeat: 43 / 89

Advancing to step 2:
The number 89 fits into 43 0 times, leaving a remainder of 43.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 43 and we're left with 43.
Grab the next digit (1) from the dividend, add it to 43, then carry on: 431 / 89

Step 3:
431 divided by 89 is 4 with a remainder of 75.
Write down 4 as next digit of the result. 
Result so far: 4.0
Deduct 356 from 431 and we're left with 75.
Append the next digit (6) from the dividend to 75 and continue with: 756 / 89

On to step 4:
When dividing 756 by 89, we get 8 with a remainder of 44.
The number 8 becomes the next digit in our result. 
Result so far: 48.0
If we take 712 away from 756, we end up with 44.
Take the next digit (6) from the dividend and append it to 44, then repeat: 446 / 89

Moving on to step 5:
89 can be fit into 446 5 times, resulting in a remainder of 1.
Record the quotient 5 as the next digit in the result. 
Result so far: 485.0
The remainder is 1 after subtracting 445 from 446.
Bring next digit (5) of the dividend behind the 1 and repeat the process: 15 / 89

On to step 6:
15 divided by 89 is 0 with a remainder of 15.
The next digit of our result is 0. 
Result so far: 4850.0
If we subtract 0 from 15, we get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Step 7:
If we divide 150 by 89, we get 1 and a remainder of 61.
Use 1 as the next digit of our solution. 
Result so far: 4850.1
The remainder is 61 after subtracting 89 from 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

On to step 8:
610 divided by 89 is 6 with a remainder of 76.
Write down 6 as next digit of the result. 
Result so far: 4850.16
Deduct 534 from 610 and we're left with 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Moving on to step 9:
89 goes into 760 8 times with a remainder of 48.
The next digit of our result is 8. 
Result so far: 4850.168
Subtract 712 from 760 to get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Moving on to step 10:
89 can be fit into 480 5 times, resulting in a remainder of 35.
Put 5 as the next digit of the answer. 
Result so far: 4850.1685
The remainder is 35 after subtracting 445 from 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

On to step 11:
If we divide 350 by 89, we get 3 and a remainder of 83.
The next digit of our result is 3. 
Result so far: 4850.16853
The remainder is 83 after subtracting 267 from 350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 830, and continue the process.

On to step 12:
830 divided by 89 is 9 with a remainder of 29.
Write down 9 as next digit of the result. 
Result so far: 4850.168539
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 13:
89 goes into 290 3 times with a remainder of 23.
Put 3 as the next digit of the answer. 
Result so far: 4850.1685393
The remainder is 23 after subtracting 267 from 290.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Going ahead to step 14:
230 divided by 89 is 2 with a remainder of 52.
Put 2 as the next digit of the answer. 
Result so far: 4850.16853932
Deduct 178 from 230 and we're left 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.

The final outcome is 4850.16853932, with a leftover of 5.2e-08.
