We look at the division of 436640 by 89 
We want to figure out the number of times 436640 can be divided by 89.

Moving on to step 1:
When dividing 4 by 89, we get 0 with a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Append the next digit (3) from the dividend to 4 and continue with: 43 / 89

Moving on to step 2:
43 divided by 89 is 0 with a remainder of 43.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 43 leaves us with 43.
Take the next digit (6) from the dividend and append it to 43, then repeat: 436 / 89

Advancing to step 3:
89 can be fit into 436 4 times, resulting in a remainder of 80.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
If we take 356 away from 436, we end up with 80.
Fetch the next digit (6) from the dividend, attach it to 80 and continue: 806 / 89

Advancing to step 4:
If we divide 806 by 89, we get 9 and a remainder of 5.
Record the quotient 9 as the next digit in the result. 
Result so far: 49.0
Subtract 801 from 806 to get 5.
Fetch the next digit (4) from the dividend, attach it to 5 and continue: 54 / 89

On to step 5:
54 divided by 89 is 0 with a remainder of 54.
Write down 0 as next digit of the result. 
Result so far: 490.0
Deduct 0 from 54 and we're left with 54.
Take the next digit (0) from the dividend and append it to 54, then repeat: 540 / 89

Let's proceed to step 6:
540 divided by 89 is 6 with a remainder of 6.
Record the quotient 6 as the next digit in the result. 
Result so far: 4906.0
If we subtract 534 from 540, we get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

On to step 7:
The number 89 fits into 60 0 times, leaving a remainder of 60.
The number 0 becomes the next digit in our result. 
Result so far: 4906.0
Deduct 0 from 60 and we're left with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Going ahead to step 8:
600 divided by 89 is 6 with a remainder of 66.
The number 6 becomes the next digit in our result. 
Result so far: 4906.06
Subtract 534 from 600 to get 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

On to step 9:
89 goes into 660 7 times with a remainder of 37.
The next digit of our result is 7. 
Result so far: 4906.067
If we take 623 away from 660, we end up with 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Advancing to step 10:
89 can be fit into 370 4 times, resulting in a remainder of 14.
Write down 4 as next digit of the result. 
Result so far: 4906.0674
The remainder is 14 after subtracting 356 from 370.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Moving on to step 11:
If we divide 140 by 89, we get 1 and a remainder of 51.
The next digit of our result is 1. 
Result so far: 4906.06741
Subtract 89 from 140 to get 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

On to step 12:
The number 89 fits into 510 5 times, leaving a remainder of 65.
Record the quotient 5 as the next digit in the result. 
Result so far: 4906.067415
If we take 445 away from 510, we end up with 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

Advancing to step 13:
The number 89 fits into 650 7 times, leaving a remainder of 27.
Record the quotient 7 as the next digit in the result. 
Result so far: 4906.0674157
The remainder is 27 after subtracting 623 from 650.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Advancing to step 14:
When dividing 270 by 89, we get 3 with a remainder of 3.
Write down 3 as next digit of the result. 
Result so far: 4906.06741573
The remainder is 3 after subtracting 267 from 270.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

In conclusion, the division gives 4906.06741573 with a balance of 3e-09.
