Let's divide 640437 by 89
Let's see how many times 89 fits into 640437.

On to step 1:
The number 89 fits into 6 0 times, leaving a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Include the next digit (4) from the dividend after 6, then repeat: 64 / 89

Advancing to step 2:
64 divided by 89 is 0 with a remainder of 64.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 64, we get 64.
Take the next digit (0) from the dividend and append it to 64, then repeat: 640 / 89

Moving on to step 3:
When dividing 640 by 89, we get 7 with a remainder of 17.
Record the quotient 7 as the next digit in the result. 
Result so far: 7.0
If we subtract 623 from 640, we get 17.
Fetch the next digit (4) from the dividend, attach it to 17 and continue: 174 / 89

Going ahead to step 4:
89 goes into 174 1 times with a remainder of 85.
Use 1 as the next digit of our solution. 
Result so far: 71.0
Subtract 89 from 174 to get 85.
Append the next digit (3) from the dividend to 85 and continue with: 853 / 89

On to step 5:
The number 89 fits into 853 9 times, leaving a remainder of 52.
The number 9 becomes the next digit in our result. 
Result so far: 719.0
Subtract 801 from 853 to get 52.
Append the next digit (7) from the dividend to 52 and continue with: 527 / 89

Going ahead to step 6:
89 goes into 527 5 times with a remainder of 82.
The number 5 becomes the next digit in our result. 
Result so far: 7195.0
If we subtract 445 from 527, we get 82.
Since there are no more digits in the dividend, we add a zero to the remainder making it 820, and continue the process.

Step 7:
89 goes into 820 9 times with a remainder of 19.
Use 9 as the next digit of our solution. 
Result so far: 7195.9
Subtract 801 from 820 to get 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Going ahead to step 8:
190 divided by 89 is 2 with a remainder of 12.
Write down 2 as next digit of the result. 
Result so far: 7195.92
If we subtract 178 from 190, we get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

On to step 9:
89 goes into 120 1 times with a remainder of 31.
Put 1 as the next digit of the answer. 
Result so far: 7195.921
Subtracting 89 from 120 leaves us with 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Moving on to step 10:
89 goes into 310 3 times with a remainder of 43.
Use 3 as the next digit of our solution. 
Result so far: 7195.9213
Subtracting 267 from 310 leaves us with 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Moving on to step 11:
When dividing 430 by 89, we get 4 with a remainder of 74.
The next digit of our result is 4. 
Result so far: 7195.92134
Subtract 356 from 430 to get 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

Moving on to step 12:
89 goes into 740 8 times with a remainder of 28.
Put 8 as the next digit of the answer. 
Result so far: 7195.921348
The remainder is 28 after subtracting 712 from 740.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Let's proceed to step 13:
280 divided by 89 is 3 with a remainder of 13.
Put 3 as the next digit of the answer. 
Result so far: 7195.9213483
Deduct 267 from 280 and we're left with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Moving on to step 14:
The number 89 fits into 130 1 times, leaving a remainder of 41.
The number 1 becomes the next digit in our result. 
Result so far: 7195.92134831
Deduct 89 from 130 and we're left with 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Our division results in 7195.92134831 with a remaining 4.1e-08.
