640627 divided by 89 
We want to figure out the number of times 640627 can be divided by 89.

Advancing to step 1:
89 goes into 6 0 times with a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Take the next digit (4) from the dividend and append it to 6, then repeat: 64 / 89

Step 2:
64 divided by 89 is 0 with a remainder of 64.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 64, we get 64.
Bring next digit (0) of the dividend behind the 64 and repeat the process: 640 / 89

Moving on to step 3:
When dividing 640 by 89, we get 7 with a remainder of 17.
The next digit of our result is 7. 
Result so far: 7.0
If we take 623 away from 640, we end up with 17.
Append the next digit (6) from the dividend to 17 and continue with: 176 / 89

On to step 4:
89 goes into 176 1 times with a remainder of 87.
Use 1 as the next digit of our solution. 
Result so far: 71.0
If we take 89 away from 176, we end up with 87.
Append the next digit (2) from the dividend to 87 and continue with: 872 / 89

Moving on to step 5:
89 can be fit into 872 9 times, resulting in a remainder of 71.
The number 9 becomes the next digit in our result. 
Result so far: 719.0
The remainder is 71 after subtracting 801 from 872.
Fetch the next digit (7) from the dividend, attach it to 71 and continue: 717 / 89

Let's proceed to step 6:
717 divided by 89 is 8 with a remainder of 5.
Write down 8 as next digit of the result. 
Result so far: 7198.0
The remainder is 5 after subtracting 712 from 717.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Going ahead to step 7:
The number 89 fits into 50 0 times, leaving a remainder of 50.
Use 0 as the next digit of our solution. 
Result so far: 7198.0
Subtract 0 from 50 to get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Going ahead to step 8:
The number 89 fits into 500 5 times, leaving a remainder of 55.
Write down 5 as next digit of the result. 
Result so far: 7198.05
Subtract 445 from 500 to get 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Advancing to step 9:
If we divide 550 by 89, we get 6 and a remainder of 16.
Use 6 as the next digit of our solution. 
Result so far: 7198.056
Subtracting 534 from 550 leaves us with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

On to step 10:
When dividing 160 by 89, we get 1 with a remainder of 71.
The next digit of our result is 1. 
Result so far: 7198.0561
Deduct 89 from 160 and we're left with 71.
Since there are no more digits in the dividend, we add a zero to the remainder making it 710, and continue the process.

Moving on to step 11:
When dividing 710 by 89, we get 7 with a remainder of 87.
Record the quotient 7 as the next digit in the result. 
Result so far: 7198.05617
If we subtract 623 from 710, we get 87.
Since there are no more digits in the dividend, we add a zero to the remainder making it 870, and continue the process.

Let's proceed to step 12:
870 divided by 89 is 9 with a remainder of 69.
Put 9 as the next digit of the answer. 
Result so far: 7198.056179
Deduct 801 from 870 and we're left with 69.
Since there are no more digits in the dividend, we add a zero to the remainder making it 690, and continue the process.

Let's proceed to step 13:
The number 89 fits into 690 7 times, leaving a remainder of 67.
Write down 7 as next digit of the result. 
Result so far: 7198.0561797
If we subtract 623 from 690, we get 67.
Since there are no more digits in the dividend, we add a zero to the remainder making it 670, and continue the process.

Step 14:
89 can be fit into 670 7 times, resulting in a remainder of 47.
Put 7 as the next digit of the answer. 
Result so far: 7198.05617977
If we subtract 623 from 670, we get 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

In conclusion, the division gives 7198.05617977 with a balance of 4.7e-08.
