640489 divided by 58 
We want to figure out the number of times 640489 can be divided by 58.

Let's proceed to step 1:
58 goes into 6 0 times with a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Bring next digit (4) of the dividend behind the 6 and repeat the process: 64 / 58

Let's proceed to step 2:
If we divide 64 by 58, we get 1 and a remainder of 6.
Put 1 as the next digit of the answer. 
Result so far: 1.0
The remainder is 6 after subtracting 58 from 64.
Append the next digit (0) from the dividend to 6 and continue with: 60 / 58

Moving on to step 3:
60 divided by 58 is 1 with a remainder of 2.
Record the quotient 1 as the next digit in the result. 
Result so far: 11.0
The remainder is 2 after subtracting 58 from 60.
Append the next digit (4) from the dividend to 2 and continue with: 24 / 58

Moving on to step 4:
24 divided by 58 is 0 with a remainder of 24.
The next digit of our result is 0. 
Result so far: 110.0
Deduct 0 from 24 and we're left with 24.
Take the next digit (8) from the dividend and append it to 24, then repeat: 248 / 58

Let's proceed to step 5:
248 divided by 58 is 4 with a remainder of 16.
Use 4 as the next digit of our solution. 
Result so far: 1104.0
If we take 232 away from 248, we end up with 16.
Fetch the next digit (9) from the dividend, attach it to 16 and continue: 169 / 58

Let's proceed to step 6:
If we divide 169 by 58, we get 2 and a remainder of 53.
The next digit of our result is 2. 
Result so far: 11042.0
Subtract 116 from 169 to get 53.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

Going ahead to step 7:
58 can be fit into 530 9 times, resulting in a remainder of 8.
Write down 9 as next digit of the result. 
Result so far: 11042.9
Subtracting 522 from 530 leaves us with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Step 8:
58 goes into 80 1 times with a remainder of 22.
The number 1 becomes the next digit in our result. 
Result so far: 11042.91
If we take 58 away from 80, 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.

Going ahead to step 9:
220 divided by 58 is 3 with a remainder of 46.
The next digit of our result is 3. 
Result so far: 11042.913
The remainder is 46 after subtracting 174 from 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Advancing to step 10:
The number 58 fits into 460 7 times, leaving a remainder of 54.
The next digit of our result is 7. 
Result so far: 11042.9137
The remainder is 54 after subtracting 406 from 460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Step 11:
540 divided by 58 is 9 with a remainder of 18.
The next digit of our result is 9. 
Result so far: 11042.91379
The remainder is 18 after subtracting 522 from 540.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Let's proceed to step 12:
180 divided by 58 is 3 with a remainder of 6.
Use 3 as the next digit of our solution. 
Result so far: 11042.913793
The remainder is 6 after subtracting 174 from 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Moving on to step 13:
58 can be fit into 60 1 times, resulting in a remainder of 2.
Record the quotient 1 as the next digit in the result. 
Result so far: 11042.9137931
If we subtract 58 from 60, we get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Step 14:
The number 58 fits into 20 0 times, leaving a remainder of 20.
Use 0 as the next digit of our solution. 
Result so far: 11042.9137931
Subtracting 0 from 20 leaves us 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.

The final outcome is 11042.9137931, with a leftover of 2e-08.
