Let's divide 64489912 by 462
We want to figure out the number of times 64489912 can be divided by 462.

Step 1:
6 divided by 462 is 0 with a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Fetch the next digit (4) from the dividend, attach it to 6 and continue: 64 / 462

Advancing to step 2:
If we divide 64 by 462, we get 0 and a remainder of 64.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 64, we get 64.
Fetch the next digit (4) from the dividend, attach it to 64 and continue: 644 / 462

Let's proceed to step 3:
462 can be fit into 644 1 times, resulting in a remainder of 182.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtracting 462 from 644 leaves us with 182.
Append the next digit (8) from the dividend to 182 and continue with: 1828 / 462

Moving on to step 4:
1828 divided by 462 is 3 with a remainder of 442.
Put 3 as the next digit of the answer. 
Result so far: 13.0
Subtract 1386 from 1828 to get 442.
Take the next digit (9) from the dividend and append it to 442, then repeat: 4429 / 462

On to step 5:
The number 462 fits into 4429 9 times, leaving a remainder of 271.
Write down 9 as next digit of the result. 
Result so far: 139.0
The remainder is 271 after subtracting 4158 from 4429.
Grab the next digit (9) from the dividend, add it to 271, then carry on: 2719 / 462

Advancing to step 6:
When dividing 2719 by 462, we get 5 with a remainder of 409.
Write down 5 as next digit of the result. 
Result so far: 1395.0
Subtract 2310 from 2719 to get 409.
Bring next digit (1) of the dividend behind the 409 and repeat the process: 4091 / 462

Going ahead to step 7:
If we divide 4091 by 462, we get 8 and a remainder of 395.
Use 8 as the next digit of our solution. 
Result so far: 13958.0
The remainder is 395 after subtracting 3696 from 4091.
Bring next digit (2) of the dividend behind the 395 and repeat the process: 3952 / 462

Going ahead to step 8:
462 can be fit into 3952 8 times, resulting in a remainder of 256.
The number 8 becomes the next digit in our result. 
Result so far: 139588.0
Deduct 3696 from 3952 and we're left with 256.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2560, and continue the process.

Going ahead to step 9:
When dividing 2560 by 462, we get 5 with a remainder of 250.
The next digit of our result is 5. 
Result so far: 139588.5
If we take 2310 away from 2560, we end up with 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2500, and continue the process.

Moving on to step 10:
When dividing 2500 by 462, we get 5 with a remainder of 190.
Write down 5 as next digit of the result. 
Result so far: 139588.55
If we subtract 2310 from 2500, we get 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1900, and continue the process.

The final result is 139588.55 with a remainder of 0.19.
