We look at the division of 64939215 by 145 
We want to figure out the number of times 64939215 can be divided by 145.

Let's proceed to step 1:
145 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
The remainder is 6 after subtracting 0 from 6.
Grab the next digit (4) from the dividend, add it to 6, then carry on: 64 / 145

Going ahead to step 2:
If we divide 64 by 145, we get 0 and a remainder of 64.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 64 leaves us with 64.
Include the next digit (9) from the dividend after 64, then repeat: 649 / 145

Moving on to step 3:
145 can be fit into 649 4 times, resulting in a remainder of 69.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
Subtract 580 from 649 to get 69.
Append the next digit (3) from the dividend to 69 and continue with: 693 / 145

Let's proceed to step 4:
The number 145 fits into 693 4 times, leaving a remainder of 113.
Put 4 as the next digit of the answer. 
Result so far: 44.0
If we take 580 away from 693, we end up with 113.
Grab the next digit (9) from the dividend, add it to 113, then carry on: 1139 / 145

Step 5:
1139 divided by 145 is 7 with a remainder of 124.
The next digit of our result is 7. 
Result so far: 447.0
The remainder is 124 after subtracting 1015 from 1139.
Include the next digit (2) from the dividend after 124, then repeat: 1242 / 145

On to step 6:
1242 divided by 145 is 8 with a remainder of 82.
Use 8 as the next digit of our solution. 
Result so far: 4478.0
If we take 1160 away from 1242, we end up with 82.
Fetch the next digit (1) from the dividend, attach it to 82 and continue: 821 / 145

Step 7:
145 goes into 821 5 times with a remainder of 96.
Put 5 as the next digit of the answer. 
Result so far: 44785.0
Deduct 725 from 821 and we're left with 96.
Include the next digit (5) from the dividend after 96, then repeat: 965 / 145

On to step 8:
145 can be fit into 965 6 times, resulting in a remainder of 95.
The number 6 becomes the next digit in our result. 
Result so far: 447856.0
The remainder is 95 after subtracting 870 from 965.
Since there are no more digits in the dividend, we add a zero to the remainder making it 950, and continue the process.

On to step 9:
When dividing 950 by 145, we get 6 with a remainder of 80.
Record the quotient 6 as the next digit in the result. 
Result so far: 447856.6
The remainder is 80 after subtracting 870 from 950.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Let's proceed to step 10:
When dividing 800 by 145, we get 5 with a remainder of 75.
The next digit of our result is 5. 
Result so far: 447856.65
If we take 725 away from 800, we end up with 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Let's proceed to step 11:
145 goes into 750 5 times with a remainder of 25.
Use 5 as the next digit of our solution. 
Result so far: 447856.655
Subtracting 725 from 750 leaves us with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Our division results in 447856.655 with a remaining 0.0025.
