64574986 ÷ 102 
We're looking to find how many times 102 goes into 64574986.

Let's proceed to step 1:
The number 102 fits into 6 0 times, leaving a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Take the next digit (4) from the dividend and append it to 6, then repeat: 64 / 102

On to step 2:
64 divided by 102 is 0 with a remainder of 64.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 64 and we're left with 64.
Include the next digit (5) from the dividend after 64, then repeat: 645 / 102

Moving on to step 3:
The number 102 fits into 645 6 times, leaving a remainder of 33.
Put 6 as the next digit of the answer. 
Result so far: 6.0
If we subtract 612 from 645, we get 33.
Include the next digit (7) from the dividend after 33, then repeat: 337 / 102

Let's proceed to step 4:
337 divided by 102 is 3 with a remainder of 31.
Record the quotient 3 as the next digit in the result. 
Result so far: 63.0
Subtracting 306 from 337 leaves us with 31.
Take the next digit (4) from the dividend and append it to 31, then repeat: 314 / 102

Going ahead to step 5:
314 divided by 102 is 3 with a remainder of 8.
The next digit of our result is 3. 
Result so far: 633.0
Deduct 306 from 314 and we're left with 8.
Bring next digit (9) of the dividend behind the 8 and repeat the process: 89 / 102

On to step 6:
102 goes into 89 0 times with a remainder of 89.
Record the quotient 0 as the next digit in the result. 
Result so far: 6330.0
Subtract 0 from 89 to get 89.
Fetch the next digit (8) from the dividend, attach it to 89 and continue: 898 / 102

Advancing to step 7:
When dividing 898 by 102, we get 8 with a remainder of 82.
Write down 8 as next digit of the result. 
Result so far: 63308.0
If we take 816 away from 898, we end up with 82.
Fetch the next digit (6) from the dividend, attach it to 82 and continue: 826 / 102

Step 8:
826 divided by 102 is 8 with a remainder of 10.
Write down 8 as next digit of the result. 
Result so far: 633088.0
Subtract 816 from 826 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 9:
102 can be fit into 100 0 times, resulting in a remainder of 100.
Record the quotient 0 as the next digit in the result. 
Result so far: 633088.0
Deduct 0 from 100 and we're left with 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

On to step 10:
102 goes into 1000 9 times with a remainder of 82.
The next digit of our result is 9. 
Result so far: 633088.09
If we take 918 away from 1000, we end up with 82.
Since there are no more digits in the dividend, we add a zero to the remainder making it 820, and continue the process.

Advancing to step 11:
When dividing 820 by 102, we get 8 with a remainder of 4.
Use 8 as the next digit of our solution. 
Result so far: 633088.098
Deduct 816 from 820 and we're left with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

On to step 12:
102 can be fit into 40 0 times, resulting in a remainder of 40.
Record the quotient 0 as the next digit in the result. 
Result so far: 633088.098
The remainder is 40 after subtracting 0 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Moving on to step 13:
When dividing 400 by 102, we get 3 with a remainder of 94.
Record the quotient 3 as the next digit in the result. 
Result so far: 633088.09803
If we take 306 away from 400, we end up with 94.
Since there are no more digits in the dividend, we add a zero to the remainder making it 940, and continue the process.

Let's proceed to step 14:
102 goes into 940 9 times with a remainder of 22.
Put 9 as the next digit of the answer. 
Result so far: 633088.098039
Subtracting 918 from 940 leaves us 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.

Let's proceed to step 15:
When dividing 220 by 102, we get 2 with a remainder of 16.
Write down 2 as next digit of the result. 
Result so far: 633088.0980392
Subtract 204 from 220 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Let's proceed to step 16:
102 goes into 160 1 times with a remainder of 58.
Use 1 as the next digit of our solution. 
Result so far: 633088.09803921
If we subtract 102 from 160, we get 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

The final outcome is 633088.09803921, with a leftover of 5.8e-08.
