We're dividing 64476061 by 258 
We want to figure out the number of times 64476061 can be divided by 258.

Step 1:
258 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.
Grab the next digit (4) from the dividend, add it to 6, then carry on: 64 / 258

Step 2:
When dividing 64 by 258, we get 0 with a remainder of 64.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 64, we end up with 64.
Grab the next digit (4) from the dividend, add it to 64, then carry on: 644 / 258

On to step 3:
258 can be fit into 644 2 times, resulting in a remainder of 128.
Write down 2 as next digit of the result. 
Result so far: 2.0
If we take 516 away from 644, we end up with 128.
Bring next digit (7) of the dividend behind the 128 and repeat the process: 1287 / 258

On to step 4:
The number 258 fits into 1287 4 times, leaving a remainder of 255.
Record the quotient 4 as the next digit in the result. 
Result so far: 24.0
Subtract 1032 from 1287 to get 255.
Take the next digit (6) from the dividend and append it to 255, then repeat: 2556 / 258

On to step 5:
2556 divided by 258 is 9 with a remainder of 234.
The next digit of our result is 9. 
Result so far: 249.0
If we subtract 2322 from 2556, we get 234.
Grab the next digit (0) from the dividend, add it to 234, then carry on: 2340 / 258

Step 6:
2340 divided by 258 is 9 with a remainder of 18.
Put 9 as the next digit of the answer. 
Result so far: 2499.0
The remainder is 18 after subtracting 2322 from 2340.
Bring next digit (6) of the dividend behind the 18 and repeat the process: 186 / 258

Let's proceed to step 7:
The number 258 fits into 186 0 times, leaving a remainder of 186.
The number 0 becomes the next digit in our result. 
Result so far: 24990.0
If we take 0 away from 186, we end up with 186.
Include the next digit (1) from the dividend after 186, then repeat: 1861 / 258

Going ahead to step 8:
When dividing 1861 by 258, we get 7 with a remainder of 55.
The next digit of our result is 7. 
Result so far: 249907.0
If we subtract 1806 from 1861, we 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.

Moving on to step 9:
258 can be fit into 550 2 times, resulting in a remainder of 34.
Put 2 as the next digit of the answer. 
Result so far: 249907.2
Subtract 516 from 550 to get 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Moving on to step 10:
258 can be fit into 340 1 times, resulting in a remainder of 82.
The number 1 becomes the next digit in our result. 
Result so far: 249907.21
The remainder is 82 after subtracting 258 from 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 820, and continue the process.

On to step 11:
When dividing 820 by 258, we get 3 with a remainder of 46.
Write down 3 as next digit of the result. 
Result so far: 249907.213
The remainder is 46 after subtracting 774 from 820.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Moving on to step 12:
When dividing 460 by 258, we get 1 with a remainder of 202.
Write down 1 as next digit of the result. 
Result so far: 249907.2131
If we take 258 away from 460, we end up with 202.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2020, and continue the process.

Let's proceed to step 13:
If we divide 2020 by 258, we get 7 and a remainder of 214.
Use 7 as the next digit of our solution. 
Result so far: 249907.21317
Deduct 1806 from 2020 and we're left with 214.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2140, and continue the process.

Advancing to step 14:
If we divide 2140 by 258, we get 8 and a remainder of 76.
Put 8 as the next digit of the answer. 
Result so far: 249907.213178
The remainder is 76 after subtracting 2064 from 2140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Step 15:
258 can be fit into 760 2 times, resulting in a remainder of 244.
The number 2 becomes the next digit in our result. 
Result so far: 249907.2131782
The remainder is 244 after subtracting 516 from 760.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2440, and continue the process.

Advancing to step 16:
258 can be fit into 2440 9 times, resulting in a remainder of 118.
Put 9 as the next digit of the answer. 
Result so far: 249907.21317829
The remainder is 118 after subtracting 2322 from 2440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1180, and continue the process.

After the division, we end up with 249907.21317829 and a remainder of 1.18e-07.
