64432858 ÷ 253 
We're looking to find how many times 253 goes into 64432858.

On to step 1:
When dividing 6 by 253, we get 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 / 253

Going ahead to step 2:
If we divide 64 by 253, 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.
Append the next digit (4) from the dividend to 64 and continue with: 644 / 253

Moving on to step 3:
253 can be fit into 644 2 times, resulting in a remainder of 138.
Use 2 as the next digit of our solution. 
Result so far: 2.0
If we take 506 away from 644, we end up with 138.
Bring next digit (3) of the dividend behind the 138 and repeat the process: 1383 / 253

On to step 4:
253 goes into 1383 5 times with a remainder of 118.
The number 5 becomes the next digit in our result. 
Result so far: 25.0
Subtracting 1265 from 1383 leaves us with 118.
Include the next digit (2) from the dividend after 118, then repeat: 1182 / 253

Going ahead to step 5:
1182 divided by 253 is 4 with a remainder of 170.
Record the quotient 4 as the next digit in the result. 
Result so far: 254.0
If we subtract 1012 from 1182, we get 170.
Bring next digit (8) of the dividend behind the 170 and repeat the process: 1708 / 253

On to step 6:
If we divide 1708 by 253, we get 6 and a remainder of 190.
Record the quotient 6 as the next digit in the result. 
Result so far: 2546.0
Subtracting 1518 from 1708 leaves us with 190.
Take the next digit (5) from the dividend and append it to 190, then repeat: 1905 / 253

Going ahead to step 7:
The number 253 fits into 1905 7 times, leaving a remainder of 134.
The number 7 becomes the next digit in our result. 
Result so far: 25467.0
If we take 1771 away from 1905, we end up with 134.
Fetch the next digit (8) from the dividend, attach it to 134 and continue: 1348 / 253

Step 8:
1348 divided by 253 is 5 with a remainder of 83.
The next digit of our result is 5. 
Result so far: 254675.0
Deduct 1265 from 1348 and we're left with 83.
Since there are no more digits in the dividend, we add a zero to the remainder making it 830, and continue the process.

Let's proceed to step 9:
830 divided by 253 is 3 with a remainder of 71.
Put 3 as the next digit of the answer. 
Result so far: 254675.3
If we subtract 759 from 830, we get 71.
Since there are no more digits in the dividend, we add a zero to the remainder making it 710, and continue the process.

Moving on to step 10:
710 divided by 253 is 2 with a remainder of 204.
The number 2 becomes the next digit in our result. 
Result so far: 254675.32
Subtracting 506 from 710 leaves us with 204.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2040, and continue the process.

Advancing to step 11:
253 goes into 2040 8 times with a remainder of 16.
Put 8 as the next digit of the answer. 
Result so far: 254675.328
The remainder is 16 after subtracting 2024 from 2040.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Going ahead to step 12:
When dividing 160 by 253, we get 0 with a remainder of 160.
The number 0 becomes the next digit in our result. 
Result so far: 254675.328
Subtract 0 from 160 to get 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Moving on to step 13:
The number 253 fits into 1600 6 times, leaving a remainder of 82.
Use 6 as the next digit of our solution. 
Result so far: 254675.32806
Deduct 1518 from 1600 and we're left 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.

Going ahead to step 14:
253 goes into 820 3 times with a remainder of 61.
Write down 3 as next digit of the result. 
Result so far: 254675.328063
Subtract 759 from 820 to get 61.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

Advancing to step 15:
610 divided by 253 is 2 with a remainder of 104.
Record the quotient 2 as the next digit in the result. 
Result so far: 254675.3280632
If we take 506 away from 610, we end up with 104.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1040, and continue the process.

Moving on to step 16:
When dividing 1040 by 253, we get 4 with a remainder of 28.
Put 4 as the next digit of the answer. 
Result so far: 254675.32806324
If we subtract 1012 from 1040, we get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

After the division, we end up with 254675.32806324 and a remainder of 2.8e-08.
