We divide 63745887 by 259
We want to figure out the number of times 63745887 can be divided by 259.

Going ahead to step 1:
If we divide 6 by 259, we get 0 and a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Include the next digit (3) from the dividend after 6, then repeat: 63 / 259

On to step 2:
259 can be fit into 63 0 times, resulting in a remainder of 63.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 63, we end up with 63.
Append the next digit (7) from the dividend to 63 and continue with: 637 / 259

Advancing to step 3:
259 can be fit into 637 2 times, resulting in a remainder of 119.
The next digit of our result is 2. 
Result so far: 2.0
If we subtract 518 from 637, we get 119.
Bring next digit (4) of the dividend behind the 119 and repeat the process: 1194 / 259

Moving on to step 4:
The number 259 fits into 1194 4 times, leaving a remainder of 158.
Put 4 as the next digit of the answer. 
Result so far: 24.0
Deduct 1036 from 1194 and we're left with 158.
Take the next digit (5) from the dividend and append it to 158, then repeat: 1585 / 259

Going ahead to step 5:
259 goes into 1585 6 times with a remainder of 31.
The number 6 becomes the next digit in our result. 
Result so far: 246.0
Subtract 1554 from 1585 to get 31.
Include the next digit (8) from the dividend after 31, then repeat: 318 / 259

Going ahead to step 6:
When dividing 318 by 259, we get 1 with a remainder of 59.
Write down 1 as next digit of the result. 
Result so far: 2461.0
Deduct 259 from 318 and we're left with 59.
Include the next digit (8) from the dividend after 59, then repeat: 598 / 259

Let's proceed to step 7:
When dividing 598 by 259, we get 2 with a remainder of 80.
Use 2 as the next digit of our solution. 
Result so far: 24612.0
Deduct 518 from 598 and we're left with 80.
Fetch the next digit (7) from the dividend, attach it to 80 and continue: 807 / 259

On to step 8:
807 divided by 259 is 3 with a remainder of 30.
The next digit of our result is 3. 
Result so far: 246123.0
Subtracting 777 from 807 leaves us with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Going ahead to step 9:
When dividing 300 by 259, we get 1 with a remainder of 41.
Write down 1 as next digit of the result. 
Result so far: 246123.1
Subtract 259 from 300 to get 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Step 10:
410 divided by 259 is 1 with a remainder of 151.
Record the quotient 1 as the next digit in the result. 
Result so far: 246123.11
The remainder is 151 after subtracting 259 from 410.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1510, and continue the process.

The final outcome is 246123.11, with a leftover of 0.151.
