We look at the division of 64721952 by 251 
We want to divide 64721952 by 251.

Going ahead to step 1:
The number 251 fits into 6 0 times, leaving a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Take the next digit (4) from the dividend and append it to 6, then repeat: 64 / 251

Going ahead to step 2:
64 divided by 251 is 0 with a remainder of 64.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 64, we get 64.
Append the next digit (7) from the dividend to 64 and continue with: 647 / 251

Step 3:
251 can be fit into 647 2 times, resulting in a remainder of 145.
Write down 2 as next digit of the result. 
Result so far: 2.0
Subtract 502 from 647 to get 145.
Append the next digit (2) from the dividend to 145 and continue with: 1452 / 251

Advancing to step 4:
251 can be fit into 1452 5 times, resulting in a remainder of 197.
The number 5 becomes the next digit in our result. 
Result so far: 25.0
Deduct 1255 from 1452 and we're left with 197.
Bring next digit (1) of the dividend behind the 197 and repeat the process: 1971 / 251

Let's proceed to step 5:
When dividing 1971 by 251, we get 7 with a remainder of 214.
The number 7 becomes the next digit in our result. 
Result so far: 257.0
The remainder is 214 after subtracting 1757 from 1971.
Take the next digit (9) from the dividend and append it to 214, then repeat: 2149 / 251

Let's proceed to step 6:
2149 divided by 251 is 8 with a remainder of 141.
The number 8 becomes the next digit in our result. 
Result so far: 2578.0
Subtracting 2008 from 2149 leaves us with 141.
Take the next digit (5) from the dividend and append it to 141, then repeat: 1415 / 251

Let's proceed to step 7:
1415 divided by 251 is 5 with a remainder of 160.
Write down 5 as next digit of the result. 
Result so far: 25785.0
Subtracting 1255 from 1415 leaves us with 160.
Take the next digit (2) from the dividend and append it to 160, then repeat: 1602 / 251

Going ahead to step 8:
251 goes into 1602 6 times with a remainder of 96.
Write down 6 as next digit of the result. 
Result so far: 257856.0
If we subtract 1506 from 1602, we get 96.
Since there are no more digits in the dividend, we add a zero to the remainder making it 960, and continue the process.

Step 9:
If we divide 960 by 251, we get 3 and a remainder of 207.
The next digit of our result is 3. 
Result so far: 257856.3
Deduct 753 from 960 and we're left with 207.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2070, and continue the process.

Going ahead to step 10:
2070 divided by 251 is 8 with a remainder of 62.
The number 8 becomes the next digit in our result. 
Result so far: 257856.38
Subtracting 2008 from 2070 leaves us with 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

On to step 11:
620 divided by 251 is 2 with a remainder of 118.
Write down 2 as next digit of the result. 
Result so far: 257856.382
The remainder is 118 after subtracting 502 from 620.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1180, and continue the process.

Going ahead to step 12:
251 goes into 1180 4 times with a remainder of 176.
Write down 4 as next digit of the result. 
Result so far: 257856.3824
If we subtract 1004 from 1180, we get 176.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1760, and continue the process.

Step 13:
251 goes into 1760 7 times with a remainder of 3.
Write down 7 as next digit of the result. 
Result so far: 257856.38247
If we subtract 1757 from 1760, we get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Going ahead to step 14:
30 divided by 251 is 0 with a remainder of 30.
The number 0 becomes the next digit in our result. 
Result so far: 257856.38247
If we subtract 0 from 30, we get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

On to step 15:
300 divided by 251 is 1 with a remainder of 49.
Write down 1 as next digit of the result. 
Result so far: 257856.3824701
Subtract 251 from 300 to get 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Moving on to step 16:
251 can be fit into 490 1 times, resulting in a remainder of 239.
Use 1 as the next digit of our solution. 
Result so far: 257856.38247011
Subtract 251 from 490 to get 239.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2390, and continue the process.

The final outcome is 257856.38247011, with a leftover of 2.39e-07.
