We look at the division of 78813474 by 251 
We're looking to find how many times 251 goes into 78813474.

Step 1:
7 divided by 251 is 0 with a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Bring next digit (8) of the dividend behind the 7 and repeat the process: 78 / 251

Moving on to step 2:
78 divided by 251 is 0 with a remainder of 78.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 78 leaves us with 78.
Include the next digit (8) from the dividend after 78, then repeat: 788 / 251

On to step 3:
788 divided by 251 is 3 with a remainder of 35.
Write down 3 as next digit of the result. 
Result so far: 3.0
If we take 753 away from 788, we end up with 35.
Take the next digit (1) from the dividend and append it to 35, then repeat: 351 / 251

Moving on to step 4:
If we divide 351 by 251, we get 1 and a remainder of 100.
Put 1 as the next digit of the answer. 
Result so far: 31.0
Deduct 251 from 351 and we're left with 100.
Fetch the next digit (3) from the dividend, attach it to 100 and continue: 1003 / 251

Going ahead to step 5:
When dividing 1003 by 251, we get 3 with a remainder of 250.
The next digit of our result is 3. 
Result so far: 313.0
The remainder is 250 after subtracting 753 from 1003.
Include the next digit (4) from the dividend after 250, then repeat: 2504 / 251

Step 6:
251 can be fit into 2504 9 times, resulting in a remainder of 245.
The number 9 becomes the next digit in our result. 
Result so far: 3139.0
Subtract 2259 from 2504 to get 245.
Bring next digit (7) of the dividend behind the 245 and repeat the process: 2457 / 251

Moving on to step 7:
If we divide 2457 by 251, we get 9 and a remainder of 198.
Use 9 as the next digit of our solution. 
Result so far: 31399.0
Subtract 2259 from 2457 to get 198.
Bring next digit (4) of the dividend behind the 198 and repeat the process: 1984 / 251

Advancing to step 8:
When dividing 1984 by 251, we get 7 with a remainder of 227.
Put 7 as the next digit of the answer. 
Result so far: 313997.0
If we take 1757 away from 1984, we end up with 227.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2270, and continue the process.

Going ahead to step 9:
If we divide 2270 by 251, we get 9 and a remainder of 11.
Put 9 as the next digit of the answer. 
Result so far: 313997.9
Subtract 2259 from 2270 to get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Let's proceed to step 10:
The number 251 fits into 110 0 times, leaving a remainder of 110.
Record the quotient 0 as the next digit in the result. 
Result so far: 313997.9
The remainder is 110 after subtracting 0 from 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1100, and continue the process.

Step 11:
1100 divided by 251 is 4 with a remainder of 96.
Record the quotient 4 as the next digit in the result. 
Result so far: 313997.904
The remainder is 96 after subtracting 1004 from 1100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 960, and continue the process.

Step 12:
The number 251 fits into 960 3 times, leaving a remainder of 207.
Record the quotient 3 as the next digit in the result. 
Result so far: 313997.9043
Subtract 753 from 960 to get 207.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2070, and continue the process.

Moving on to step 13:
251 can be fit into 2070 8 times, resulting in a remainder of 62.
Put 8 as the next digit of the answer. 
Result so far: 313997.90438
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.

Let's proceed to step 14:
The number 251 fits into 620 2 times, leaving a remainder of 118.
The number 2 becomes the next digit in our result. 
Result so far: 313997.904382
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.

Step 15:
When dividing 1180 by 251, we get 4 with a remainder of 176.
Record the quotient 4 as the next digit in the result. 
Result so far: 313997.9043824
Deduct 1004 from 1180 and we're left with 176.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1760, and continue the process.

On to step 16:
251 can be fit into 1760 7 times, resulting in a remainder of 3.
Use 7 as the next digit of our solution. 
Result so far: 313997.90438247
If we take 1757 away from 1760, we end up with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

In conclusion, the division gives 313997.90438247 with a balance of 3e-09.
