78344646 divided by 251 
We want to divide 78344646 by 251.

Let's proceed to step 1:
251 goes into 7 0 times with a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Append the next digit (8) from the dividend to 7 and continue with: 78 / 251

Step 2:
251 goes into 78 0 times with a remainder of 78.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 78 to get 78.
Grab the next digit (3) from the dividend, add it to 78, then carry on: 783 / 251

Step 3:
When dividing 783 by 251, we get 3 with a remainder of 30.
Put 3 as the next digit of the answer. 
Result so far: 3.0
The remainder is 30 after subtracting 753 from 783.
Grab the next digit (4) from the dividend, add it to 30, then carry on: 304 / 251

Advancing to step 4:
251 goes into 304 1 times with a remainder of 53.
Write down 1 as next digit of the result. 
Result so far: 31.0
Subtracting 251 from 304 leaves us with 53.
Fetch the next digit (4) from the dividend, attach it to 53 and continue: 534 / 251

Advancing to step 5:
251 can be fit into 534 2 times, resulting in a remainder of 32.
Put 2 as the next digit of the answer. 
Result so far: 312.0
If we take 502 away from 534, we end up with 32.
Bring next digit (6) of the dividend behind the 32 and repeat the process: 326 / 251

Moving on to step 6:
When dividing 326 by 251, we get 1 with a remainder of 75.
The number 1 becomes the next digit in our result. 
Result so far: 3121.0
Subtract 251 from 326 to get 75.
Fetch the next digit (4) from the dividend, attach it to 75 and continue: 754 / 251

Going ahead to step 7:
The number 251 fits into 754 3 times, leaving a remainder of 1.
Use 3 as the next digit of our solution. 
Result so far: 31213.0
Subtract 753 from 754 to get 1.
Append the next digit (6) from the dividend to 1 and continue with: 16 / 251

Going ahead to step 8:
If we divide 16 by 251, we get 0 and a remainder of 16.
The number 0 becomes the next digit in our result. 
Result so far: 312130.0
Subtract 0 from 16 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Moving on to step 9:
251 can be fit into 160 0 times, resulting in a remainder of 160.
The next digit of our result is 0. 
Result so far: 312130.0
The remainder is 160 after subtracting 0 from 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Let's proceed to step 10:
If we divide 1600 by 251, we get 6 and a remainder of 94.
Write down 6 as next digit of the result. 
Result so far: 312130.06
Subtract 1506 from 1600 to get 94.
Since there are no more digits in the dividend, we add a zero to the remainder making it 940, and continue the process.

Advancing to step 11:
The number 251 fits into 940 3 times, leaving a remainder of 187.
Put 3 as the next digit of the answer. 
Result so far: 312130.063
If we take 753 away from 940, we end up with 187.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1870, and continue the process.

Step 12:
251 goes into 1870 7 times with a remainder of 113.
Record the quotient 7 as the next digit in the result. 
Result so far: 312130.0637
If we take 1757 away from 1870, we end up with 113.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1130, and continue the process.

Going ahead to step 13:
If we divide 1130 by 251, we get 4 and a remainder of 126.
The next digit of our result is 4. 
Result so far: 312130.06374
Subtract 1004 from 1130 to get 126.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1260, and continue the process.

Moving on to step 14:
251 goes into 1260 5 times with a remainder of 5.
Use 5 as the next digit of our solution. 
Result so far: 312130.063745
Subtracting 1255 from 1260 leaves us with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Moving on to step 15:
50 divided by 251 is 0 with a remainder of 50.
Write down 0 as next digit of the result. 
Result so far: 312130.063745
If we subtract 0 from 50, we get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Step 16:
When dividing 500 by 251, we get 1 with a remainder of 249.
Write down 1 as next digit of the result. 
Result so far: 312130.06374501
If we take 251 away from 500, we end up with 249.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2490, and continue the process.

Our division results in 312130.06374501 with a remaining 2.49e-07.
