We're dividing 78403757 by 251 
We're looking to find how many times 251 goes into 78403757.

Advancing to step 1:
The number 251 fits into 7 0 times, leaving a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Append the next digit (8) from the dividend to 7 and continue with: 78 / 251

Moving on to step 2:
The number 251 fits into 78 0 times, leaving a remainder of 78.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 78, we get 78.
Include the next digit (4) from the dividend after 78, then repeat: 784 / 251

Step 3:
251 can be fit into 784 3 times, resulting in a remainder of 31.
The next digit of our result is 3. 
Result so far: 3.0
If we subtract 753 from 784, we get 31.
Bring next digit (0) of the dividend behind the 31 and repeat the process: 310 / 251

Going ahead to step 4:
If we divide 310 by 251, we get 1 and a remainder of 59.
Write down 1 as next digit of the result. 
Result so far: 31.0
Deduct 251 from 310 and we're left with 59.
Grab the next digit (3) from the dividend, add it to 59, then carry on: 593 / 251

Advancing to step 5:
The number 251 fits into 593 2 times, leaving a remainder of 91.
Write down 2 as next digit of the result. 
Result so far: 312.0
Deduct 502 from 593 and we're left with 91.
Include the next digit (7) from the dividend after 91, then repeat: 917 / 251

Let's proceed to step 6:
When dividing 917 by 251, we get 3 with a remainder of 164.
The number 3 becomes the next digit in our result. 
Result so far: 3123.0
Subtracting 753 from 917 leaves us with 164.
Grab the next digit (5) from the dividend, add it to 164, then carry on: 1645 / 251

Step 7:
1645 divided by 251 is 6 with a remainder of 139.
The number 6 becomes the next digit in our result. 
Result so far: 31236.0
Deduct 1506 from 1645 and we're left with 139.
Fetch the next digit (7) from the dividend, attach it to 139 and continue: 1397 / 251

Let's proceed to step 8:
251 can be fit into 1397 5 times, resulting in a remainder of 142.
Use 5 as the next digit of our solution. 
Result so far: 312365.0
The remainder is 142 after subtracting 1255 from 1397.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1420, and continue the process.

Step 9:
If we divide 1420 by 251, we get 5 and a remainder of 165.
The number 5 becomes the next digit in our result. 
Result so far: 312365.5
If we subtract 1255 from 1420, we get 165.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1650, and continue the process.

Advancing to step 10:
When dividing 1650 by 251, we get 6 with a remainder of 144.
Put 6 as the next digit of the answer. 
Result so far: 312365.56
Deduct 1506 from 1650 and we're left with 144.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1440, and continue the process.

Moving on to step 11:
When dividing 1440 by 251, we get 5 with a remainder of 185.
Record the quotient 5 as the next digit in the result. 
Result so far: 312365.565
If we subtract 1255 from 1440, we get 185.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1850, and continue the process.

Advancing to step 12:
If we divide 1850 by 251, we get 7 and a remainder of 93.
The next digit of our result is 7. 
Result so far: 312365.5657
Deduct 1757 from 1850 and we're left with 93.
Since there are no more digits in the dividend, we add a zero to the remainder making it 930, and continue the process.

Step 13:
The number 251 fits into 930 3 times, leaving a remainder of 177.
The number 3 becomes the next digit in our result. 
Result so far: 312365.56573
Deduct 753 from 930 and we're left with 177.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1770, and continue the process.

Let's proceed to step 14:
251 goes into 1770 7 times with a remainder of 13.
Record the quotient 7 as the next digit in the result. 
Result so far: 312365.565737
Subtracting 1757 from 1770 leaves us with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Let's proceed to step 15:
251 goes into 130 0 times with a remainder of 130.
Record the quotient 0 as the next digit in the result. 
Result so far: 312365.565737
Deduct 0 from 130 and we're left with 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

Let's proceed to step 16:
When dividing 1300 by 251, we get 5 with a remainder of 45.
The number 5 becomes the next digit in our result. 
Result so far: 312365.56573705
The remainder is 45 after subtracting 1255 from 1300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

The quotient of the division is 312365.56573705, and the remainder is 4.5e-08.
