We're dividing 7858108 by 248 
We want to divide 7858108 by 248.

On to step 1:
248 goes into 7 0 times with a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Bring next digit (8) of the dividend behind the 7 and repeat the process: 78 / 248

Moving on to step 2:
248 goes into 78 0 times with a remainder of 78.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 78, we get 78.
Take the next digit (5) from the dividend and append it to 78, then repeat: 785 / 248

Advancing to step 3:
248 can be fit into 785 3 times, resulting in a remainder of 41.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
The remainder is 41 after subtracting 744 from 785.
Include the next digit (8) from the dividend after 41, then repeat: 418 / 248

On to step 4:
When dividing 418 by 248, we get 1 with a remainder of 170.
Write down 1 as next digit of the result. 
Result so far: 31.0
The remainder is 170 after subtracting 248 from 418.
Include the next digit (1) from the dividend after 170, then repeat: 1701 / 248

Going ahead to step 5:
1701 divided by 248 is 6 with a remainder of 213.
Put 6 as the next digit of the answer. 
Result so far: 316.0
If we take 1488 away from 1701, we end up with 213.
Append the next digit (0) from the dividend to 213 and continue with: 2130 / 248

Step 6:
The number 248 fits into 2130 8 times, leaving a remainder of 146.
Put 8 as the next digit of the answer. 
Result so far: 3168.0
Deduct 1984 from 2130 and we're left with 146.
Take the next digit (8) from the dividend and append it to 146, then repeat: 1468 / 248

Moving on to step 7:
If we divide 1468 by 248, we get 5 and a remainder of 228.
The next digit of our result is 5. 
Result so far: 31685.0
If we subtract 1240 from 1468, we get 228.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2280, and continue the process.

Advancing to step 8:
When dividing 2280 by 248, we get 9 with a remainder of 48.
Write down 9 as next digit of the result. 
Result so far: 31685.9
Deduct 2232 from 2280 and we're left with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Going ahead to step 9:
The number 248 fits into 480 1 times, leaving a remainder of 232.
Record the quotient 1 as the next digit in the result. 
Result so far: 31685.91
Subtract 248 from 480 to get 232.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2320, and continue the process.

Going ahead to step 10:
If we divide 2320 by 248, we get 9 and a remainder of 88.
The next digit of our result is 9. 
Result so far: 31685.919
The remainder is 88 after subtracting 2232 from 2320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 880, and continue the process.

Step 11:
The number 248 fits into 880 3 times, leaving a remainder of 136.
Write down 3 as next digit of the result. 
Result so far: 31685.9193
The remainder is 136 after subtracting 744 from 880.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1360, and continue the process.

Going ahead to step 12:
The number 248 fits into 1360 5 times, leaving a remainder of 120.
The number 5 becomes the next digit in our result. 
Result so far: 31685.91935
The remainder is 120 after subtracting 1240 from 1360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Moving on to step 13:
When dividing 1200 by 248, we get 4 with a remainder of 208.
Write down 4 as next digit of the result. 
Result so far: 31685.919354
The remainder is 208 after subtracting 992 from 1200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2080, and continue the process.

Let's proceed to step 14:
The number 248 fits into 2080 8 times, leaving a remainder of 96.
Record the quotient 8 as the next digit in the result. 
Result so far: 31685.9193548
Subtract 1984 from 2080 to 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.

On to step 15:
960 divided by 248 is 3 with a remainder of 216.
Use 3 as the next digit of our solution. 
Result so far: 31685.91935483
Deduct 744 from 960 and we're left with 216.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2160, and continue the process.

After the division, we end up with 31685.91935483 and a remainder of 2.16e-07.
