We're dividing 25302102 by 678 
We want to figure out the number of times 25302102 can be divided by 678.

Moving on to step 1:
2 divided by 678 is 0 with a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Append the next digit (5) from the dividend to 2 and continue with: 25 / 678

Moving on to step 2:
If we divide 25 by 678, we get 0 and a remainder of 25.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 25 to get 25.
Append the next digit (3) from the dividend to 25 and continue with: 253 / 678

Advancing to step 3:
678 can be fit into 253 0 times, resulting in a remainder of 253.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 253, we get 253.
Include the next digit (0) from the dividend after 253, then repeat: 2530 / 678

Advancing to step 4:
678 goes into 2530 3 times with a remainder of 496.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
Subtract 2034 from 2530 to get 496.
Take the next digit (2) from the dividend and append it to 496, then repeat: 4962 / 678

On to step 5:
When dividing 4962 by 678, we get 7 with a remainder of 216.
The number 7 becomes the next digit in our result. 
Result so far: 37.0
Subtract 4746 from 4962 to get 216.
Take the next digit (1) from the dividend and append it to 216, then repeat: 2161 / 678

Advancing to step 6:
When dividing 2161 by 678, we get 3 with a remainder of 127.
The number 3 becomes the next digit in our result. 
Result so far: 373.0
Deduct 2034 from 2161 and we're left with 127.
Append the next digit (0) from the dividend to 127 and continue with: 1270 / 678

Going ahead to step 7:
If we divide 1270 by 678, we get 1 and a remainder of 592.
Use 1 as the next digit of our solution. 
Result so far: 3731.0
Subtracting 678 from 1270 leaves us with 592.
Grab the next digit (2) from the dividend, add it to 592, then carry on: 5922 / 678

Step 8:
The number 678 fits into 5922 8 times, leaving a remainder of 498.
Write down 8 as next digit of the result. 
Result so far: 37318.0
Subtracting 5424 from 5922 leaves us with 498.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4980, and continue the process.

Going ahead to step 9:
When dividing 4980 by 678, we get 7 with a remainder of 234.
Record the quotient 7 as the next digit in the result. 
Result so far: 37318.7
Subtracting 4746 from 4980 leaves us with 234.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2340, and continue the process.

Going ahead to step 10:
When dividing 2340 by 678, we get 3 with a remainder of 306.
Record the quotient 3 as the next digit in the result. 
Result so far: 37318.73
Subtract 2034 from 2340 to get 306.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3060, and continue the process.

Step 11:
When dividing 3060 by 678, we get 4 with a remainder of 348.
The next digit of our result is 4. 
Result so far: 37318.734
Deduct 2712 from 3060 and we're left with 348.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3480, and continue the process.

Step 12:
678 can be fit into 3480 5 times, resulting in a remainder of 90.
The number 5 becomes the next digit in our result. 
Result so far: 37318.7345
Subtracting 3390 from 3480 leaves us with 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

Moving on to step 13:
678 can be fit into 900 1 times, resulting in a remainder of 222.
The number 1 becomes the next digit in our result. 
Result so far: 37318.73451
If we subtract 678 from 900, we get 222.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2220, and continue the process.

On to step 14:
When dividing 2220 by 678, we get 3 with a remainder of 186.
Record the quotient 3 as the next digit in the result. 
Result so far: 37318.734513
The remainder is 186 after subtracting 2034 from 2220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1860, and continue the process.

Going ahead to step 15:
When dividing 1860 by 678, we get 2 with a remainder of 504.
Use 2 as the next digit of our solution. 
Result so far: 37318.7345132
If we take 1356 away from 1860, we end up with 504.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5040, and continue the process.

Advancing to step 16:
678 goes into 5040 7 times with a remainder of 294.
Put 7 as the next digit of the answer. 
Result so far: 37318.73451327
Subtract 4746 from 5040 to get 294.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2940, and continue the process.

Our division results in 37318.73451327 with a remaining 2.94e-07.
