31258820 ÷ 78 
Let's see how many times 78 fits into 31258820.

Step 1:
78 goes into 3 0 times with a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Fetch the next digit (1) from the dividend, attach it to 3 and continue: 31 / 78

Going ahead to step 2:
The number 78 fits into 31 0 times, leaving a remainder of 31.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 31, we get 31.
Append the next digit (2) from the dividend to 31 and continue with: 312 / 78

Going ahead to step 3:
When dividing 312 by 78, we get 4 with a remainder of 0.
Use 4 as the next digit of our solution. 
Result so far: 4.0
Subtract 312 from 312 to get 0.
Take the next digit (5) from the dividend and append it to 0, then repeat: 5 / 78

Step 4:
78 can be fit into 5 0 times, resulting in a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 40.0
If we take 0 away from 5, we end up with 5.
Grab the next digit (8) from the dividend, add it to 5, then carry on: 58 / 78

Going ahead to step 5:
78 goes into 58 0 times with a remainder of 58.
Write down 0 as next digit of the result. 
Result so far: 400.0
Subtracting 0 from 58 leaves us with 58.
Bring next digit (8) of the dividend behind the 58 and repeat the process: 588 / 78

Let's proceed to step 6:
588 divided by 78 is 7 with a remainder of 42.
Write down 7 as next digit of the result. 
Result so far: 4007.0
If we take 546 away from 588, we end up with 42.
Take the next digit (2) from the dividend and append it to 42, then repeat: 422 / 78

Going ahead to step 7:
422 divided by 78 is 5 with a remainder of 32.
Write down 5 as next digit of the result. 
Result so far: 40075.0
Subtract 390 from 422 to get 32.
Fetch the next digit (0) from the dividend, attach it to 32 and continue: 320 / 78

Advancing to step 8:
320 divided by 78 is 4 with a remainder of 8.
The number 4 becomes the next digit in our result. 
Result so far: 400754.0
Subtract 312 from 320 to get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Advancing to step 9:
80 divided by 78 is 1 with a remainder of 2.
The number 1 becomes the next digit in our result. 
Result so far: 400754.1
The remainder is 2 after subtracting 78 from 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Let's proceed to step 10:
78 goes into 20 0 times with a remainder of 20.
Put 0 as the next digit of the answer. 
Result so far: 400754.1
If we take 0 away from 20, we end up with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Going ahead to step 11:
78 can be fit into 200 2 times, resulting in a remainder of 44.
The number 2 becomes the next digit in our result. 
Result so far: 400754.102
Subtracting 156 from 200 leaves us with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Let's proceed to step 12:
78 goes into 440 5 times with a remainder of 50.
Use 5 as the next digit of our solution. 
Result so far: 400754.1025
Subtracting 390 from 440 leaves us with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Moving on to step 13:
500 divided by 78 is 6 with a remainder of 32.
The next digit of our result is 6. 
Result so far: 400754.10256
The remainder is 32 after subtracting 468 from 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Going ahead to step 14:
78 can be fit into 320 4 times, resulting in a remainder of 8.
Use 4 as the next digit of our solution. 
Result so far: 400754.102564
If we take 312 away from 320, we end up with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Moving on to step 15:
The number 78 fits into 80 1 times, leaving a remainder of 2.
Put 1 as the next digit of the answer. 
Result so far: 400754.1025641
If we take 78 away from 80, we end up with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Going ahead to step 16:
78 goes into 20 0 times with a remainder of 20.
Put 0 as the next digit of the answer. 
Result so far: 400754.1025641
Subtracting 0 from 20 leaves us with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

The quotient of the division is 400754.1025641, and the remainder is 2e-08.
