Let's divide 84876778 by 312
We want to figure out the number of times 84876778 can be divided by 312.

Let's proceed to step 1:
The number 312 fits into 8 0 times, leaving a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Grab the next digit (4) from the dividend, add it to 8, then carry on: 84 / 312

Going ahead to step 2:
312 goes into 84 0 times with a remainder of 84.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 84 and we're left with 84.
Fetch the next digit (8) from the dividend, attach it to 84 and continue: 848 / 312

Advancing to step 3:
312 can be fit into 848 2 times, resulting in a remainder of 224.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
The remainder is 224 after subtracting 624 from 848.
Grab the next digit (7) from the dividend, add it to 224, then carry on: 2247 / 312

Step 4:
312 goes into 2247 7 times with a remainder of 63.
Write down 7 as next digit of the result. 
Result so far: 27.0
Subtracting 2184 from 2247 leaves us with 63.
Grab the next digit (6) from the dividend, add it to 63, then carry on: 636 / 312

Let's proceed to step 5:
312 goes into 636 2 times with a remainder of 12.
The number 2 becomes the next digit in our result. 
Result so far: 272.0
Deduct 624 from 636 and we're left with 12.
Bring next digit (7) of the dividend behind the 12 and repeat the process: 127 / 312

On to step 6:
312 goes into 127 0 times with a remainder of 127.
Record the quotient 0 as the next digit in the result. 
Result so far: 2720.0
Subtract 0 from 127 to get 127.
Take the next digit (7) from the dividend and append it to 127, then repeat: 1277 / 312

Advancing to step 7:
1277 divided by 312 is 4 with a remainder of 29.
Write down 4 as next digit of the result. 
Result so far: 27204.0
If we take 1248 away from 1277, we end up with 29.
Include the next digit (8) from the dividend after 29, then repeat: 298 / 312

Moving on to step 8:
298 divided by 312 is 0 with a remainder of 298.
The number 0 becomes the next digit in our result. 
Result so far: 272040.0
The remainder is 298 after subtracting 0 from 298.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2980, and continue the process.

Moving on to step 9:
When dividing 2980 by 312, we get 9 with a remainder of 172.
Put 9 as the next digit of the answer. 
Result so far: 272040.9
Deduct 2808 from 2980 and we're left with 172.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1720, and continue the process.

Moving on to step 10:
The number 312 fits into 1720 5 times, leaving a remainder of 160.
Put 5 as the next digit of the answer. 
Result so far: 272040.95
Deduct 1560 from 1720 and we're left with 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 11:
The number 312 fits into 1600 5 times, leaving a remainder of 40.
Use 5 as the next digit of our solution. 
Result so far: 272040.955
If we subtract 1560 from 1600, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

In conclusion, the division gives 272040.955 with a balance of 0.004.
