Let's divide 54877698 by 390
We're looking to find how many times 390 goes into 54877698.

Advancing to step 1:
390 goes into 5 0 times with a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Fetch the next digit (4) from the dividend, attach it to 5 and continue: 54 / 390

Let's proceed to step 2:
390 can be fit into 54 0 times, resulting in a remainder of 54.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 54 leaves us with 54.
Grab the next digit (8) from the dividend, add it to 54, then carry on: 548 / 390

Step 3:
390 goes into 548 1 times with a remainder of 158.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we subtract 390 from 548, we get 158.
Take the next digit (7) from the dividend and append it to 158, then repeat: 1587 / 390

On to step 4:
1587 divided by 390 is 4 with a remainder of 27.
Put 4 as the next digit of the answer. 
Result so far: 14.0
Subtracting 1560 from 1587 leaves us with 27.
Bring next digit (7) of the dividend behind the 27 and repeat the process: 277 / 390

Moving on to step 5:
277 divided by 390 is 0 with a remainder of 277.
Write down 0 as next digit of the result. 
Result so far: 140.0
Subtracting 0 from 277 leaves us with 277.
Grab the next digit (6) from the dividend, add it to 277, then carry on: 2776 / 390

Going ahead to step 6:
The number 390 fits into 2776 7 times, leaving a remainder of 46.
Put 7 as the next digit of the answer. 
Result so far: 1407.0
If we subtract 2730 from 2776, we get 46.
Fetch the next digit (9) from the dividend, attach it to 46 and continue: 469 / 390

Let's proceed to step 7:
469 divided by 390 is 1 with a remainder of 79.
Write down 1 as next digit of the result. 
Result so far: 14071.0
Deduct 390 from 469 and we're left with 79.
Fetch the next digit (8) from the dividend, attach it to 79 and continue: 798 / 390

Moving on to step 8:
When dividing 798 by 390, we get 2 with a remainder of 18.
The next digit of our result is 2. 
Result so far: 140712.0
Subtract 780 from 798 to get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

On to step 9:
When dividing 180 by 390, we get 0 with a remainder of 180.
The number 0 becomes the next digit in our result. 
Result so far: 140712.0
Subtract 0 from 180 to get 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

On to step 10:
1800 divided by 390 is 4 with a remainder of 240.
Use 4 as the next digit of our solution. 
Result so far: 140712.04
The remainder is 240 after subtracting 1560 from 1800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

Advancing to step 11:
390 can be fit into 2400 6 times, resulting in a remainder of 60.
Write down 6 as next digit of the result. 
Result so far: 140712.046
Subtracting 2340 from 2400 leaves us with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Let's proceed to step 12:
390 can be fit into 600 1 times, resulting in a remainder of 210.
Put 1 as the next digit of the answer. 
Result so far: 140712.0461
The remainder is 210 after subtracting 390 from 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2100, and continue the process.

Moving on to step 13:
2100 divided by 390 is 5 with a remainder of 150.
The next digit of our result is 5. 
Result so far: 140712.04615
Deduct 1950 from 2100 and we're left with 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

On to step 14:
When dividing 1500 by 390, we get 3 with a remainder of 330.
Put 3 as the next digit of the answer. 
Result so far: 140712.046153
Deduct 1170 from 1500 and we're left with 330.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3300, and continue the process.

Advancing to step 15:
The number 390 fits into 3300 8 times, leaving a remainder of 180.
The next digit of our result is 8. 
Result so far: 140712.0461538
The remainder is 180 after subtracting 3120 from 3300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

Going ahead to step 16:
390 goes into 1800 4 times with a remainder of 240.
Put 4 as the next digit of the answer. 
Result so far: 140712.04615384
The remainder is 240 after subtracting 1560 from 1800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

The final outcome is 140712.04615384, with a leftover of 2.4e-07.
