We look at the division of 54452774 by 390 
Let's see how many times 390 fits into 54452774.

Let's proceed to step 1:
When dividing 5 by 390, we get 0 with a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Include the next digit (4) from the dividend after 5, then repeat: 54 / 390

Moving on to step 2:
54 divided by 390 is 0 with a remainder of 54.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 54 leaves us with 54.
Grab the next digit (4) from the dividend, add it to 54, then carry on: 544 / 390

Step 3:
390 can be fit into 544 1 times, resulting in a remainder of 154.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we take 390 away from 544, we end up with 154.
Grab the next digit (5) from the dividend, add it to 154, then carry on: 1545 / 390

Going ahead to step 4:
1545 divided by 390 is 3 with a remainder of 375.
Write down 3 as next digit of the result. 
Result so far: 13.0
Subtract 1170 from 1545 to get 375.
Fetch the next digit (2) from the dividend, attach it to 375 and continue: 3752 / 390

Let's proceed to step 5:
When dividing 3752 by 390, we get 9 with a remainder of 242.
Record the quotient 9 as the next digit in the result. 
Result so far: 139.0
If we subtract 3510 from 3752, we get 242.
Fetch the next digit (7) from the dividend, attach it to 242 and continue: 2427 / 390

Step 6:
2427 divided by 390 is 6 with a remainder of 87.
Use 6 as the next digit of our solution. 
Result so far: 1396.0
If we subtract 2340 from 2427, we get 87.
Grab the next digit (7) from the dividend, add it to 87, then carry on: 877 / 390

On to step 7:
877 divided by 390 is 2 with a remainder of 97.
Write down 2 as next digit of the result. 
Result so far: 13962.0
If we subtract 780 from 877, we get 97.
Take the next digit (4) from the dividend and append it to 97, then repeat: 974 / 390

Let's proceed to step 8:
974 divided by 390 is 2 with a remainder of 194.
Write down 2 as next digit of the result. 
Result so far: 139622.0
Subtract 780 from 974 to get 194.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1940, and continue the process.

Going ahead to step 9:
The number 390 fits into 1940 4 times, leaving a remainder of 380.
Put 4 as the next digit of the answer. 
Result so far: 139622.4
If we take 1560 away from 1940, we end up with 380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3800, and continue the process.

Going ahead to step 10:
If we divide 3800 by 390, we get 9 and a remainder of 290.
The next digit of our result is 9. 
Result so far: 139622.49
Subtract 3510 from 3800 to get 290.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2900, and continue the process.

Going ahead to step 11:
If we divide 2900 by 390, we get 7 and a remainder of 170.
The number 7 becomes the next digit in our result. 
Result so far: 139622.497
If we subtract 2730 from 2900, we get 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1700, and continue the process.

Moving on to step 12:
The number 390 fits into 1700 4 times, leaving a remainder of 140.
Record the quotient 4 as the next digit in the result. 
Result so far: 139622.4974
If we take 1560 away from 1700, we end up with 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

Going ahead to step 13:
390 can be fit into 1400 3 times, resulting in a remainder of 230.
The number 3 becomes the next digit in our result. 
Result so far: 139622.49743
Subtract 1170 from 1400 to get 230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2300, and continue the process.

Going ahead to step 14:
390 can be fit into 2300 5 times, resulting in a remainder of 350.
Put 5 as the next digit of the answer. 
Result so far: 139622.497435
The remainder is 350 after subtracting 1950 from 2300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3500, and continue the process.

On to step 15:
If we divide 3500 by 390, we get 8 and a remainder of 380.
The next digit of our result is 8. 
Result so far: 139622.4974358
If we subtract 3120 from 3500, we get 380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3800, and continue the process.

Going ahead to step 16:
If we divide 3800 by 390, we get 9 and a remainder of 290.
Write down 9 as next digit of the result. 
Result so far: 139622.49743589
Deduct 3510 from 3800 and we're left with 290.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2900, and continue the process.

After the division, we end up with 139622.49743589 and a remainder of 2.9e-07.
