Let's divide 54442430 by 390
We want to divide 54442430 by 390.

On to step 1:
390 can be fit into 5 0 times, resulting in a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Append the next digit (4) from the dividend to 5 and continue with: 54 / 390

Let's proceed to step 2:
When dividing 54 by 390, we get 0 with a remainder of 54.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 54 leaves us with 54.
Take the next digit (4) from the dividend and append it to 54, then repeat: 544 / 390

Moving on to step 3:
The number 390 fits into 544 1 times, leaving a remainder of 154.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtracting 390 from 544 leaves us with 154.
Include the next digit (4) from the dividend after 154, then repeat: 1544 / 390

Step 4:
390 goes into 1544 3 times with a remainder of 374.
The number 3 becomes the next digit in our result. 
Result so far: 13.0
Deduct 1170 from 1544 and we're left with 374.
Append the next digit (2) from the dividend to 374 and continue with: 3742 / 390

Going ahead to step 5:
390 can be fit into 3742 9 times, resulting in a remainder of 232.
The number 9 becomes the next digit in our result. 
Result so far: 139.0
If we subtract 3510 from 3742, we get 232.
Grab the next digit (4) from the dividend, add it to 232, then carry on: 2324 / 390

On to step 6:
When dividing 2324 by 390, we get 5 with a remainder of 374.
Use 5 as the next digit of our solution. 
Result so far: 1395.0
Subtract 1950 from 2324 to get 374.
Append the next digit (3) from the dividend to 374 and continue with: 3743 / 390

Moving on to step 7:
If we divide 3743 by 390, we get 9 and a remainder of 233.
Record the quotient 9 as the next digit in the result. 
Result so far: 13959.0
If we subtract 3510 from 3743, we get 233.
Include the next digit (0) from the dividend after 233, then repeat: 2330 / 390

On to step 8:
390 goes into 2330 5 times with a remainder of 380.
Put 5 as the next digit of the answer. 
Result so far: 139595.0
Subtracting 1950 from 2330 leaves us 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.

Let's proceed to step 9:
The number 390 fits into 3800 9 times, leaving a remainder of 290.
Put 9 as the next digit of the answer. 
Result so far: 139595.9
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.

Moving on to step 10:
The number 390 fits into 2900 7 times, leaving a remainder of 170.
Put 7 as the next digit of the answer. 
Result so far: 139595.97
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.

Going ahead to step 11:
1700 divided by 390 is 4 with a remainder of 140.
Put 4 as the next digit of the answer. 
Result so far: 139595.974
Subtract 1560 from 1700 to get 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

On to step 12:
When dividing 1400 by 390, we get 3 with a remainder of 230.
Put 3 as the next digit of the answer. 
Result so far: 139595.9743
Deduct 1170 from 1400 and we're left with 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 13:
If we divide 2300 by 390, we get 5 and a remainder of 350.
The next digit of our result is 5. 
Result so far: 139595.97435
If we take 1950 away from 2300, we end up with 350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3500, and continue the process.

Advancing to step 14:
The number 390 fits into 3500 8 times, leaving a remainder of 380.
Write down 8 as next digit of the result. 
Result so far: 139595.974358
Deduct 3120 from 3500 and we're left 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 15:
When dividing 3800 by 390, we get 9 with a remainder of 290.
Record the quotient 9 as the next digit in the result. 
Result so far: 139595.9743589
Subtracting 3510 from 3800 leaves us 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.

On to step 16:
The number 390 fits into 2900 7 times, leaving a remainder of 170.
Write down 7 as next digit of the result. 
Result so far: 139595.97435897
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.

Our division results in 139595.97435897 with a remaining 1.7e-07.
