We look at the division of 45375680 by 390 
We're looking to find how many times 390 goes into 45375680.

On to step 1:
When dividing 4 by 390, we get 0 with a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Include the next digit (5) from the dividend after 4, then repeat: 45 / 390

Let's proceed to step 2:
When dividing 45 by 390, we get 0 with a remainder of 45.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 45, we get 45.
Bring next digit (3) of the dividend behind the 45 and repeat the process: 453 / 390

Moving on to step 3:
390 can be fit into 453 1 times, resulting in a remainder of 63.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtracting 390 from 453 leaves us with 63.
Grab the next digit (7) from the dividend, add it to 63, then carry on: 637 / 390

Advancing to step 4:
If we divide 637 by 390, we get 1 and a remainder of 247.
Use 1 as the next digit of our solution. 
Result so far: 11.0
If we take 390 away from 637, we end up with 247.
Append the next digit (5) from the dividend to 247 and continue with: 2475 / 390

Going ahead to step 5:
The number 390 fits into 2475 6 times, leaving a remainder of 135.
Record the quotient 6 as the next digit in the result. 
Result so far: 116.0
If we subtract 2340 from 2475, we get 135.
Fetch the next digit (6) from the dividend, attach it to 135 and continue: 1356 / 390

Step 6:
1356 divided by 390 is 3 with a remainder of 186.
Write down 3 as next digit of the result. 
Result so far: 1163.0
Subtracting 1170 from 1356 leaves us with 186.
Grab the next digit (8) from the dividend, add it to 186, then carry on: 1868 / 390

Moving on to step 7:
390 can be fit into 1868 4 times, resulting in a remainder of 308.
Record the quotient 4 as the next digit in the result. 
Result so far: 11634.0
Subtract 1560 from 1868 to get 308.
Include the next digit (0) from the dividend after 308, then repeat: 3080 / 390

On to step 8:
When dividing 3080 by 390, we get 7 with a remainder of 350.
Put 7 as the next digit of the answer. 
Result so far: 116347.0
Deduct 2730 from 3080 and we're left 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.

Moving on to step 9:
3500 divided by 390 is 8 with a remainder of 380.
Write down 8 as next digit of the result. 
Result so far: 116347.8
Subtracting 3120 from 3500 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.

On to step 10:
390 goes into 3800 9 times with a remainder of 290.
The next digit of our result is 9. 
Result so far: 116347.89
The remainder is 290 after subtracting 3510 from 3800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2900, and continue the process.

Advancing to step 11:
390 goes into 2900 7 times with a remainder of 170.
The number 7 becomes the next digit in our result. 
Result so far: 116347.897
Subtract 2730 from 2900 to 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.

Let's proceed to step 12:
1700 divided by 390 is 4 with a remainder of 140.
Record the quotient 4 as the next digit in the result. 
Result so far: 116347.8974
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.

Advancing to step 13:
The number 390 fits into 1400 3 times, leaving a remainder of 230.
The next digit of our result is 3. 
Result so far: 116347.89743
If we subtract 1170 from 1400, we 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.

Advancing to step 14:
390 can be fit into 2300 5 times, resulting in a remainder of 350.
Write down 5 as next digit of the result. 
Result so far: 116347.897435
Subtracting 1950 from 2300 leaves us 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.

Moving on to step 15:
When dividing 3500 by 390, we get 8 with a remainder of 380.
Write down 8 as next digit of the result. 
Result so far: 116347.8974358
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.

Advancing to step 16:
390 can be fit into 3800 9 times, resulting in a remainder of 290.
The number 9 becomes the next digit in our result. 
Result so far: 116347.89743589
The remainder is 290 after subtracting 3510 from 3800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2900, and continue the process.

Our division results in 116347.89743589 with a remaining 2.9e-07.
