We're dividing 71172459 by 390 
Let's see how many times 390 fits into 71172459.

Let's proceed to step 1:
When dividing 7 by 390, we get 0 with a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Take the next digit (1) from the dividend and append it to 7, then repeat: 71 / 390

On to step 2:
390 goes into 71 0 times with a remainder of 71.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 71 and we're left with 71.
Grab the next digit (1) from the dividend, add it to 71, then carry on: 711 / 390

Advancing to step 3:
When dividing 711 by 390, we get 1 with a remainder of 321.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtracting 390 from 711 leaves us with 321.
Take the next digit (7) from the dividend and append it to 321, then repeat: 3217 / 390

Moving on to step 4:
390 can be fit into 3217 8 times, resulting in a remainder of 97.
Put 8 as the next digit of the answer. 
Result so far: 18.0
Subtracting 3120 from 3217 leaves us with 97.
Fetch the next digit (2) from the dividend, attach it to 97 and continue: 972 / 390

Advancing to step 5:
The number 390 fits into 972 2 times, leaving a remainder of 192.
Put 2 as the next digit of the answer. 
Result so far: 182.0
If we subtract 780 from 972, we get 192.
Bring next digit (4) of the dividend behind the 192 and repeat the process: 1924 / 390

On to step 6:
When dividing 1924 by 390, we get 4 with a remainder of 364.
The number 4 becomes the next digit in our result. 
Result so far: 1824.0
Deduct 1560 from 1924 and we're left with 364.
Fetch the next digit (5) from the dividend, attach it to 364 and continue: 3645 / 390

Advancing to step 7:
3645 divided by 390 is 9 with a remainder of 135.
Put 9 as the next digit of the answer. 
Result so far: 18249.0
Deduct 3510 from 3645 and we're left with 135.
Bring next digit (9) of the dividend behind the 135 and repeat the process: 1359 / 390

Going ahead to step 8:
1359 divided by 390 is 3 with a remainder of 189.
Put 3 as the next digit of the answer. 
Result so far: 182493.0
Subtract 1170 from 1359 to get 189.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1890, and continue the process.

Advancing to step 9:
The number 390 fits into 1890 4 times, leaving a remainder of 330.
Put 4 as the next digit of the answer. 
Result so far: 182493.4
Subtract 1560 from 1890 to get 330.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3300, and continue the process.

Let's proceed to step 10:
390 can be fit into 3300 8 times, resulting in a remainder of 180.
The number 8 becomes the next digit in our result. 
Result so far: 182493.48
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.

On to step 11:
If we divide 1800 by 390, we get 4 and a remainder of 240.
Put 4 as the next digit of the answer. 
Result so far: 182493.484
If we subtract 1560 from 1800, we get 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

Let's proceed to step 12:
If we divide 2400 by 390, we get 6 and a remainder of 60.
The next digit of our result is 6. 
Result so far: 182493.4846
If we take 2340 away from 2400, we end up 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.

Step 13:
If we divide 600 by 390, we get 1 and a remainder of 210.
Put 1 as the next digit of the answer. 
Result so far: 182493.48461
If we subtract 390 from 600, we get 210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2100, and continue the process.

Advancing to step 14:
When dividing 2100 by 390, we get 5 with a remainder of 150.
Write down 5 as next digit of the result. 
Result so far: 182493.484615
Subtract 1950 from 2100 to get 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

Let's proceed to step 15:
If we divide 1500 by 390, we get 3 and a remainder of 330.
Put 3 as the next digit of the answer. 
Result so far: 182493.4846153
If we subtract 1170 from 1500, we get 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 16:
The number 390 fits into 3300 8 times, leaving a remainder of 180.
The number 8 becomes the next digit in our result. 
Result so far: 182493.48461538
If we subtract 3120 from 3300, we 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.

The final result is 182493.48461538 with a remainder of 1.8e-07.
