Let's divide 78120130 by 410
We're looking to find how many times 410 goes into 78120130.

Step 1:
410 goes into 7 0 times with a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Fetch the next digit (8) from the dividend, attach it to 7 and continue: 78 / 410

On to step 2:
The number 410 fits into 78 0 times, leaving a remainder of 78.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 78, we end up with 78.
Append the next digit (1) from the dividend to 78 and continue with: 781 / 410

Step 3:
410 can be fit into 781 1 times, resulting in a remainder of 371.
Write down 1 as next digit of the result. 
Result so far: 1.0
Deduct 410 from 781 and we're left with 371.
Fetch the next digit (2) from the dividend, attach it to 371 and continue: 3712 / 410

On to step 4:
If we divide 3712 by 410, we get 9 and a remainder of 22.
The next digit of our result is 9. 
Result so far: 19.0
Subtracting 3690 from 3712 leaves us with 22.
Bring next digit (0) of the dividend behind the 22 and repeat the process: 220 / 410

Advancing to step 5:
The number 410 fits into 220 0 times, leaving a remainder of 220.
Use 0 as the next digit of our solution. 
Result so far: 190.0
If we subtract 0 from 220, we get 220.
Take the next digit (1) from the dividend and append it to 220, then repeat: 2201 / 410

Step 6:
The number 410 fits into 2201 5 times, leaving a remainder of 151.
Put 5 as the next digit of the answer. 
Result so far: 1905.0
If we subtract 2050 from 2201, we get 151.
Grab the next digit (3) from the dividend, add it to 151, then carry on: 1513 / 410

Let's proceed to step 7:
410 goes into 1513 3 times with a remainder of 283.
The next digit of our result is 3. 
Result so far: 19053.0
The remainder is 283 after subtracting 1230 from 1513.
Include the next digit (0) from the dividend after 283, then repeat: 2830 / 410

Going ahead to step 8:
When dividing 2830 by 410, we get 6 with a remainder of 370.
Put 6 as the next digit of the answer. 
Result so far: 190536.0
Subtract 2460 from 2830 to get 370.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3700, and continue the process.

Going ahead to step 9:
410 goes into 3700 9 times with a remainder of 10.
Record the quotient 9 as the next digit in the result. 
Result so far: 190536.9
Subtract 3690 from 3700 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 10:
100 divided by 410 is 0 with a remainder of 100.
Put 0 as the next digit of the answer. 
Result so far: 190536.9
Subtract 0 from 100 to get 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Moving on to step 11:
The number 410 fits into 1000 2 times, leaving a remainder of 180.
The next digit of our result is 2. 
Result so far: 190536.902
Deduct 820 from 1000 and we're left with 180.
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 12:
The number 410 fits into 1800 4 times, leaving a remainder of 160.
Record the quotient 4 as the next digit in the result. 
Result so far: 190536.9024
If we take 1640 away from 1800, we end up with 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Advancing to step 13:
If we divide 1600 by 410, we get 3 and a remainder of 370.
The next digit of our result is 3. 
Result so far: 190536.90243
Subtract 1230 from 1600 to get 370.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3700, and continue the process.

On to step 14:
When dividing 3700 by 410, we get 9 with a remainder of 10.
The number 9 becomes the next digit in our result. 
Result so far: 190536.902439
Subtracting 3690 from 3700 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 15:
100 divided by 410 is 0 with a remainder of 100.
Record the quotient 0 as the next digit in the result. 
Result so far: 190536.902439
Subtracting 0 from 100 leaves us with 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Going ahead to step 16:
1000 divided by 410 is 2 with a remainder of 180.
Put 2 as the next digit of the answer. 
Result so far: 190536.90243902
If we take 820 away from 1000, we end up with 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 outcome is 190536.90243902, with a leftover of 1.8e-07.
