We look at the division of 78393011 by 422 
We're looking to find how many times 422 goes into 78393011.

Moving on to step 1:
When dividing 7 by 422, we get 0 with a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Include the next digit (8) from the dividend after 7, then repeat: 78 / 422

Advancing to step 2:
78 divided by 422 is 0 with a remainder of 78.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 78 leaves us with 78.
Fetch the next digit (3) from the dividend, attach it to 78 and continue: 783 / 422

On to step 3:
422 can be fit into 783 1 times, resulting in a remainder of 361.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtract 422 from 783 to get 361.
Append the next digit (9) from the dividend to 361 and continue with: 3619 / 422

Moving on to step 4:
If we divide 3619 by 422, we get 8 and a remainder of 243.
Record the quotient 8 as the next digit in the result. 
Result so far: 18.0
The remainder is 243 after subtracting 3376 from 3619.
Bring next digit (3) of the dividend behind the 243 and repeat the process: 2433 / 422

On to step 5:
When dividing 2433 by 422, we get 5 with a remainder of 323.
The next digit of our result is 5. 
Result so far: 185.0
If we take 2110 away from 2433, we end up with 323.
Fetch the next digit (0) from the dividend, attach it to 323 and continue: 3230 / 422

Step 6:
If we divide 3230 by 422, we get 7 and a remainder of 276.
The number 7 becomes the next digit in our result. 
Result so far: 1857.0
Deduct 2954 from 3230 and we're left with 276.
Grab the next digit (1) from the dividend, add it to 276, then carry on: 2761 / 422

Step 7:
2761 divided by 422 is 6 with a remainder of 229.
Use 6 as the next digit of our solution. 
Result so far: 18576.0
If we subtract 2532 from 2761, we get 229.
Grab the next digit (1) from the dividend, add it to 229, then carry on: 2291 / 422

Advancing to step 8:
The number 422 fits into 2291 5 times, leaving a remainder of 181.
Record the quotient 5 as the next digit in the result. 
Result so far: 185765.0
Deduct 2110 from 2291 and we're left with 181.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1810, and continue the process.

Going ahead to step 9:
1810 divided by 422 is 4 with a remainder of 122.
The number 4 becomes the next digit in our result. 
Result so far: 185765.4
Subtracting 1688 from 1810 leaves us with 122.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1220, and continue the process.

Going ahead to step 10:
The number 422 fits into 1220 2 times, leaving a remainder of 376.
Use 2 as the next digit of our solution. 
Result so far: 185765.42
Deduct 844 from 1220 and we're left with 376.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3760, and continue the process.

Step 11:
When dividing 3760 by 422, we get 8 with a remainder of 384.
The next digit of our result is 8. 
Result so far: 185765.428
The remainder is 384 after subtracting 3376 from 3760.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3840, and continue the process.

Advancing to step 12:
3840 divided by 422 is 9 with a remainder of 42.
The next digit of our result is 9. 
Result so far: 185765.4289
The remainder is 42 after subtracting 3798 from 3840.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Going ahead to step 13:
420 divided by 422 is 0 with a remainder of 420.
Put 0 as the next digit of the answer. 
Result so far: 185765.4289
Subtract 0 from 420 to get 420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4200, and continue the process.

Going ahead to step 14:
When dividing 4200 by 422, we get 9 with a remainder of 402.
Write down 9 as next digit of the result. 
Result so far: 185765.428909
If we take 3798 away from 4200, we end up with 402.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4020, and continue the process.

Going ahead to step 15:
422 can be fit into 4020 9 times, resulting in a remainder of 222.
Use 9 as the next digit of our solution. 
Result so far: 185765.4289099
If we subtract 3798 from 4020, we get 222.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2220, and continue the process.

After the division, we end up with 185765.4289099 and a remainder of 2.22e-06.
