We're dividing 19355245 by 78 
We want to figure out the number of times 19355245 can be divided by 78.

Advancing to step 1:
78 goes into 1 0 times with a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Append the next digit (9) from the dividend to 1 and continue with: 19 / 78

Advancing to step 2:
19 divided by 78 is 0 with a remainder of 19.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 19, we end up with 19.
Take the next digit (3) from the dividend and append it to 19, then repeat: 193 / 78

Advancing to step 3:
The number 78 fits into 193 2 times, leaving a remainder of 37.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
If we take 156 away from 193, we end up with 37.
Grab the next digit (5) from the dividend, add it to 37, then carry on: 375 / 78

Let's proceed to step 4:
If we divide 375 by 78, we get 4 and a remainder of 63.
The next digit of our result is 4. 
Result so far: 24.0
The remainder is 63 after subtracting 312 from 375.
Fetch the next digit (5) from the dividend, attach it to 63 and continue: 635 / 78

Let's proceed to step 5:
The number 78 fits into 635 8 times, leaving a remainder of 11.
Put 8 as the next digit of the answer. 
Result so far: 248.0
If we take 624 away from 635, we end up with 11.
Append the next digit (2) from the dividend to 11 and continue with: 112 / 78

Advancing to step 6:
78 goes into 112 1 times with a remainder of 34.
The next digit of our result is 1. 
Result so far: 2481.0
If we take 78 away from 112, we end up with 34.
Append the next digit (4) from the dividend to 34 and continue with: 344 / 78

Going ahead to step 7:
344 divided by 78 is 4 with a remainder of 32.
Record the quotient 4 as the next digit in the result. 
Result so far: 24814.0
The remainder is 32 after subtracting 312 from 344.
Bring next digit (5) of the dividend behind the 32 and repeat the process: 325 / 78

Going ahead to step 8:
78 goes into 325 4 times with a remainder of 13.
Use 4 as the next digit of our solution. 
Result so far: 248144.0
Deduct 312 from 325 and we're left with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Step 9:
78 goes into 130 1 times with a remainder of 52.
Write down 1 as next digit of the result. 
Result so far: 248144.1
Deduct 78 from 130 and we're left with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Step 10:
78 can be fit into 520 6 times, resulting in a remainder of 52.
The number 6 becomes the next digit in our result. 
Result so far: 248144.16
Deduct 468 from 520 and we're left with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Step 11:
When dividing 520 by 78, we get 6 with a remainder of 52.
Record the quotient 6 as the next digit in the result. 
Result so far: 248144.166
If we take 468 away from 520, we end up with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

In conclusion, the division gives 248144.166 with a balance of 0.0052.
