Let's divide 193551 by 78
We're looking to find how many times 78 goes into 193551.

Step 1:
If we divide 1 by 78, we get 0 and a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Append the next digit (9) from the dividend to 1 and continue with: 19 / 78

Going ahead to step 2:
19 divided by 78 is 0 with a remainder of 19.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 19 and we're left with 19.
Take the next digit (3) from the dividend and append it to 19, then repeat: 193 / 78

Advancing to step 3:
If we divide 193 by 78, we get 2 and a remainder of 37.
Put 2 as the next digit of the answer. 
Result so far: 2.0
If we subtract 156 from 193, we get 37.
Append the next digit (5) from the dividend to 37 and continue with: 375 / 78

On to step 4:
78 goes into 375 4 times with a remainder of 63.
The number 4 becomes the next digit in our result. 
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

Advancing to step 5:
78 can be fit into 635 8 times, resulting in a remainder of 11.
The number 8 becomes the next digit in our result. 
Result so far: 248.0
The remainder is 11 after subtracting 624 from 635.
Fetch the next digit (1) from the dividend, attach it to 11 and continue: 111 / 78

Moving on to step 6:
The number 78 fits into 111 1 times, leaving a remainder of 33.
Record the quotient 1 as the next digit in the result. 
Result so far: 2481.0
If we subtract 78 from 111, we get 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Step 7:
The number 78 fits into 330 4 times, leaving a remainder of 18.
Put 4 as the next digit of the answer. 
Result so far: 2481.4
Subtracting 312 from 330 leaves us with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Let's proceed to step 8:
The number 78 fits into 180 2 times, leaving a remainder of 24.
Put 2 as the next digit of the answer. 
Result so far: 2481.42
Deduct 156 from 180 and we're left with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Let's proceed to step 9:
78 goes into 240 3 times with a remainder of 6.
Record the quotient 3 as the next digit in the result. 
Result so far: 2481.423
Subtract 234 from 240 to get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Advancing to step 10:
If we divide 60 by 78, we get 0 and a remainder of 60.
Put 0 as the next digit of the answer. 
Result so far: 2481.423
Subtracting 0 from 60 leaves us 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.

Moving on to step 11:
The number 78 fits into 600 7 times, leaving a remainder of 54.
Write down 7 as next digit of the result. 
Result so far: 2481.42307
If we subtract 546 from 600, we get 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Advancing to step 12:
The number 78 fits into 540 6 times, leaving a remainder of 72.
Put 6 as the next digit of the answer. 
Result so far: 2481.423076
Subtract 468 from 540 to get 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Moving on to step 13:
The number 78 fits into 720 9 times, leaving a remainder of 18.
Write down 9 as next digit of the result. 
Result so far: 2481.4230769
If we take 702 away from 720, we end up with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Let's proceed to step 14:
The number 78 fits into 180 2 times, leaving a remainder of 24.
Put 2 as the next digit of the answer. 
Result so far: 2481.42307692
If we take 156 away from 180, we end up with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Our division results in 2481.42307692 with a remaining 2.4e-08.
