Let's divide 78155894 by 178
Our goal is to divide 78155894 by 178.

Going ahead to step 1:
If we divide 7 by 178, we get 0 and a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Append the next digit (8) from the dividend to 7 and continue with: 78 / 178

Advancing to step 2:
178 can be fit into 78 0 times, resulting in a remainder of 78.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 78 to get 78.
Grab the next digit (1) from the dividend, add it to 78, then carry on: 781 / 178

Going ahead to step 3:
When dividing 781 by 178, we get 4 with a remainder of 69.
The next digit of our result is 4. 
Result so far: 4.0
Deduct 712 from 781 and we're left with 69.
Include the next digit (5) from the dividend after 69, then repeat: 695 / 178

Step 4:
178 goes into 695 3 times with a remainder of 161.
The number 3 becomes the next digit in our result. 
Result so far: 43.0
Subtract 534 from 695 to get 161.
Grab the next digit (5) from the dividend, add it to 161, then carry on: 1615 / 178

Advancing to step 5:
When dividing 1615 by 178, we get 9 with a remainder of 13.
Put 9 as the next digit of the answer. 
Result so far: 439.0
Deduct 1602 from 1615 and we're left with 13.
Take the next digit (8) from the dividend and append it to 13, then repeat: 138 / 178

Advancing to step 6:
When dividing 138 by 178, we get 0 with a remainder of 138.
Use 0 as the next digit of our solution. 
Result so far: 4390.0
If we subtract 0 from 138, we get 138.
Take the next digit (9) from the dividend and append it to 138, then repeat: 1389 / 178

Step 7:
If we divide 1389 by 178, we get 7 and a remainder of 143.
The number 7 becomes the next digit in our result. 
Result so far: 43907.0
Subtract 1246 from 1389 to get 143.
Append the next digit (4) from the dividend to 143 and continue with: 1434 / 178

Step 8:
When dividing 1434 by 178, we get 8 with a remainder of 10.
Use 8 as the next digit of our solution. 
Result so far: 439078.0
The remainder is 10 after subtracting 1424 from 1434.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 9:
100 divided by 178 is 0 with a remainder of 100.
Write down 0 as next digit of the result. 
Result so far: 439078.0
The remainder is 100 after subtracting 0 from 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 10:
The number 178 fits into 1000 5 times, leaving a remainder of 110.
Put 5 as the next digit of the answer. 
Result so far: 439078.05
Subtract 890 from 1000 to get 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1100, and continue the process.

Let's proceed to step 11:
If we divide 1100 by 178, we get 6 and a remainder of 32.
Record the quotient 6 as the next digit in the result. 
Result so far: 439078.056
If we subtract 1068 from 1100, we get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Let's proceed to step 12:
The number 178 fits into 320 1 times, leaving a remainder of 142.
Use 1 as the next digit of our solution. 
Result so far: 439078.0561
Subtracting 178 from 320 leaves us with 142.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1420, and continue the process.

Step 13:
If we divide 1420 by 178, we get 7 and a remainder of 174.
Write down 7 as next digit of the result. 
Result so far: 439078.05617
If we take 1246 away from 1420, we end up with 174.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1740, and continue the process.

Moving on to step 14:
1740 divided by 178 is 9 with a remainder of 138.
Put 9 as the next digit of the answer. 
Result so far: 439078.056179
Subtracting 1602 from 1740 leaves us with 138.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1380, and continue the process.

Let's proceed to step 15:
When dividing 1380 by 178, we get 7 with a remainder of 134.
Put 7 as the next digit of the answer. 
Result so far: 439078.0561797
If we subtract 1246 from 1380, we get 134.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1340, and continue the process.

Going ahead to step 16:
178 can be fit into 1340 7 times, resulting in a remainder of 94.
Record the quotient 7 as the next digit in the result. 
Result so far: 439078.05617977
If we subtract 1246 from 1340, we get 94.
Since there are no more digits in the dividend, we add a zero to the remainder making it 940, and continue the process.

The final result is 439078.05617977 with a remainder of 9.4e-08.
