We're dividing 78923580 by 158 
Our goal is to divide 78923580 by 158.

Let's proceed to step 1:
The number 158 fits into 7 0 times, leaving a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Grab the next digit (8) from the dividend, add it to 7, then carry on: 78 / 158

Let's proceed to step 2:
If we divide 78 by 158, we get 0 and a remainder of 78.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 78, we get 78.
Take the next digit (9) from the dividend and append it to 78, then repeat: 789 / 158

Let's proceed to step 3:
If we divide 789 by 158, we get 4 and a remainder of 157.
Write down 4 as next digit of the result. 
Result so far: 4.0
Deduct 632 from 789 and we're left with 157.
Grab the next digit (2) from the dividend, add it to 157, then carry on: 1572 / 158

Step 4:
When dividing 1572 by 158, we get 9 with a remainder of 150.
Use 9 as the next digit of our solution. 
Result so far: 49.0
If we subtract 1422 from 1572, we get 150.
Fetch the next digit (3) from the dividend, attach it to 150 and continue: 1503 / 158

Advancing to step 5:
1503 divided by 158 is 9 with a remainder of 81.
The number 9 becomes the next digit in our result. 
Result so far: 499.0
If we take 1422 away from 1503, we end up with 81.
Bring next digit (5) of the dividend behind the 81 and repeat the process: 815 / 158

Step 6:
The number 158 fits into 815 5 times, leaving a remainder of 25.
Record the quotient 5 as the next digit in the result. 
Result so far: 4995.0
Subtracting 790 from 815 leaves us with 25.
Fetch the next digit (8) from the dividend, attach it to 25 and continue: 258 / 158

Moving on to step 7:
158 can be fit into 258 1 times, resulting in a remainder of 100.
Put 1 as the next digit of the answer. 
Result so far: 49951.0
If we subtract 158 from 258, we get 100.
Fetch the next digit (0) from the dividend, attach it to 100 and continue: 1000 / 158

Going ahead to step 8:
1000 divided by 158 is 6 with a remainder of 52.
Put 6 as the next digit of the answer. 
Result so far: 499516.0
If we take 948 away from 1000, 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.

Advancing to step 9:
158 goes into 520 3 times with a remainder of 46.
Put 3 as the next digit of the answer. 
Result so far: 499516.3
Subtracting 474 from 520 leaves us with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Step 10:
460 divided by 158 is 2 with a remainder of 144.
The next digit of our result is 2. 
Result so far: 499516.32
Deduct 316 from 460 and we're left with 144.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1440, and continue the process.

Let's proceed to step 11:
158 goes into 1440 9 times with a remainder of 18.
The number 9 becomes the next digit in our result. 
Result so far: 499516.329
Subtracting 1422 from 1440 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 12:
180 divided by 158 is 1 with a remainder of 22.
Put 1 as the next digit of the answer. 
Result so far: 499516.3291
Subtract 158 from 180 to get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Advancing to step 13:
When dividing 220 by 158, we get 1 with a remainder of 62.
Use 1 as the next digit of our solution. 
Result so far: 499516.32911
The remainder is 62 after subtracting 158 from 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

The final result is 499516.32911 with a remainder of 6.2e-05.
