We divide 158579 by 45
Our goal is to divide 158579 by 45.

Advancing to step 1:
When dividing 1 by 45, we get 0 with a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Grab the next digit (5) from the dividend, add it to 1, then carry on: 15 / 45

Advancing to step 2:
The number 45 fits into 15 0 times, leaving a remainder of 15.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 15 and we're left with 15.
Grab the next digit (8) from the dividend, add it to 15, then carry on: 158 / 45

Step 3:
If we divide 158 by 45, we get 3 and a remainder of 23.
Put 3 as the next digit of the answer. 
Result so far: 3.0
Subtract 135 from 158 to get 23.
Include the next digit (5) from the dividend after 23, then repeat: 235 / 45

Going ahead to step 4:
The number 45 fits into 235 5 times, leaving a remainder of 10.
The next digit of our result is 5. 
Result so far: 35.0
If we subtract 225 from 235, we get 10.
Append the next digit (7) from the dividend to 10 and continue with: 107 / 45

Moving on to step 5:
45 goes into 107 2 times with a remainder of 17.
Use 2 as the next digit of our solution. 
Result so far: 352.0
Subtracting 90 from 107 leaves us with 17.
Bring next digit (9) of the dividend behind the 17 and repeat the process: 179 / 45

Step 6:
45 can be fit into 179 3 times, resulting in a remainder of 44.
The number 3 becomes the next digit in our result. 
Result so far: 3523.0
The remainder is 44 after subtracting 135 from 179.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Moving on to step 7:
45 can be fit into 440 9 times, resulting in a remainder of 35.
Put 9 as the next digit of the answer. 
Result so far: 3523.9
Subtract 405 from 440 to get 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Moving on to step 8:
When dividing 350 by 45, we get 7 with a remainder of 35.
Put 7 as the next digit of the answer. 
Result so far: 3523.97
If we take 315 away from 350, we end up with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Step 9:
If we divide 350 by 45, we get 7 and a remainder of 35.
Use 7 as the next digit of our solution. 
Result so far: 3523.977
If we take 315 away from 350, we end up with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

The final outcome is 3523.977, with a leftover of 0.0035.
