85167790 ÷ 158 
Our goal is to divide 85167790 by 158.

Let's proceed to step 1:
158 can be fit into 8 0 times, resulting in a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Append the next digit (5) from the dividend to 8 and continue with: 85 / 158

Advancing to step 2:
158 can be fit into 85 0 times, resulting in a remainder of 85.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 85 after subtracting 0 from 85.
Include the next digit (1) from the dividend after 85, then repeat: 851 / 158

On to step 3:
158 can be fit into 851 5 times, resulting in a remainder of 61.
The next digit of our result is 5. 
Result so far: 5.0
If we subtract 790 from 851, we get 61.
Take the next digit (6) from the dividend and append it to 61, then repeat: 616 / 158

On to step 4:
616 divided by 158 is 3 with a remainder of 142.
Put 3 as the next digit of the answer. 
Result so far: 53.0
Subtracting 474 from 616 leaves us with 142.
Take the next digit (7) from the dividend and append it to 142, then repeat: 1427 / 158

Advancing to step 5:
The number 158 fits into 1427 9 times, leaving a remainder of 5.
Use 9 as the next digit of our solution. 
Result so far: 539.0
Subtracting 1422 from 1427 leaves us with 5.
Take the next digit (7) from the dividend and append it to 5, then repeat: 57 / 158

Going ahead to step 6:
If we divide 57 by 158, we get 0 and a remainder of 57.
Use 0 as the next digit of our solution. 
Result so far: 5390.0
Subtracting 0 from 57 leaves us with 57.
Grab the next digit (9) from the dividend, add it to 57, then carry on: 579 / 158

Moving on to step 7:
When dividing 579 by 158, we get 3 with a remainder of 105.
The number 3 becomes the next digit in our result. 
Result so far: 53903.0
Deduct 474 from 579 and we're left with 105.
Include the next digit (0) from the dividend after 105, then repeat: 1050 / 158

Step 8:
If we divide 1050 by 158, we get 6 and a remainder of 102.
The number 6 becomes the next digit in our result. 
Result so far: 539036.0
Subtracting 948 from 1050 leaves us with 102.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1020, and continue the process.

Let's proceed to step 9:
The number 158 fits into 1020 6 times, leaving a remainder of 72.
Record the quotient 6 as the next digit in the result. 
Result so far: 539036.6
Deduct 948 from 1020 and we're left with 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

On to step 10:
720 divided by 158 is 4 with a remainder of 88.
The next digit of our result is 4. 
Result so far: 539036.64
Subtracting 632 from 720 leaves us with 88.
Since there are no more digits in the dividend, we add a zero to the remainder making it 880, and continue the process.

Moving on to step 11:
158 can be fit into 880 5 times, resulting in a remainder of 90.
Write down 5 as next digit of the result. 
Result so far: 539036.645
Subtracting 790 from 880 leaves us with 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

Step 12:
158 goes into 900 5 times with a remainder of 110.
The number 5 becomes the next digit in our result. 
Result so far: 539036.6455
Subtract 790 from 900 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.

In conclusion, the division gives 539036.6455 with a balance of 0.0011.
