We look at the division of 81069754 by 158 
We want to figure out the number of times 81069754 can be divided by 158.

On to step 1:
158 can be fit into 8 0 times, resulting in a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Fetch the next digit (1) from the dividend, attach it to 8 and continue: 81 / 158

Let's proceed to step 2:
158 goes into 81 0 times with a remainder of 81.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 81 to get 81.
Bring next digit (0) of the dividend behind the 81 and repeat the process: 810 / 158

Let's proceed to step 3:
When dividing 810 by 158, we get 5 with a remainder of 20.
Record the quotient 5 as the next digit in the result. 
Result so far: 5.0
If we subtract 790 from 810, we get 20.
Append the next digit (6) from the dividend to 20 and continue with: 206 / 158

On to step 4:
If we divide 206 by 158, we get 1 and a remainder of 48.
The next digit of our result is 1. 
Result so far: 51.0
If we subtract 158 from 206, we get 48.
Grab the next digit (9) from the dividend, add it to 48, then carry on: 489 / 158

Step 5:
If we divide 489 by 158, we get 3 and a remainder of 15.
Use 3 as the next digit of our solution. 
Result so far: 513.0
Deduct 474 from 489 and we're left with 15.
Grab the next digit (7) from the dividend, add it to 15, then carry on: 157 / 158

Let's proceed to step 6:
When dividing 157 by 158, we get 0 with a remainder of 157.
Write down 0 as next digit of the result. 
Result so far: 5130.0
Subtract 0 from 157 to get 157.
Append the next digit (5) from the dividend to 157 and continue with: 1575 / 158

Moving on to step 7:
When dividing 1575 by 158, we get 9 with a remainder of 153.
Use 9 as the next digit of our solution. 
Result so far: 51309.0
Subtract 1422 from 1575 to get 153.
Include the next digit (4) from the dividend after 153, then repeat: 1534 / 158

Let's proceed to step 8:
When dividing 1534 by 158, we get 9 with a remainder of 112.
Record the quotient 9 as the next digit in the result. 
Result so far: 513099.0
Subtract 1422 from 1534 to get 112.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1120, and continue the process.

Going ahead to step 9:
When dividing 1120 by 158, we get 7 with a remainder of 14.
The next digit of our result is 7. 
Result so far: 513099.7
Subtracting 1106 from 1120 leaves us with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Advancing to step 10:
158 can be fit into 140 0 times, resulting in a remainder of 140.
Put 0 as the next digit of the answer. 
Result so far: 513099.7
If we take 0 away from 140, we end up with 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

Going ahead to step 11:
The number 158 fits into 1400 8 times, leaving a remainder of 136.
Record the quotient 8 as the next digit in the result. 
Result so far: 513099.708
Subtracting 1264 from 1400 leaves us with 136.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1360, and continue the process.

Advancing to step 12:
If we divide 1360 by 158, we get 8 and a remainder of 96.
Write down 8 as next digit of the result. 
Result so far: 513099.7088
Subtract 1264 from 1360 to get 96.
Since there are no more digits in the dividend, we add a zero to the remainder making it 960, and continue the process.

The final result is 513099.7088 with a remainder of 0.00096.
