We're dividing 81145691 by 178 
Our goal is to divide 81145691 by 178.

On to step 1:
When dividing 8 by 178, we get 0 with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Append the next digit (1) from the dividend to 8 and continue with: 81 / 178

Moving on to step 2:
When dividing 81 by 178, we get 0 with a remainder of 81.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 81 after subtracting 0 from 81.
Grab the next digit (1) from the dividend, add it to 81, then carry on: 811 / 178

Advancing to step 3:
178 can be fit into 811 4 times, resulting in a remainder of 99.
Put 4 as the next digit of the answer. 
Result so far: 4.0
The remainder is 99 after subtracting 712 from 811.
Take the next digit (4) from the dividend and append it to 99, then repeat: 994 / 178

Step 4:
When dividing 994 by 178, we get 5 with a remainder of 104.
Put 5 as the next digit of the answer. 
Result so far: 45.0
Subtracting 890 from 994 leaves us with 104.
Take the next digit (5) from the dividend and append it to 104, then repeat: 1045 / 178

Advancing to step 5:
1045 divided by 178 is 5 with a remainder of 155.
Write down 5 as next digit of the result. 
Result so far: 455.0
Subtract 890 from 1045 to get 155.
Fetch the next digit (6) from the dividend, attach it to 155 and continue: 1556 / 178

Moving on to step 6:
If we divide 1556 by 178, we get 8 and a remainder of 132.
The number 8 becomes the next digit in our result. 
Result so far: 4558.0
Subtract 1424 from 1556 to get 132.
Fetch the next digit (9) from the dividend, attach it to 132 and continue: 1329 / 178

Let's proceed to step 7:
The number 178 fits into 1329 7 times, leaving a remainder of 83.
The next digit of our result is 7. 
Result so far: 45587.0
Deduct 1246 from 1329 and we're left with 83.
Bring next digit (1) of the dividend behind the 83 and repeat the process: 831 / 178

Moving on to step 8:
831 divided by 178 is 4 with a remainder of 119.
Record the quotient 4 as the next digit in the result. 
Result so far: 455874.0
Subtracting 712 from 831 leaves us with 119.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1190, and continue the process.

On to step 9:
If we divide 1190 by 178, we get 6 and a remainder of 122.
The number 6 becomes the next digit in our result. 
Result so far: 455874.6
Subtract 1068 from 1190 to get 122.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1220, and continue the process.

Let's proceed to step 10:
178 goes into 1220 6 times with a remainder of 152.
The number 6 becomes the next digit in our result. 
Result so far: 455874.66
Subtracting 1068 from 1220 leaves us with 152.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1520, and continue the process.

The final outcome is 455874.66, with a leftover of 0.152.
