81129485 ÷ 236 
We want to divide 81129485 by 236.

Going ahead to step 1:
When dividing 8 by 236, we get 0 with a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Include the next digit (1) from the dividend after 8, then repeat: 81 / 236

Advancing to step 2:
When dividing 81 by 236, we get 0 with a remainder of 81.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 81 to get 81.
Bring next digit (1) of the dividend behind the 81 and repeat the process: 811 / 236

Let's proceed to step 3:
236 goes into 811 3 times with a remainder of 103.
Put 3 as the next digit of the answer. 
Result so far: 3.0
Deduct 708 from 811 and we're left with 103.
Take the next digit (2) from the dividend and append it to 103, then repeat: 1032 / 236

Advancing to step 4:
If we divide 1032 by 236, we get 4 and a remainder of 88.
The next digit of our result is 4. 
Result so far: 34.0
If we subtract 944 from 1032, we get 88.
Include the next digit (9) from the dividend after 88, then repeat: 889 / 236

Let's proceed to step 5:
889 divided by 236 is 3 with a remainder of 181.
Record the quotient 3 as the next digit in the result. 
Result so far: 343.0
Deduct 708 from 889 and we're left with 181.
Append the next digit (4) from the dividend to 181 and continue with: 1814 / 236

Step 6:
The number 236 fits into 1814 7 times, leaving a remainder of 162.
Put 7 as the next digit of the answer. 
Result so far: 3437.0
Deduct 1652 from 1814 and we're left with 162.
Append the next digit (8) from the dividend to 162 and continue with: 1628 / 236

Going ahead to step 7:
The number 236 fits into 1628 6 times, leaving a remainder of 212.
The number 6 becomes the next digit in our result. 
Result so far: 34376.0
If we subtract 1416 from 1628, we get 212.
Bring next digit (5) of the dividend behind the 212 and repeat the process: 2125 / 236

On to step 8:
The number 236 fits into 2125 9 times, leaving a remainder of 1.
Record the quotient 9 as the next digit in the result. 
Result so far: 343769.0
Subtracting 2124 from 2125 leaves us with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Let's proceed to step 9:
When dividing 10 by 236, we get 0 with a remainder of 10.
Write down 0 as next digit of the result. 
Result so far: 343769.0
The remainder is 10 after subtracting 0 from 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Let's proceed to step 10:
If we divide 100 by 236, we get 0 and a remainder of 100.
Record the quotient 0 as the next digit in the result. 
Result so far: 343769.0
If we take 0 away from 100, we end up with 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

In conclusion, the division gives 343769.0 with a balance of 0.1.
