We're dividing 86045454 by 344 
Our goal is to divide 86045454 by 344.

Moving on to step 1:
344 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.
Bring next digit (6) of the dividend behind the 8 and repeat the process: 86 / 344

On to step 2:
86 divided by 344 is 0 with a remainder of 86.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 86 and we're left with 86.
Fetch the next digit (0) from the dividend, attach it to 86 and continue: 860 / 344

Moving on to step 3:
If we divide 860 by 344, we get 2 and a remainder of 172.
The next digit of our result is 2. 
Result so far: 2.0
Subtract 688 from 860 to get 172.
Append the next digit (4) from the dividend to 172 and continue with: 1724 / 344

On to step 4:
If we divide 1724 by 344, we get 5 and a remainder of 4.
Record the quotient 5 as the next digit in the result. 
Result so far: 25.0
Deduct 1720 from 1724 and we're left with 4.
Grab the next digit (5) from the dividend, add it to 4, then carry on: 45 / 344

Let's proceed to step 5:
45 divided by 344 is 0 with a remainder of 45.
The number 0 becomes the next digit in our result. 
Result so far: 250.0
If we take 0 away from 45, we end up with 45.
Include the next digit (4) from the dividend after 45, then repeat: 454 / 344

Moving on to step 6:
When dividing 454 by 344, we get 1 with a remainder of 110.
Record the quotient 1 as the next digit in the result. 
Result so far: 2501.0
If we take 344 away from 454, we end up with 110.
Include the next digit (5) from the dividend after 110, then repeat: 1105 / 344

Going ahead to step 7:
344 can be fit into 1105 3 times, resulting in a remainder of 73.
Record the quotient 3 as the next digit in the result. 
Result so far: 25013.0
If we subtract 1032 from 1105, we get 73.
Take the next digit (4) from the dividend and append it to 73, then repeat: 734 / 344

On to step 8:
If we divide 734 by 344, we get 2 and a remainder of 46.
Record the quotient 2 as the next digit in the result. 
Result so far: 250132.0
Subtracting 688 from 734 leaves us with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Going ahead to step 9:
If we divide 460 by 344, we get 1 and a remainder of 116.
Record the quotient 1 as the next digit in the result. 
Result so far: 250132.1
The remainder is 116 after subtracting 344 from 460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1160, and continue the process.

Going ahead to step 10:
344 can be fit into 1160 3 times, resulting in a remainder of 128.
Write down 3 as next digit of the result. 
Result so far: 250132.13
Deduct 1032 from 1160 and we're left with 128.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1280, and continue the process.

Moving on to step 11:
When dividing 1280 by 344, we get 3 with a remainder of 248.
Record the quotient 3 as the next digit in the result. 
Result so far: 250132.133
Subtract 1032 from 1280 to get 248.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2480, and continue the process.

The final outcome is 250132.133, with a leftover of 0.0248.
