We look at the division of 86539396 by 148 
Let's see how many times 148 fits into 86539396.

On to step 1:
148 goes into 8 0 times with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Include the next digit (6) from the dividend after 8, then repeat: 86 / 148

Moving on to step 2:
If we divide 86 by 148, we get 0 and a remainder of 86.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 86, we get 86.
Fetch the next digit (5) from the dividend, attach it to 86 and continue: 865 / 148

Let's proceed to step 3:
148 can be fit into 865 5 times, resulting in a remainder of 125.
Use 5 as the next digit of our solution. 
Result so far: 5.0
If we subtract 740 from 865, we get 125.
Append the next digit (3) from the dividend to 125 and continue with: 1253 / 148

On to step 4:
148 goes into 1253 8 times with a remainder of 69.
Write down 8 as next digit of the result. 
Result so far: 58.0
If we subtract 1184 from 1253, we get 69.
Append the next digit (9) from the dividend to 69 and continue with: 699 / 148

Step 5:
699 divided by 148 is 4 with a remainder of 107.
Record the quotient 4 as the next digit in the result. 
Result so far: 584.0
If we subtract 592 from 699, we get 107.
Fetch the next digit (3) from the dividend, attach it to 107 and continue: 1073 / 148

Going ahead to step 6:
148 goes into 1073 7 times with a remainder of 37.
The next digit of our result is 7. 
Result so far: 5847.0
Subtracting 1036 from 1073 leaves us with 37.
Bring next digit (9) of the dividend behind the 37 and repeat the process: 379 / 148

Going ahead to step 7:
148 goes into 379 2 times with a remainder of 83.
The number 2 becomes the next digit in our result. 
Result so far: 58472.0
If we take 296 away from 379, we end up with 83.
Bring next digit (6) of the dividend behind the 83 and repeat the process: 836 / 148

Step 8:
148 goes into 836 5 times with a remainder of 96.
The next digit of our result is 5. 
Result so far: 584725.0
If we take 740 away from 836, we end up with 96.
Since there are no more digits in the dividend, we add a zero to the remainder making it 960, and continue the process.

Let's proceed to step 9:
When dividing 960 by 148, we get 6 with a remainder of 72.
Put 6 as the next digit of the answer. 
Result so far: 584725.6
Subtracting 888 from 960 leaves us 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.

Going ahead to step 10:
720 divided by 148 is 4 with a remainder of 128.
The next digit of our result is 4. 
Result so far: 584725.64
The remainder is 128 after subtracting 592 from 720.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1280, and continue the process.

Let's proceed to step 11:
If we divide 1280 by 148, we get 8 and a remainder of 96.
Put 8 as the next digit of the answer. 
Result so far: 584725.648
Subtracting 1184 from 1280 leaves us with 96.
Since there are no more digits in the dividend, we add a zero to the remainder making it 960, and continue the process.

On to step 12:
148 can be fit into 960 6 times, resulting in a remainder of 72.
Write down 6 as next digit of the result. 
Result so far: 584725.6486
Subtracting 888 from 960 leaves us 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.

Going ahead to step 13:
720 divided by 148 is 4 with a remainder of 128.
The next digit of our result is 4. 
Result so far: 584725.64864
The remainder is 128 after subtracting 592 from 720.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1280, and continue the process.

Step 14:
148 goes into 1280 8 times with a remainder of 96.
Use 8 as the next digit of our solution. 
Result so far: 584725.648648
If we subtract 1184 from 1280, we 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.

Step 15:
148 can be fit into 960 6 times, resulting in a remainder of 72.
Use 6 as the next digit of our solution. 
Result so far: 584725.6486486
Subtracting 888 from 960 leaves us 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.

Moving on to step 16:
720 divided by 148 is 4 with a remainder of 128.
Write down 4 as next digit of the result. 
Result so far: 584725.64864864
Subtracting 592 from 720 leaves us 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.

After the division, we end up with 584725.64864864 and a remainder of 1.28e-07.
