We look at the division of 86341666 by 145 
We want to figure out the number of times 86341666 can be divided by 145.

Advancing to step 1:
If we divide 8 by 145, we get 0 and 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.
Bring next digit (6) of the dividend behind the 8 and repeat the process: 86 / 145

Going ahead to step 2:
If we divide 86 by 145, we get 0 and a remainder of 86.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 86, we end up with 86.
Fetch the next digit (3) from the dividend, attach it to 86 and continue: 863 / 145

Advancing to step 3:
The number 145 fits into 863 5 times, leaving a remainder of 138.
Record the quotient 5 as the next digit in the result. 
Result so far: 5.0
If we subtract 725 from 863, we get 138.
Fetch the next digit (4) from the dividend, attach it to 138 and continue: 1384 / 145

Moving on to step 4:
1384 divided by 145 is 9 with a remainder of 79.
The next digit of our result is 9. 
Result so far: 59.0
Subtract 1305 from 1384 to get 79.
Include the next digit (1) from the dividend after 79, then repeat: 791 / 145

Advancing to step 5:
When dividing 791 by 145, we get 5 with a remainder of 66.
Use 5 as the next digit of our solution. 
Result so far: 595.0
If we subtract 725 from 791, we get 66.
Take the next digit (6) from the dividend and append it to 66, then repeat: 666 / 145

Advancing to step 6:
145 can be fit into 666 4 times, resulting in a remainder of 86.
The number 4 becomes the next digit in our result. 
Result so far: 5954.0
If we subtract 580 from 666, we get 86.
Take the next digit (6) from the dividend and append it to 86, then repeat: 866 / 145

Let's proceed to step 7:
If we divide 866 by 145, we get 5 and a remainder of 141.
Write down 5 as next digit of the result. 
Result so far: 59545.0
Deduct 725 from 866 and we're left with 141.
Include the next digit (6) from the dividend after 141, then repeat: 1416 / 145

Step 8:
The number 145 fits into 1416 9 times, leaving a remainder of 111.
Use 9 as the next digit of our solution. 
Result so far: 595459.0
Deduct 1305 from 1416 and we're left with 111.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1110, and continue the process.

On to step 9:
When dividing 1110 by 145, we get 7 with a remainder of 95.
Record the quotient 7 as the next digit in the result. 
Result so far: 595459.7
If we take 1015 away from 1110, we end up with 95.
Since there are no more digits in the dividend, we add a zero to the remainder making it 950, and continue the process.

Advancing to step 10:
If we divide 950 by 145, we get 6 and a remainder of 80.
The number 6 becomes the next digit in our result. 
Result so far: 595459.76
The remainder is 80 after subtracting 870 from 950.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Going ahead to step 11:
When dividing 800 by 145, we get 5 with a remainder of 75.
Write down 5 as next digit of the result. 
Result so far: 595459.765
Subtracting 725 from 800 leaves us with 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Moving on to step 12:
If we divide 750 by 145, we get 5 and a remainder of 25.
Put 5 as the next digit of the answer. 
Result so far: 595459.7655
The remainder is 25 after subtracting 725 from 750.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

The final result is 595459.7655 with a remainder of 0.00025.
