We're dividing 145370 by 86 
We want to divide 145370 by 86.

Advancing to step 1:
1 divided by 86 is 0 with a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Append the next digit (4) from the dividend to 1 and continue with: 14 / 86

Step 2:
86 can be fit into 14 0 times, resulting in a remainder of 14.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 14 leaves us with 14.
Grab the next digit (5) from the dividend, add it to 14, then carry on: 145 / 86

Advancing to step 3:
If we divide 145 by 86, we get 1 and a remainder of 59.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtract 86 from 145 to get 59.
Fetch the next digit (3) from the dividend, attach it to 59 and continue: 593 / 86

Going ahead to step 4:
The number 86 fits into 593 6 times, leaving a remainder of 77.
Write down 6 as next digit of the result. 
Result so far: 16.0
Subtract 516 from 593 to get 77.
Include the next digit (7) from the dividend after 77, then repeat: 777 / 86

Let's proceed to step 5:
86 goes into 777 9 times with a remainder of 3.
The number 9 becomes the next digit in our result. 
Result so far: 169.0
If we subtract 774 from 777, we get 3.
Take the next digit (0) from the dividend and append it to 3, then repeat: 30 / 86

Going ahead to step 6:
If we divide 30 by 86, we get 0 and a remainder of 30.
The number 0 becomes the next digit in our result. 
Result so far: 1690.0
If we take 0 away from 30, we end up with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Let's proceed to step 7:
86 can be fit into 300 3 times, resulting in a remainder of 42.
The next digit of our result is 3. 
Result so far: 1690.3
The remainder is 42 after subtracting 258 from 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Moving on to step 8:
86 can be fit into 420 4 times, resulting in a remainder of 76.
The number 4 becomes the next digit in our result. 
Result so far: 1690.34
Subtract 344 from 420 to get 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Let's proceed to step 9:
760 divided by 86 is 8 with a remainder of 72.
The number 8 becomes the next digit in our result. 
Result so far: 1690.348
If we take 688 away from 760, we end up 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.

Advancing to step 10:
86 goes into 720 8 times with a remainder of 32.
The next digit of our result is 8. 
Result so far: 1690.3488
Subtracting 688 from 720 leaves us with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

The quotient of the division is 1690.3488, and the remainder is 0.00032.
