145231 divided by 78 
Let's see how many times 78 fits into 145231.

Moving on to step 1:
1 divided by 78 is 0 with a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Append the next digit (4) from the dividend to 1 and continue with: 14 / 78

On to step 2:
When dividing 14 by 78, we get 0 with a remainder of 14.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 14 and we're left with 14.
Include the next digit (5) from the dividend after 14, then repeat: 145 / 78

Let's proceed to step 3:
78 goes into 145 1 times with a remainder of 67.
The next digit of our result is 1. 
Result so far: 1.0
If we take 78 away from 145, we end up with 67.
Grab the next digit (2) from the dividend, add it to 67, then carry on: 672 / 78

Let's proceed to step 4:
78 can be fit into 672 8 times, resulting in a remainder of 48.
The next digit of our result is 8. 
Result so far: 18.0
If we subtract 624 from 672, we get 48.
Grab the next digit (3) from the dividend, add it to 48, then carry on: 483 / 78

Going ahead to step 5:
483 divided by 78 is 6 with a remainder of 15.
Record the quotient 6 as the next digit in the result. 
Result so far: 186.0
If we take 468 away from 483, we end up with 15.
Grab the next digit (1) from the dividend, add it to 15, then carry on: 151 / 78

Step 6:
When dividing 151 by 78, we get 1 with a remainder of 73.
The next digit of our result is 1. 
Result so far: 1861.0
Deduct 78 from 151 and we're left with 73.
Since there are no more digits in the dividend, we add a zero to the remainder making it 730, and continue the process.

Advancing to step 7:
78 can be fit into 730 9 times, resulting in a remainder of 28.
The number 9 becomes the next digit in our result. 
Result so far: 1861.9
If we subtract 702 from 730, we get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Step 8:
78 can be fit into 280 3 times, resulting in a remainder of 46.
Record the quotient 3 as the next digit in the result. 
Result so far: 1861.93
If we take 234 away from 280, we end up 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.

Moving on to step 9:
460 divided by 78 is 5 with a remainder of 70.
Use 5 as the next digit of our solution. 
Result so far: 1861.935
Subtract 390 from 460 to get 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

On to step 10:
700 divided by 78 is 8 with a remainder of 76.
Write down 8 as next digit of the result. 
Result so far: 1861.9358
Subtract 624 from 700 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.

On to step 11:
If we divide 760 by 78, we get 9 and a remainder of 58.
Record the quotient 9 as the next digit in the result. 
Result so far: 1861.93589
The remainder is 58 after subtracting 702 from 760.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

On to step 12:
When dividing 580 by 78, we get 7 with a remainder of 34.
Write down 7 as next digit of the result. 
Result so far: 1861.935897
Deduct 546 from 580 and we're left with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Moving on to step 13:
340 divided by 78 is 4 with a remainder of 28.
The next digit of our result is 4. 
Result so far: 1861.9358974
Deduct 312 from 340 and we're left with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Step 14:
When dividing 280 by 78, we get 3 with a remainder of 46.
The number 3 becomes the next digit in our result. 
Result so far: 1861.93589743
Deduct 234 from 280 and we're left 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.

The final result is 1861.93589743 with a remainder of 4.6e-08.
