We look at the division of 86643278 by 146 
Our goal is to divide 86643278 by 146.

Going ahead to step 1:
146 goes into 8 0 times with a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Take the next digit (6) from the dividend and append it to 8, then repeat: 86 / 146

Let's proceed to step 2:
86 divided by 146 is 0 with a remainder of 86.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 86 leaves us with 86.
Include the next digit (6) from the dividend after 86, then repeat: 866 / 146

On to step 3:
866 divided by 146 is 5 with a remainder of 136.
Record the quotient 5 as the next digit in the result. 
Result so far: 5.0
The remainder is 136 after subtracting 730 from 866.
Fetch the next digit (4) from the dividend, attach it to 136 and continue: 1364 / 146

Step 4:
146 goes into 1364 9 times with a remainder of 50.
Record the quotient 9 as the next digit in the result. 
Result so far: 59.0
If we subtract 1314 from 1364, we get 50.
Take the next digit (3) from the dividend and append it to 50, then repeat: 503 / 146

Moving on to step 5:
If we divide 503 by 146, we get 3 and a remainder of 65.
The next digit of our result is 3. 
Result so far: 593.0
If we subtract 438 from 503, we get 65.
Include the next digit (2) from the dividend after 65, then repeat: 652 / 146

Let's proceed to step 6:
652 divided by 146 is 4 with a remainder of 68.
Put 4 as the next digit of the answer. 
Result so far: 5934.0
The remainder is 68 after subtracting 584 from 652.
Include the next digit (7) from the dividend after 68, then repeat: 687 / 146

Let's proceed to step 7:
687 divided by 146 is 4 with a remainder of 103.
Record the quotient 4 as the next digit in the result. 
Result so far: 59344.0
The remainder is 103 after subtracting 584 from 687.
Grab the next digit (8) from the dividend, add it to 103, then carry on: 1038 / 146

Going ahead to step 8:
146 goes into 1038 7 times with a remainder of 16.
Put 7 as the next digit of the answer. 
Result so far: 593447.0
If we subtract 1022 from 1038, we get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Moving on to step 9:
If we divide 160 by 146, we get 1 and a remainder of 14.
The number 1 becomes the next digit in our result. 
Result so far: 593447.1
If we take 146 away from 160, we end up with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Let's proceed to step 10:
When dividing 140 by 146, we get 0 with a remainder of 140.
Use 0 as the next digit of our solution. 
Result so far: 593447.1
If we take 0 away from 140, we end up with 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

Step 11:
The number 146 fits into 1400 9 times, leaving a remainder of 86.
The number 9 becomes the next digit in our result. 
Result so far: 593447.109
The remainder is 86 after subtracting 1314 from 1400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 860, and continue the process.

Let's proceed to step 12:
The number 146 fits into 860 5 times, leaving a remainder of 130.
Use 5 as the next digit of our solution. 
Result so far: 593447.1095
Deduct 730 from 860 and we're left with 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

Going ahead to step 13:
The number 146 fits into 1300 8 times, leaving a remainder of 132.
Write down 8 as next digit of the result. 
Result so far: 593447.10958
Subtract 1168 from 1300 to get 132.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1320, and continue the process.

Step 14:
146 can be fit into 1320 9 times, resulting in a remainder of 6.
Write down 9 as next digit of the result. 
Result so far: 593447.109589
Subtract 1314 from 1320 to get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Let's proceed to step 15:
146 goes into 60 0 times with a remainder of 60.
Use 0 as the next digit of our solution. 
Result so far: 593447.109589
If we subtract 0 from 60, we get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Moving on to step 16:
When dividing 600 by 146, we get 4 with a remainder of 16.
Write down 4 as next digit of the result. 
Result so far: 593447.10958904
Deduct 584 from 600 and we're left with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

The final result is 593447.10958904 with a remainder of 1.6e-08.
