We look at the division of 86066430 by 623 
We're looking to find how many times 623 goes into 86066430.

Advancing to step 1:
623 goes into 8 0 times with a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Append the next digit (6) from the dividend to 8 and continue with: 86 / 623

Step 2:
When dividing 86 by 623, we get 0 with a remainder of 86.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 86 leaves us with 86.
Bring next digit (0) of the dividend behind the 86 and repeat the process: 860 / 623

Let's proceed to step 3:
623 goes into 860 1 times with a remainder of 237.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we subtract 623 from 860, we get 237.
Include the next digit (6) from the dividend after 237, then repeat: 2376 / 623

Advancing to step 4:
When dividing 2376 by 623, we get 3 with a remainder of 507.
Use 3 as the next digit of our solution. 
Result so far: 13.0
Subtracting 1869 from 2376 leaves us with 507.
Append the next digit (6) from the dividend to 507 and continue with: 5076 / 623

Let's proceed to step 5:
The number 623 fits into 5076 8 times, leaving a remainder of 92.
Write down 8 as next digit of the result. 
Result so far: 138.0
Subtracting 4984 from 5076 leaves us with 92.
Grab the next digit (4) from the dividend, add it to 92, then carry on: 924 / 623

On to step 6:
When dividing 924 by 623, we get 1 with a remainder of 301.
The number 1 becomes the next digit in our result. 
Result so far: 1381.0
The remainder is 301 after subtracting 623 from 924.
Append the next digit (3) from the dividend to 301 and continue with: 3013 / 623

Step 7:
3013 divided by 623 is 4 with a remainder of 521.
Record the quotient 4 as the next digit in the result. 
Result so far: 13814.0
Subtracting 2492 from 3013 leaves us with 521.
Append the next digit (0) from the dividend to 521 and continue with: 5210 / 623

Advancing to step 8:
5210 divided by 623 is 8 with a remainder of 226.
Use 8 as the next digit of our solution. 
Result so far: 138148.0
Subtracting 4984 from 5210 leaves us with 226.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2260, and continue the process.

On to step 9:
The number 623 fits into 2260 3 times, leaving a remainder of 391.
Write down 3 as next digit of the result. 
Result so far: 138148.3
Subtracting 1869 from 2260 leaves us with 391.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3910, and continue the process.

Advancing to step 10:
The number 623 fits into 3910 6 times, leaving a remainder of 172.
The next digit of our result is 6. 
Result so far: 138148.36
If we subtract 3738 from 3910, we get 172.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1720, and continue the process.

Advancing to step 11:
The number 623 fits into 1720 2 times, leaving a remainder of 474.
The number 2 becomes the next digit in our result. 
Result so far: 138148.362
Subtracting 1246 from 1720 leaves us with 474.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4740, and continue the process.

Moving on to step 12:
623 can be fit into 4740 7 times, resulting in a remainder of 379.
Record the quotient 7 as the next digit in the result. 
Result so far: 138148.3627
Subtracting 4361 from 4740 leaves us with 379.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3790, and continue the process.

Step 13:
If we divide 3790 by 623, we get 6 and a remainder of 52.
Put 6 as the next digit of the answer. 
Result so far: 138148.36276
If we subtract 3738 from 3790, we get 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Moving on to step 14:
The number 623 fits into 520 0 times, leaving a remainder of 520.
The number 0 becomes the next digit in our result. 
Result so far: 138148.36276
If we take 0 away from 520, we end up with 520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5200, and continue the process.

On to step 15:
623 can be fit into 5200 8 times, resulting in a remainder of 216.
Put 8 as the next digit of the answer. 
Result so far: 138148.3627608
If we subtract 4984 from 5200, we get 216.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2160, and continue the process.

Advancing to step 16:
623 can be fit into 2160 3 times, resulting in a remainder of 291.
Use 3 as the next digit of our solution. 
Result so far: 138148.36276083
If we subtract 1869 from 2160, we get 291.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2910, and continue the process.

Our division results in 138148.36276083 with a remaining 2.91e-07.
