139651 ÷ 8 
We're looking to find how many times 8 goes into 139651.

Step 1:
8 can be fit into 1 0 times, resulting in a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Include the next digit (3) from the dividend after 1, then repeat: 13 / 8

Going ahead to step 2:
The number 8 fits into 13 1 times, leaving a remainder of 5.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtracting 8 from 13 leaves us with 5.
Fetch the next digit (9) from the dividend, attach it to 5 and continue: 59 / 8

Moving on to step 3:
When dividing 59 by 8, we get 7 with a remainder of 3.
Put 7 as the next digit of the answer. 
Result so far: 17.0
Subtract 56 from 59 to get 3.
Take the next digit (6) from the dividend and append it to 3, then repeat: 36 / 8

Step 4:
If we divide 36 by 8, we get 4 and a remainder of 4.
Record the quotient 4 as the next digit in the result. 
Result so far: 174.0
Subtracting 32 from 36 leaves us with 4.
Include the next digit (5) from the dividend after 4, then repeat: 45 / 8

Moving on to step 5:
If we divide 45 by 8, we get 5 and a remainder of 5.
Use 5 as the next digit of our solution. 
Result so far: 1745.0
The remainder is 5 after subtracting 40 from 45.
Bring next digit (1) of the dividend behind the 5 and repeat the process: 51 / 8

Advancing to step 6:
51 divided by 8 is 6 with a remainder of 3.
The number 6 becomes the next digit in our result. 
Result so far: 17456.0
Subtract 48 from 51 to get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

On to step 7:
When dividing 30 by 8, we get 3 with a remainder of 6.
The number 3 becomes the next digit in our result. 
Result so far: 17456.3
The remainder is 6 after subtracting 24 from 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Going ahead to step 8:
If we divide 60 by 8, we get 7 and a remainder of 4.
The number 7 becomes the next digit in our result. 
Result so far: 17456.37
If we subtract 56 from 60, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Going ahead to step 9:
When dividing 40 by 8, we get 5 with a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 17456.375
Subtracting 40 from 40 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 10:
When dividing 0 by 8, we get 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 17456.375
Deduct 0 from 0 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 11:
8 goes into 0 0 times with a remainder of 0.
The next digit of our result is 0. 
Result so far: 17456.375
Subtracting 0 from 0 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Our division results in 17456.375 with a remaining 0.0.
