We're dividing 336891 by 8 
We're looking to find how many times 8 goes into 336891.

Moving on to step 1:
When dividing 3 by 8, we get 0 with a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Grab the next digit (3) from the dividend, add it to 3, then carry on: 33 / 8

Advancing to step 2:
The number 8 fits into 33 4 times, leaving a remainder of 1.
Use 4 as the next digit of our solution. 
Result so far: 4.0
The remainder is 1 after subtracting 32 from 33.
Take the next digit (6) from the dividend and append it to 1, then repeat: 16 / 8

Advancing to step 3:
8 goes into 16 2 times with a remainder of 0.
Record the quotient 2 as the next digit in the result. 
Result so far: 42.0
Subtracting 16 from 16 leaves us with 0.
Grab the next digit (8) from the dividend, add it to 0, then carry on: 8 / 8

Advancing to step 4:
The number 8 fits into 8 1 times, leaving a remainder of 0.
Write down 1 as next digit of the result. 
Result so far: 421.0
Subtract 8 from 8 to get 0.
Bring next digit (9) of the dividend behind the 0 and repeat the process: 9 / 8

Moving on to step 5:
8 can be fit into 9 1 times, resulting in a remainder of 1.
Put 1 as the next digit of the answer. 
Result so far: 4211.0
Subtract 8 from 9 to get 1.
Bring next digit (1) of the dividend behind the 1 and repeat the process: 11 / 8

Moving on to step 6:
If we divide 11 by 8, we get 1 and a remainder of 3.
Use 1 as the next digit of our solution. 
Result so far: 42111.0
Subtract 8 from 11 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.

Step 7:
When dividing 30 by 8, we get 3 with a remainder of 6.
Put 3 as the next digit of the answer. 
Result so far: 42111.3
Deduct 24 from 30 and we're left with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Advancing to step 8:
When dividing 60 by 8, we get 7 with a remainder of 4.
Put 7 as the next digit of the answer. 
Result so far: 42111.37
Subtract 56 from 60 to 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:
8 goes into 40 5 times with a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 42111.375
The remainder is 0 after subtracting 40 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to 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: 42111.375
If we subtract 0 from 0, we get 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 11:
When dividing 0 by 8, we get 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 42111.375
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.

After the division, we end up with 42111.375 and a remainder of 0.0.
