We're dividing 336406 by 91 
We want to divide 336406 by 91.

On to step 1:
When dividing 3 by 91, we get 0 with a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Include the next digit (3) from the dividend after 3, then repeat: 33 / 91

Going ahead to step 2:
91 goes into 33 0 times with a remainder of 33.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 33 to get 33.
Fetch the next digit (6) from the dividend, attach it to 33 and continue: 336 / 91

Advancing to step 3:
The number 91 fits into 336 3 times, leaving a remainder of 63.
Use 3 as the next digit of our solution. 
Result so far: 3.0
Subtract 273 from 336 to get 63.
Take the next digit (4) from the dividend and append it to 63, then repeat: 634 / 91

Going ahead to step 4:
The number 91 fits into 634 6 times, leaving a remainder of 88.
Put 6 as the next digit of the answer. 
Result so far: 36.0
The remainder is 88 after subtracting 546 from 634.
Include the next digit (0) from the dividend after 88, then repeat: 880 / 91

Advancing to step 5:
91 can be fit into 880 9 times, resulting in a remainder of 61.
Put 9 as the next digit of the answer. 
Result so far: 369.0
Subtract 819 from 880 to get 61.
Grab the next digit (6) from the dividend, add it to 61, then carry on: 616 / 91

Going ahead to step 6:
91 can be fit into 616 6 times, resulting in a remainder of 70.
Record the quotient 6 as the next digit in the result. 
Result so far: 3696.0
Subtract 546 from 616 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.

Moving on to step 7:
700 divided by 91 is 7 with a remainder of 63.
The next digit of our result is 7. 
Result so far: 3696.7
The remainder is 63 after subtracting 637 from 700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 630, and continue the process.

Moving on to step 8:
91 goes into 630 6 times with a remainder of 84.
Record the quotient 6 as the next digit in the result. 
Result so far: 3696.76
Subtracting 546 from 630 leaves us with 84.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

Let's proceed to step 9:
91 goes into 840 9 times with a remainder of 21.
The number 9 becomes the next digit in our result. 
Result so far: 3696.769
Subtracting 819 from 840 leaves us with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Moving on to step 10:
91 can be fit into 210 2 times, resulting in a remainder of 28.
Write down 2 as next digit of the result. 
Result so far: 3696.7692
Subtract 182 from 210 to 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.

Advancing to step 11:
280 divided by 91 is 3 with a remainder of 7.
Write down 3 as next digit of the result. 
Result so far: 3696.76923
If we subtract 273 from 280, we get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Step 12:
70 divided by 91 is 0 with a remainder of 70.
The number 0 becomes the next digit in our result. 
Result so far: 3696.76923
Subtracting 0 from 70 leaves us with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Going ahead to step 13:
91 can be fit into 700 7 times, resulting in a remainder of 63.
The number 7 becomes the next digit in our result. 
Result so far: 3696.7692307
Deduct 637 from 700 and we're left with 63.
Since there are no more digits in the dividend, we add a zero to the remainder making it 630, and continue the process.

Moving on to step 14:
91 can be fit into 630 6 times, resulting in a remainder of 84.
Record the quotient 6 as the next digit in the result. 
Result so far: 3696.76923076
If we subtract 546 from 630, we get 84.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

Our division results in 3696.76923076 with a remaining 8.4e-08.
