We're dividing 13409753 by 904 
We want to divide 13409753 by 904.

On to step 1:
The number 904 fits into 1 0 times, leaving a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Grab the next digit (3) from the dividend, add it to 1, then carry on: 13 / 904

Going ahead to step 2:
904 goes into 13 0 times with a remainder of 13.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 13, we get 13.
Take the next digit (4) from the dividend and append it to 13, then repeat: 134 / 904

Advancing to step 3:
If we divide 134 by 904, we get 0 and a remainder of 134.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 134 and we're left with 134.
Bring next digit (0) of the dividend behind the 134 and repeat the process: 1340 / 904

Moving on to step 4:
1340 divided by 904 is 1 with a remainder of 436.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtracting 904 from 1340 leaves us with 436.
Take the next digit (9) from the dividend and append it to 436, then repeat: 4369 / 904

Going ahead to step 5:
904 can be fit into 4369 4 times, resulting in a remainder of 753.
The next digit of our result is 4. 
Result so far: 14.0
The remainder is 753 after subtracting 3616 from 4369.
Bring next digit (7) of the dividend behind the 753 and repeat the process: 7537 / 904

Moving on to step 6:
The number 904 fits into 7537 8 times, leaving a remainder of 305.
Use 8 as the next digit of our solution. 
Result so far: 148.0
Subtract 7232 from 7537 to get 305.
Fetch the next digit (5) from the dividend, attach it to 305 and continue: 3055 / 904

Let's proceed to step 7:
904 goes into 3055 3 times with a remainder of 343.
The number 3 becomes the next digit in our result. 
Result so far: 1483.0
If we take 2712 away from 3055, we end up with 343.
Take the next digit (3) from the dividend and append it to 343, then repeat: 3433 / 904

Going ahead to step 8:
The number 904 fits into 3433 3 times, leaving a remainder of 721.
The next digit of our result is 3. 
Result so far: 14833.0
Deduct 2712 from 3433 and we're left with 721.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7210, and continue the process.

Let's proceed to step 9:
904 goes into 7210 7 times with a remainder of 882.
The next digit of our result is 7. 
Result so far: 14833.7
Subtract 6328 from 7210 to get 882.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8820, and continue the process.

Step 10:
If we divide 8820 by 904, we get 9 and a remainder of 684.
Write down 9 as next digit of the result. 
Result so far: 14833.79
If we subtract 8136 from 8820, we get 684.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6840, and continue the process.

Step 11:
If we divide 6840 by 904, we get 7 and a remainder of 512.
Write down 7 as next digit of the result. 
Result so far: 14833.797
If we subtract 6328 from 6840, we get 512.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5120, and continue the process.

Step 12:
904 goes into 5120 5 times with a remainder of 600.
Record the quotient 5 as the next digit in the result. 
Result so far: 14833.7975
If we take 4520 away from 5120, we end up with 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6000, and continue the process.

Let's proceed to step 13:
If we divide 6000 by 904, we get 6 and a remainder of 576.
The next digit of our result is 6. 
Result so far: 14833.79756
The remainder is 576 after subtracting 5424 from 6000.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5760, and continue the process.

Moving on to step 14:
904 can be fit into 5760 6 times, resulting in a remainder of 336.
The next digit of our result is 6. 
Result so far: 14833.797566
If we take 5424 away from 5760, we end up with 336.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3360, and continue the process.

After the division, we end up with 14833.797566 and a remainder of 3.36e-05.
