We're dividing 13809107 by 354 
We want to divide 13809107 by 354.

Step 1:
354 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.
Take the next digit (3) from the dividend and append it to 1, then repeat: 13 / 354

Moving on to step 2:
The number 354 fits into 13 0 times, leaving a remainder of 13.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 13 after subtracting 0 from 13.
Append the next digit (8) from the dividend to 13 and continue with: 138 / 354

Advancing to step 3:
When dividing 138 by 354, we get 0 with a remainder of 138.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 138, we end up with 138.
Bring next digit (0) of the dividend behind the 138 and repeat the process: 1380 / 354

Step 4:
The number 354 fits into 1380 3 times, leaving a remainder of 318.
Write down 3 as next digit of the result. 
Result so far: 3.0
Deduct 1062 from 1380 and we're left with 318.
Grab the next digit (9) from the dividend, add it to 318, then carry on: 3189 / 354

Let's proceed to step 5:
354 goes into 3189 9 times with a remainder of 3.
The number 9 becomes the next digit in our result. 
Result so far: 39.0
The remainder is 3 after subtracting 3186 from 3189.
Take the next digit (1) from the dividend and append it to 3, then repeat: 31 / 354

Advancing to step 6:
354 can be fit into 31 0 times, resulting in a remainder of 31.
Use 0 as the next digit of our solution. 
Result so far: 390.0
If we take 0 away from 31, we end up with 31.
Grab the next digit (0) from the dividend, add it to 31, then carry on: 310 / 354

Going ahead to step 7:
354 can be fit into 310 0 times, resulting in a remainder of 310.
Write down 0 as next digit of the result. 
Result so far: 3900.0
Subtracting 0 from 310 leaves us with 310.
Grab the next digit (7) from the dividend, add it to 310, then carry on: 3107 / 354

Moving on to step 8:
354 goes into 3107 8 times with a remainder of 275.
The number 8 becomes the next digit in our result. 
Result so far: 39008.0
Subtract 2832 from 3107 to get 275.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2750, and continue the process.

Advancing to step 9:
The number 354 fits into 2750 7 times, leaving a remainder of 272.
Write down 7 as next digit of the result. 
Result so far: 39008.7
Deduct 2478 from 2750 and we're left with 272.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2720, and continue the process.

Let's proceed to step 10:
354 goes into 2720 7 times with a remainder of 242.
Write down 7 as next digit of the result. 
Result so far: 39008.77
The remainder is 242 after subtracting 2478 from 2720.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2420, and continue the process.

In conclusion, the division gives 39008.77 with a balance of 0.242.
