53438065 ÷ 308 
We want to divide 53438065 by 308.

Advancing to step 1:
If we divide 5 by 308, we get 0 and a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Append the next digit (3) from the dividend to 5 and continue with: 53 / 308

Moving on to step 2:
53 divided by 308 is 0 with a remainder of 53.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 53 to get 53.
Bring next digit (4) of the dividend behind the 53 and repeat the process: 534 / 308

Step 3:
308 goes into 534 1 times with a remainder of 226.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Deduct 308 from 534 and we're left with 226.
Bring next digit (3) of the dividend behind the 226 and repeat the process: 2263 / 308

Let's proceed to step 4:
When dividing 2263 by 308, we get 7 with a remainder of 107.
Put 7 as the next digit of the answer. 
Result so far: 17.0
If we subtract 2156 from 2263, we get 107.
Append the next digit (8) from the dividend to 107 and continue with: 1078 / 308

Let's proceed to step 5:
308 goes into 1078 3 times with a remainder of 154.
Put 3 as the next digit of the answer. 
Result so far: 173.0
Deduct 924 from 1078 and we're left with 154.
Take the next digit (0) from the dividend and append it to 154, then repeat: 1540 / 308

On to step 6:
308 goes into 1540 5 times with a remainder of 0.
The next digit of our result is 5. 
Result so far: 1735.0
The remainder is 0 after subtracting 1540 from 1540.
Append the next digit (6) from the dividend to 0 and continue with: 6 / 308

On to step 7:
308 can be fit into 6 0 times, resulting in a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 17350.0
Deduct 0 from 6 and we're left with 6.
Fetch the next digit (5) from the dividend, attach it to 6 and continue: 65 / 308

Advancing to step 8:
65 divided by 308 is 0 with a remainder of 65.
Put 0 as the next digit of the answer. 
Result so far: 173500.0
Subtract 0 from 65 to get 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

Moving on to step 9:
The number 308 fits into 650 2 times, leaving a remainder of 34.
Write down 2 as next digit of the result. 
Result so far: 173500.2
Subtracting 616 from 650 leaves us with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Going ahead to step 10:
340 divided by 308 is 1 with a remainder of 32.
Record the quotient 1 as the next digit in the result. 
Result so far: 173500.21
If we subtract 308 from 340, we get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Let's proceed to step 11:
320 divided by 308 is 1 with a remainder of 12.
The next digit of our result is 1. 
Result so far: 173500.211
Subtracting 308 from 320 leaves us with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Our division results in 173500.211 with a remaining 0.0012.
