15970553 ÷ 308 
We want to divide 15970553 by 308.

Let's proceed to step 1:
When dividing 1 by 308, we get 0 with a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Grab the next digit (5) from the dividend, add it to 1, then carry on: 15 / 308

On to step 2:
308 can be fit into 15 0 times, resulting in a remainder of 15.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 15 to get 15.
Fetch the next digit (9) from the dividend, attach it to 15 and continue: 159 / 308

Step 3:
159 divided by 308 is 0 with a remainder of 159.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 159 to get 159.
Take the next digit (7) from the dividend and append it to 159, then repeat: 1597 / 308

Advancing to step 4:
When dividing 1597 by 308, we get 5 with a remainder of 57.
Put 5 as the next digit of the answer. 
Result so far: 5.0
Subtract 1540 from 1597 to get 57.
Take the next digit (0) from the dividend and append it to 57, then repeat: 570 / 308

Moving on to step 5:
The number 308 fits into 570 1 times, leaving a remainder of 262.
Use 1 as the next digit of our solution. 
Result so far: 51.0
If we subtract 308 from 570, we get 262.
Fetch the next digit (5) from the dividend, attach it to 262 and continue: 2625 / 308

Let's proceed to step 6:
If we divide 2625 by 308, we get 8 and a remainder of 161.
Put 8 as the next digit of the answer. 
Result so far: 518.0
Subtract 2464 from 2625 to get 161.
Take the next digit (5) from the dividend and append it to 161, then repeat: 1615 / 308

On to step 7:
When dividing 1615 by 308, we get 5 with a remainder of 75.
The number 5 becomes the next digit in our result. 
Result so far: 5185.0
The remainder is 75 after subtracting 1540 from 1615.
Include the next digit (3) from the dividend after 75, then repeat: 753 / 308

Let's proceed to step 8:
308 goes into 753 2 times with a remainder of 137.
The number 2 becomes the next digit in our result. 
Result so far: 51852.0
The remainder is 137 after subtracting 616 from 753.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1370, and continue the process.

Step 9:
If we divide 1370 by 308, we get 4 and a remainder of 138.
Use 4 as the next digit of our solution. 
Result so far: 51852.4
If we take 1232 away from 1370, we end up with 138.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1380, and continue the process.

Step 10:
The number 308 fits into 1380 4 times, leaving a remainder of 148.
The next digit of our result is 4. 
Result so far: 51852.44
Subtracting 1232 from 1380 leaves us with 148.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1480, and continue the process.

After the division, we end up with 51852.44 and a remainder of 0.148.
