3103123 ÷ 354 
We want to figure out the number of times 3103123 can be divided by 354.

Let's proceed to step 1:
When dividing 3 by 354, we get 0 with a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Take the next digit (1) from the dividend and append it to 3, then repeat: 31 / 354

On to step 2:
The number 354 fits into 31 0 times, leaving a remainder of 31.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 31 after subtracting 0 from 31.
Take the next digit (0) from the dividend and append it to 31, then repeat: 310 / 354

Going ahead to step 3:
The number 354 fits into 310 0 times, leaving a remainder of 310.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 310, we end up with 310.
Take the next digit (3) from the dividend and append it to 310, then repeat: 3103 / 354

Step 4:
354 goes into 3103 8 times with a remainder of 271.
Use 8 as the next digit of our solution. 
Result so far: 8.0
Subtract 2832 from 3103 to get 271.
Fetch the next digit (1) from the dividend, attach it to 271 and continue: 2711 / 354

Step 5:
354 goes into 2711 7 times with a remainder of 233.
Record the quotient 7 as the next digit in the result. 
Result so far: 87.0
Subtract 2478 from 2711 to get 233.
Take the next digit (2) from the dividend and append it to 233, then repeat: 2332 / 354

Step 6:
The number 354 fits into 2332 6 times, leaving a remainder of 208.
Put 6 as the next digit of the answer. 
Result so far: 876.0
Deduct 2124 from 2332 and we're left with 208.
Fetch the next digit (3) from the dividend, attach it to 208 and continue: 2083 / 354

Going ahead to step 7:
If we divide 2083 by 354, we get 5 and a remainder of 313.
Use 5 as the next digit of our solution. 
Result so far: 8765.0
If we subtract 1770 from 2083, we get 313.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3130, and continue the process.

On to step 8:
3130 divided by 354 is 8 with a remainder of 298.
Use 8 as the next digit of our solution. 
Result so far: 8765.8
The remainder is 298 after subtracting 2832 from 3130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2980, and continue the process.

Going ahead to step 9:
2980 divided by 354 is 8 with a remainder of 148.
Record the quotient 8 as the next digit in the result. 
Result so far: 8765.88
The remainder is 148 after subtracting 2832 from 2980.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1480, and continue the process.

The final result is 8765.88 with a remainder of 0.148.
