3394900 ÷ 690 
Let's see how many times 690 fits into 3394900.

Advancing to step 1:
690 can be fit into 3 0 times, resulting in a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Bring next digit (3) of the dividend behind the 3 and repeat the process: 33 / 690

Going ahead to step 2:
690 can be fit into 33 0 times, resulting in a remainder of 33.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 33 and we're left with 33.
Fetch the next digit (9) from the dividend, attach it to 33 and continue: 339 / 690

On to step 3:
The number 690 fits into 339 0 times, leaving a remainder of 339.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 339 to get 339.
Take the next digit (4) from the dividend and append it to 339, then repeat: 3394 / 690

Moving on to step 4:
The number 690 fits into 3394 4 times, leaving a remainder of 634.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
Subtracting 2760 from 3394 leaves us with 634.
Bring next digit (9) of the dividend behind the 634 and repeat the process: 6349 / 690

Step 5:
The number 690 fits into 6349 9 times, leaving a remainder of 139.
Record the quotient 9 as the next digit in the result. 
Result so far: 49.0
Subtracting 6210 from 6349 leaves us with 139.
Include the next digit (0) from the dividend after 139, then repeat: 1390 / 690

Let's proceed to step 6:
1390 divided by 690 is 2 with a remainder of 10.
Put 2 as the next digit of the answer. 
Result so far: 492.0
The remainder is 10 after subtracting 1380 from 1390.
Append the next digit (0) from the dividend to 10 and continue with: 100 / 690

Advancing to step 7:
The number 690 fits into 100 0 times, leaving a remainder of 100.
Put 0 as the next digit of the answer. 
Result so far: 4920.0
The remainder is 100 after subtracting 0 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Let's proceed to step 8:
The number 690 fits into 1000 1 times, leaving a remainder of 310.
The next digit of our result is 1. 
Result so far: 4920.1
Deduct 690 from 1000 and we're left with 310.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3100, and continue the process.

Step 9:
3100 divided by 690 is 4 with a remainder of 340.
Write down 4 as next digit of the result. 
Result so far: 4920.14
Deduct 2760 from 3100 and we're left with 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3400, and continue the process.

Step 10:
3400 divided by 690 is 4 with a remainder of 640.
The number 4 becomes the next digit in our result. 
Result so far: 4920.144
Deduct 2760 from 3400 and we're left with 640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6400, and continue the process.

The final result is 4920.144 with a remainder of 0.064.
