Let's divide 7834390 by 3
Let's see how many times 3 fits into 7834390.

Going ahead to step 1:
3 goes into 7 2 times with a remainder of 1.
The next digit of our result is 2. 
Result so far: 2.0
If we subtract 6 from 7, we get 1.
Fetch the next digit (8) from the dividend, attach it to 1 and continue: 18 / 3

Moving on to step 2:
When dividing 18 by 3, we get 6 with a remainder of 0.
Write down 6 as next digit of the result. 
Result so far: 26.0
Subtracting 18 from 18 leaves us with 0.
Append the next digit (3) from the dividend to 0 and continue with: 3 / 3

On to step 3:
3 divided by 3 is 1 with a remainder of 0.
Write down 1 as next digit of the result. 
Result so far: 261.0
Subtracting 3 from 3 leaves us with 0.
Fetch the next digit (4) from the dividend, attach it to 0 and continue: 4 / 3

Advancing to step 4:
The number 3 fits into 4 1 times, leaving a remainder of 1.
Put 1 as the next digit of the answer. 
Result so far: 2611.0
Subtract 3 from 4 to get 1.
Fetch the next digit (3) from the dividend, attach it to 1 and continue: 13 / 3

Let's proceed to step 5:
When dividing 13 by 3, we get 4 with a remainder of 1.
The next digit of our result is 4. 
Result so far: 26114.0
Subtracting 12 from 13 leaves us with 1.
Take the next digit (9) from the dividend and append it to 1, then repeat: 19 / 3

Moving on to step 6:
19 divided by 3 is 6 with a remainder of 1.
Write down 6 as next digit of the result. 
Result so far: 261146.0
Subtract 18 from 19 to get 1.
Take the next digit (0) from the dividend and append it to 1, then repeat: 10 / 3

Step 7:
The number 3 fits into 10 3 times, leaving a remainder of 1.
Use 3 as the next digit of our solution. 
Result so far: 2611463.0
If we take 9 away from 10, we end up with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Let's proceed to step 8:
3 can be fit into 10 3 times, resulting in a remainder of 1.
Use 3 as the next digit of our solution. 
Result so far: 2611463.3
Deduct 9 from 10 and we're left with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

On to step 9:
When dividing 10 by 3, we get 3 with a remainder of 1.
Put 3 as the next digit of the answer. 
Result so far: 2611463.33
Subtract 9 from 10 to get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

The final outcome is 2611463.33, with a leftover of 0.001.
