We divide 3874676 by 620
Our goal is to divide 3874676 by 620.

Advancing to step 1:
If we divide 3 by 620, we get 0 and a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Bring next digit (8) of the dividend behind the 3 and repeat the process: 38 / 620

Moving on to step 2:
When dividing 38 by 620, we get 0 with a remainder of 38.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 38, we get 38.
Include the next digit (7) from the dividend after 38, then repeat: 387 / 620

Let's proceed to step 3:
387 divided by 620 is 0 with a remainder of 387.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 387 after subtracting 0 from 387.
Append the next digit (4) from the dividend to 387 and continue with: 3874 / 620

Going ahead to step 4:
The number 620 fits into 3874 6 times, leaving a remainder of 154.
The next digit of our result is 6. 
Result so far: 6.0
Subtracting 3720 from 3874 leaves us with 154.
Bring next digit (6) of the dividend behind the 154 and repeat the process: 1546 / 620

Let's proceed to step 5:
620 goes into 1546 2 times with a remainder of 306.
The next digit of our result is 2. 
Result so far: 62.0
If we take 1240 away from 1546, we end up with 306.
Append the next digit (7) from the dividend to 306 and continue with: 3067 / 620

Going ahead to step 6:
620 goes into 3067 4 times with a remainder of 587.
The number 4 becomes the next digit in our result. 
Result so far: 624.0
Subtract 2480 from 3067 to get 587.
Take the next digit (6) from the dividend and append it to 587, then repeat: 5876 / 620

On to step 7:
5876 divided by 620 is 9 with a remainder of 296.
Write down 9 as next digit of the result. 
Result so far: 6249.0
Subtract 5580 from 5876 to get 296.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2960, and continue the process.

Let's proceed to step 8:
620 can be fit into 2960 4 times, resulting in a remainder of 480.
Use 4 as the next digit of our solution. 
Result so far: 6249.4
The remainder is 480 after subtracting 2480 from 2960.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4800, and continue the process.

Step 9:
If we divide 4800 by 620, we get 7 and a remainder of 460.
Use 7 as the next digit of our solution. 
Result so far: 6249.47
Subtract 4340 from 4800 to get 460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4600, and continue the process.

Step 10:
620 can be fit into 4600 7 times, resulting in a remainder of 260.
Write down 7 as next digit of the result. 
Result so far: 6249.477
The remainder is 260 after subtracting 4340 from 4600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2600, and continue the process.

The final outcome is 6249.477, with a leftover of 0.026.
