We look at the division of 4869139 by 406 
Let's see how many times 406 fits into 4869139.

Moving on to step 1:
If we divide 4 by 406, we get 0 and a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Bring next digit (8) of the dividend behind the 4 and repeat the process: 48 / 406

Going ahead to step 2:
The number 406 fits into 48 0 times, leaving a remainder of 48.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 48 to get 48.
Fetch the next digit (6) from the dividend, attach it to 48 and continue: 486 / 406

Advancing to step 3:
When dividing 486 by 406, we get 1 with a remainder of 80.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Deduct 406 from 486 and we're left with 80.
Append the next digit (9) from the dividend to 80 and continue with: 809 / 406

Going ahead to step 4:
406 goes into 809 1 times with a remainder of 403.
The number 1 becomes the next digit in our result. 
Result so far: 11.0
If we take 406 away from 809, we end up with 403.
Grab the next digit (1) from the dividend, add it to 403, then carry on: 4031 / 406

Going ahead to step 5:
When dividing 4031 by 406, we get 9 with a remainder of 377.
Record the quotient 9 as the next digit in the result. 
Result so far: 119.0
Deduct 3654 from 4031 and we're left with 377.
Grab the next digit (3) from the dividend, add it to 377, then carry on: 3773 / 406

Moving on to step 6:
The number 406 fits into 3773 9 times, leaving a remainder of 119.
The next digit of our result is 9. 
Result so far: 1199.0
The remainder is 119 after subtracting 3654 from 3773.
Bring next digit (9) of the dividend behind the 119 and repeat the process: 1199 / 406

Step 7:
When dividing 1199 by 406, we get 2 with a remainder of 387.
Use 2 as the next digit of our solution. 
Result so far: 11992.0
Deduct 812 from 1199 and we're left with 387.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3870, and continue the process.

Advancing to step 8:
When dividing 3870 by 406, we get 9 with a remainder of 216.
Put 9 as the next digit of the answer. 
Result so far: 11992.9
Subtract 3654 from 3870 to get 216.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2160, and continue the process.

On to step 9:
The number 406 fits into 2160 5 times, leaving a remainder of 130.
Write down 5 as next digit of the result. 
Result so far: 11992.95
If we subtract 2030 from 2160, we get 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

Step 10:
406 can be fit into 1300 3 times, resulting in a remainder of 82.
Put 3 as the next digit of the answer. 
Result so far: 11992.953
Subtract 1218 from 1300 to get 82.
Since there are no more digits in the dividend, we add a zero to the remainder making it 820, and continue the process.

On to step 11:
820 divided by 406 is 2 with a remainder of 8.
Put 2 as the next digit of the answer. 
Result so far: 11992.9532
The remainder is 8 after subtracting 812 from 820.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Going ahead to step 12:
406 goes into 80 0 times with a remainder of 80.
The number 0 becomes the next digit in our result. 
Result so far: 11992.9532
Deduct 0 from 80 and we're left with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Step 13:
800 divided by 406 is 1 with a remainder of 394.
Write down 1 as next digit of the result. 
Result so far: 11992.953201
The remainder is 394 after subtracting 406 from 800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3940, and continue the process.

Let's proceed to step 14:
When dividing 3940 by 406, we get 9 with a remainder of 286.
Write down 9 as next digit of the result. 
Result so far: 11992.9532019
The remainder is 286 after subtracting 3654 from 3940.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2860, and continue the process.

Going ahead to step 15:
406 can be fit into 2860 7 times, resulting in a remainder of 18.
Record the quotient 7 as the next digit in the result. 
Result so far: 11992.95320197
Subtracting 2842 from 2860 leaves us with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

After the division, we end up with 11992.95320197 and a remainder of 1.8e-08.
