We look at the division of 4209858 by 553 
Let's see how many times 553 fits into 4209858.

Advancing to step 1:
The number 553 fits into 4 0 times, leaving a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Bring next digit (2) of the dividend behind the 4 and repeat the process: 42 / 553

Let's proceed to step 2:
If we divide 42 by 553, we get 0 and a remainder of 42.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 42 and we're left with 42.
Append the next digit (0) from the dividend to 42 and continue with: 420 / 553

Step 3:
553 can be fit into 420 0 times, resulting in a remainder of 420.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 420 and we're left with 420.
Bring next digit (9) of the dividend behind the 420 and repeat the process: 4209 / 553

Moving on to step 4:
553 goes into 4209 7 times with a remainder of 338.
Write down 7 as next digit of the result. 
Result so far: 7.0
If we take 3871 away from 4209, we end up with 338.
Bring next digit (8) of the dividend behind the 338 and repeat the process: 3388 / 553

Going ahead to step 5:
553 can be fit into 3388 6 times, resulting in a remainder of 70.
Write down 6 as next digit of the result. 
Result so far: 76.0
If we take 3318 away from 3388, we end up with 70.
Bring next digit (5) of the dividend behind the 70 and repeat the process: 705 / 553

Going ahead to step 6:
705 divided by 553 is 1 with a remainder of 152.
Put 1 as the next digit of the answer. 
Result so far: 761.0
If we subtract 553 from 705, we get 152.
Take the next digit (8) from the dividend and append it to 152, then repeat: 1528 / 553

Going ahead to step 7:
If we divide 1528 by 553, we get 2 and a remainder of 422.
The next digit of our result is 2. 
Result so far: 7612.0
If we take 1106 away from 1528, we end up with 422.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4220, and continue the process.

On to step 8:
553 can be fit into 4220 7 times, resulting in a remainder of 349.
Put 7 as the next digit of the answer. 
Result so far: 7612.7
If we subtract 3871 from 4220, we get 349.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3490, and continue the process.

Moving on to step 9:
3490 divided by 553 is 6 with a remainder of 172.
The number 6 becomes the next digit in our result. 
Result so far: 7612.76
Subtracting 3318 from 3490 leaves us with 172.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1720, and continue the process.

Step 10:
If we divide 1720 by 553, we get 3 and a remainder of 61.
Use 3 as the next digit of our solution. 
Result so far: 7612.763
If we subtract 1659 from 1720, we get 61.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

Step 11:
The number 553 fits into 610 1 times, leaving a remainder of 57.
Write down 1 as next digit of the result. 
Result so far: 7612.7631
Subtracting 553 from 610 leaves us with 57.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

Let's proceed to step 12:
553 goes into 570 1 times with a remainder of 17.
The next digit of our result is 1. 
Result so far: 7612.76311
Subtract 553 from 570 to get 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

The final result is 7612.76311 with a remainder of 1.7e-05.
