We're dividing 4220957 by 570 
We want to divide 4220957 by 570.

Step 1:
4 divided by 570 is 0 with a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Take the next digit (2) from the dividend and append it to 4, then repeat: 42 / 570

Going ahead to step 2:
570 goes into 42 0 times with a remainder of 42.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 42 leaves us with 42.
Take the next digit (2) from the dividend and append it to 42, then repeat: 422 / 570

Moving on to step 3:
570 can be fit into 422 0 times, resulting in a remainder of 422.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 422 after subtracting 0 from 422.
Bring next digit (0) of the dividend behind the 422 and repeat the process: 4220 / 570

Let's proceed to step 4:
When dividing 4220 by 570, we get 7 with a remainder of 230.
Put 7 as the next digit of the answer. 
Result so far: 7.0
If we take 3990 away from 4220, we end up with 230.
Grab the next digit (9) from the dividend, add it to 230, then carry on: 2309 / 570

Step 5:
The number 570 fits into 2309 4 times, leaving a remainder of 29.
The number 4 becomes the next digit in our result. 
Result so far: 74.0
The remainder is 29 after subtracting 2280 from 2309.
Append the next digit (5) from the dividend to 29 and continue with: 295 / 570

On to step 6:
If we divide 295 by 570, we get 0 and a remainder of 295.
Put 0 as the next digit of the answer. 
Result so far: 740.0
If we subtract 0 from 295, we get 295.
Fetch the next digit (7) from the dividend, attach it to 295 and continue: 2957 / 570

On to step 7:
2957 divided by 570 is 5 with a remainder of 107.
Write down 5 as next digit of the result. 
Result so far: 7405.0
Deduct 2850 from 2957 and we're left with 107.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1070, and continue the process.

Let's proceed to step 8:
If we divide 1070 by 570, we get 1 and a remainder of 500.
Record the quotient 1 as the next digit in the result. 
Result so far: 7405.1
Deduct 570 from 1070 and we're left with 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5000, and continue the process.

Let's proceed to step 9:
570 goes into 5000 8 times with a remainder of 440.
The next digit of our result is 8. 
Result so far: 7405.18
The remainder is 440 after subtracting 4560 from 5000.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4400, and continue the process.

On to step 10:
570 goes into 4400 7 times with a remainder of 410.
The next digit of our result is 7. 
Result so far: 7405.187
The remainder is 410 after subtracting 3990 from 4400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4100, and continue the process.

Moving on to step 11:
570 goes into 4100 7 times with a remainder of 110.
Put 7 as the next digit of the answer. 
Result so far: 7405.1877
If we subtract 3990 from 4100, we get 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1100, and continue the process.

The final result is 7405.1877 with a remainder of 0.0011.
