3991572 ÷ 570 
We want to figure out the number of times 3991572 can be divided by 570.

Moving on to step 1:
570 goes into 3 0 times with a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Append the next digit (9) from the dividend to 3 and continue with: 39 / 570

Let's proceed to step 2:
570 goes into 39 0 times with a remainder of 39.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 39, we get 39.
Append the next digit (9) from the dividend to 39 and continue with: 399 / 570

Advancing to step 3:
If we divide 399 by 570, we get 0 and a remainder of 399.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 399, we get 399.
Bring next digit (1) of the dividend behind the 399 and repeat the process: 3991 / 570

Step 4:
570 goes into 3991 7 times with a remainder of 1.
The next digit of our result is 7. 
Result so far: 7.0
If we subtract 3990 from 3991, we get 1.
Append the next digit (5) from the dividend to 1 and continue with: 15 / 570

Moving on to step 5:
15 divided by 570 is 0 with a remainder of 15.
Write down 0 as next digit of the result. 
Result so far: 70.0
Subtracting 0 from 15 leaves us with 15.
Append the next digit (7) from the dividend to 15 and continue with: 157 / 570

Step 6:
If we divide 157 by 570, we get 0 and a remainder of 157.
Record the quotient 0 as the next digit in the result. 
Result so far: 700.0
Deduct 0 from 157 and we're left with 157.
Append the next digit (2) from the dividend to 157 and continue with: 1572 / 570

Let's proceed to step 7:
1572 divided by 570 is 2 with a remainder of 432.
Record the quotient 2 as the next digit in the result. 
Result so far: 7002.0
Subtract 1140 from 1572 to get 432.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4320, and continue the process.

Advancing to step 8:
570 goes into 4320 7 times with a remainder of 330.
Put 7 as the next digit of the answer. 
Result so far: 7002.7
Deduct 3990 from 4320 and we're left with 330.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3300, and continue the process.

Moving on to step 9:
If we divide 3300 by 570, we get 5 and a remainder of 450.
Put 5 as the next digit of the answer. 
Result so far: 7002.75
Subtract 2850 from 3300 to get 450.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4500, and continue the process.

Advancing to step 10:
570 goes into 4500 7 times with a remainder of 510.
The number 7 becomes the next digit in our result. 
Result so far: 7002.757
The remainder is 510 after subtracting 3990 from 4500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5100, and continue the process.

Going ahead to step 11:
570 can be fit into 5100 8 times, resulting in a remainder of 540.
Write down 8 as next digit of the result. 
Result so far: 7002.7578
Subtract 4560 from 5100 to get 540.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5400, and continue the process.

Advancing to step 12:
570 goes into 5400 9 times with a remainder of 270.
Record the quotient 9 as the next digit in the result. 
Result so far: 7002.75789
If we take 5130 away from 5400, we end up with 270.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2700, and continue the process.

On to step 13:
570 can be fit into 2700 4 times, resulting in a remainder of 420.
Record the quotient 4 as the next digit in the result. 
Result so far: 7002.757894
Deduct 2280 from 2700 and we're left with 420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4200, and continue the process.

Step 14:
When dividing 4200 by 570, we get 7 with a remainder of 210.
Record the quotient 7 as the next digit in the result. 
Result so far: 7002.7578947
Deduct 3990 from 4200 and we're left with 210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2100, and continue the process.

Advancing to step 15:
570 can be fit into 2100 3 times, resulting in a remainder of 390.
The number 3 becomes the next digit in our result. 
Result so far: 7002.75789473
Deduct 1710 from 2100 and we're left with 390.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3900, and continue the process.

After the division, we end up with 7002.75789473 and a remainder of 3.9e-07.
