79420160 ÷ 570 
The aim is to understand the frequency of 570 in 79420160.

On to step 1:
570 goes into 7 0 times with a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Fetch the next digit (9) from the dividend, attach it to 7 and continue: 79 / 570

Let's proceed to step 2:
When dividing 79 by 570, we get 0 with a remainder of 79.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 79 leaves us with 79.
Fetch the next digit (4) from the dividend, attach it to 79 and continue: 794 / 570

Step 3:
If we divide 794 by 570, we get 1 and a remainder of 224.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Deduct 570 from 794 and we're left with 224.
Grab the next digit (2) from the dividend, add it to 224, then carry on: 2242 / 570

Advancing to step 4:
570 goes into 2242 3 times with a remainder of 532.
Use 3 as the next digit of our solution. 
Result so far: 13.0
The remainder is 532 after subtracting 1710 from 2242.
Bring next digit (0) of the dividend behind the 532 and repeat the process: 5320 / 570

Let's proceed to step 5:
5320 divided by 570 is 9 with a remainder of 190.
Use 9 as the next digit of our solution. 
Result so far: 139.0
Subtract 5130 from 5320 to get 190.
Take the next digit (1) from the dividend and append it to 190, then repeat: 1901 / 570

Moving on to step 6:
570 goes into 1901 3 times with a remainder of 191.
Put 3 as the next digit of the answer. 
Result so far: 1393.0
The remainder is 191 after subtracting 1710 from 1901.
Append the next digit (6) from the dividend to 191 and continue with: 1916 / 570

Going ahead to step 7:
If we divide 1916 by 570, we get 3 and a remainder of 206.
Put 3 as the next digit of the answer. 
Result so far: 13933.0
The remainder is 206 after subtracting 1710 from 1916.
Fetch the next digit (0) from the dividend, attach it to 206 and continue: 2060 / 570

Advancing to step 8:
570 can be fit into 2060 3 times, resulting in a remainder of 350.
The next digit of our result is 3. 
Result so far: 139333.0
Subtract 1710 from 2060 to get 350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3500, and continue the process.

Advancing to step 9:
When dividing 3500 by 570, we get 6 with a remainder of 80.
Use 6 as the next digit of our solution. 
Result so far: 139333.6
Subtracting 3420 from 3500 leaves us 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 10:
570 can be fit into 800 1 times, resulting in a remainder of 230.
Use 1 as the next digit of our solution. 
Result so far: 139333.61
If we take 570 away from 800, we end up with 230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2300, and continue the process.

Step 11:
570 goes into 2300 4 times with a remainder of 20.
Record the quotient 4 as the next digit in the result. 
Result so far: 139333.614
If we subtract 2280 from 2300, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Going ahead to step 12:
The number 570 fits into 200 0 times, leaving a remainder of 200.
Put 0 as the next digit of the answer. 
Result so far: 139333.614
The remainder is 200 after subtracting 0 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

Let's proceed to step 13:
2000 divided by 570 is 3 with a remainder of 290.
Write down 3 as next digit of the result. 
Result so far: 139333.61403
Deduct 1710 from 2000 and we're left with 290.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2900, and continue the process.

Let's proceed to step 14:
570 goes into 2900 5 times with a remainder of 50.
The number 5 becomes the next digit in our result. 
Result so far: 139333.614035
If we take 2850 away from 2900, we end up with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Step 15:
The number 570 fits into 500 0 times, leaving a remainder of 500.
The next digit of our result is 0. 
Result so far: 139333.614035
If we take 0 away from 500, we end up 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.

On to step 16:
570 goes into 5000 8 times with a remainder of 440.
The number 8 becomes the next digit in our result. 
Result so far: 139333.61403508
Deduct 4560 from 5000 and we're left with 440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4400, and continue the process.

The quotient of the division is 139333.61403508, and the remainder is 4.4e-07.
