We're dividing 70372146 by 570 
The aim is to understand the frequency of 570 in 70372146.

On to step 1:
When dividing 7 by 570, we get 0 with a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Append the next digit (0) from the dividend to 7 and continue with: 70 / 570

Advancing to step 2:
When dividing 70 by 570, we get 0 with a remainder of 70.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 70 and we're left with 70.
Take the next digit (3) from the dividend and append it to 70, then repeat: 703 / 570

Advancing to step 3:
703 divided by 570 is 1 with a remainder of 133.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Deduct 570 from 703 and we're left with 133.
Append the next digit (7) from the dividend to 133 and continue with: 1337 / 570

Moving on to step 4:
570 can be fit into 1337 2 times, resulting in a remainder of 197.
Use 2 as the next digit of our solution. 
Result so far: 12.0
The remainder is 197 after subtracting 1140 from 1337.
Include the next digit (2) from the dividend after 197, then repeat: 1972 / 570

Let's proceed to step 5:
When dividing 1972 by 570, we get 3 with a remainder of 262.
Write down 3 as next digit of the result. 
Result so far: 123.0
Subtract 1710 from 1972 to get 262.
Include the next digit (1) from the dividend after 262, then repeat: 2621 / 570

Going ahead to step 6:
570 can be fit into 2621 4 times, resulting in a remainder of 341.
Record the quotient 4 as the next digit in the result. 
Result so far: 1234.0
The remainder is 341 after subtracting 2280 from 2621.
Grab the next digit (4) from the dividend, add it to 341, then carry on: 3414 / 570

Advancing to step 7:
The number 570 fits into 3414 5 times, leaving a remainder of 564.
Put 5 as the next digit of the answer. 
Result so far: 12345.0
The remainder is 564 after subtracting 2850 from 3414.
Bring next digit (6) of the dividend behind the 564 and repeat the process: 5646 / 570

On to step 8:
When dividing 5646 by 570, we get 9 with a remainder of 516.
The number 9 becomes the next digit in our result. 
Result so far: 123459.0
Subtracting 5130 from 5646 leaves us with 516.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5160, and continue the process.

Going ahead to step 9:
5160 divided by 570 is 9 with a remainder of 30.
Put 9 as the next digit of the answer. 
Result so far: 123459.9
Subtracting 5130 from 5160 leaves us with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

On to step 10:
When dividing 300 by 570, we get 0 with a remainder of 300.
Use 0 as the next digit of our solution. 
Result so far: 123459.9
Subtracting 0 from 300 leaves us with 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

Advancing to step 11:
If we divide 3000 by 570, we get 5 and a remainder of 150.
The next digit of our result is 5. 
Result so far: 123459.905
Subtract 2850 from 3000 to get 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

Let's proceed to step 12:
The number 570 fits into 1500 2 times, leaving a remainder of 360.
Use 2 as the next digit of our solution. 
Result so far: 123459.9052
If we subtract 1140 from 1500, we get 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3600, and continue the process.

Moving on to step 13:
570 can be fit into 3600 6 times, resulting in a remainder of 180.
Put 6 as the next digit of the answer. 
Result so far: 123459.90526
If we subtract 3420 from 3600, we get 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

Let's proceed to step 14:
When dividing 1800 by 570, we get 3 with a remainder of 90.
The number 3 becomes the next digit in our result. 
Result so far: 123459.905263
Subtracting 1710 from 1800 leaves us with 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

On to step 15:
The number 570 fits into 900 1 times, leaving a remainder of 330.
Put 1 as the next digit of the answer. 
Result so far: 123459.9052631
Deduct 570 from 900 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.

Step 16:
3300 divided by 570 is 5 with a remainder of 450.
Use 5 as the next digit of our solution. 
Result so far: 123459.90526315
The remainder is 450 after subtracting 2850 from 3300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4500, and continue the process.

After the division, we end up with 123459.90526315 and a remainder of 4.5e-07.
