Let's divide 91780684 by 570
The aim is to understand the frequency of 570 in 91780684.

On to step 1:
When dividing 9 by 570, we get 0 with a remainder of 9.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 9 to get 9.
Bring next digit (1) of the dividend behind the 9 and repeat the process: 91 / 570

On to step 2:
If we divide 91 by 570, we get 0 and a remainder of 91.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 91 after subtracting 0 from 91.
Include the next digit (7) from the dividend after 91, then repeat: 917 / 570

Advancing to step 3:
If we divide 917 by 570, we get 1 and a remainder of 347.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we take 570 away from 917, we end up with 347.
Include the next digit (8) from the dividend after 347, then repeat: 3478 / 570

On to step 4:
When dividing 3478 by 570, we get 6 with a remainder of 58.
Write down 6 as next digit of the result. 
Result so far: 16.0
The remainder is 58 after subtracting 3420 from 3478.
Take the next digit (0) from the dividend and append it to 58, then repeat: 580 / 570

Moving on to step 5:
580 divided by 570 is 1 with a remainder of 10.
The next digit of our result is 1. 
Result so far: 161.0
Deduct 570 from 580 and we're left with 10.
Append the next digit (6) from the dividend to 10 and continue with: 106 / 570

Going ahead to step 6:
The number 570 fits into 106 0 times, leaving a remainder of 106.
Put 0 as the next digit of the answer. 
Result so far: 1610.0
Subtract 0 from 106 to get 106.
Fetch the next digit (8) from the dividend, attach it to 106 and continue: 1068 / 570

Advancing to step 7:
570 can be fit into 1068 1 times, resulting in a remainder of 498.
Write down 1 as next digit of the result. 
Result so far: 16101.0
Subtract 570 from 1068 to get 498.
Fetch the next digit (4) from the dividend, attach it to 498 and continue: 4984 / 570

Going ahead to step 8:
If we divide 4984 by 570, we get 8 and a remainder of 424.
The next digit of our result is 8. 
Result so far: 161018.0
Deduct 4560 from 4984 and we're left with 424.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4240, and continue the process.

Moving on to step 9:
570 can be fit into 4240 7 times, resulting in a remainder of 250.
Record the quotient 7 as the next digit in the result. 
Result so far: 161018.7
Subtract 3990 from 4240 to get 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2500, and continue the process.

Going ahead to step 10:
570 can be fit into 2500 4 times, resulting in a remainder of 220.
Use 4 as the next digit of our solution. 
Result so far: 161018.74
The remainder is 220 after subtracting 2280 from 2500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2200, and continue the process.

Let's proceed to step 11:
2200 divided by 570 is 3 with a remainder of 490.
The next digit of our result is 3. 
Result so far: 161018.743
If we take 1710 away from 2200, we end up with 490.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4900, and continue the process.

Moving on to step 12:
570 can be fit into 4900 8 times, resulting in a remainder of 340.
Use 8 as the next digit of our solution. 
Result so far: 161018.7438
If we take 4560 away from 4900, we end up with 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3400, and continue the process.

Moving on to step 13:
570 goes into 3400 5 times with a remainder of 550.
Use 5 as the next digit of our solution. 
Result so far: 161018.74385
If we subtract 2850 from 3400, we get 550.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5500, and continue the process.

Let's proceed to step 14:
570 goes into 5500 9 times with a remainder of 370.
The number 9 becomes the next digit in our result. 
Result so far: 161018.743859
Deduct 5130 from 5500 and we're left with 370.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3700, and continue the process.

Moving on to step 15:
The number 570 fits into 3700 6 times, leaving a remainder of 280.
Record the quotient 6 as the next digit in the result. 
Result so far: 161018.7438596
If we subtract 3420 from 3700, we get 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

Advancing to step 16:
2800 divided by 570 is 4 with a remainder of 520.
Use 4 as the next digit of our solution. 
Result so far: 161018.74385964
Subtracting 2280 from 2800 leaves us with 520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5200, and continue the process.

Our division results in 161018.74385964 with a remaining 5.2e-07.
