53002569 ÷ 170 
The aim is to understand the frequency of 170 in 53002569.

Let's proceed to step 1:
170 goes into 5 0 times with a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Take the next digit (3) from the dividend and append it to 5, then repeat: 53 / 170

Going ahead to step 2:
When dividing 53 by 170, we get 0 with a remainder of 53.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 53 and we're left with 53.
Grab the next digit (0) from the dividend, add it to 53, then carry on: 530 / 170

Step 3:
If we divide 530 by 170, we get 3 and a remainder of 20.
Write down 3 as next digit of the result. 
Result so far: 3.0
If we take 510 away from 530, we end up with 20.
Bring next digit (0) of the dividend behind the 20 and repeat the process: 200 / 170

On to step 4:
170 can be fit into 200 1 times, resulting in a remainder of 30.
Record the quotient 1 as the next digit in the result. 
Result so far: 31.0
Subtract 170 from 200 to get 30.
Bring next digit (2) of the dividend behind the 30 and repeat the process: 302 / 170

On to step 5:
If we divide 302 by 170, we get 1 and a remainder of 132.
Use 1 as the next digit of our solution. 
Result so far: 311.0
The remainder is 132 after subtracting 170 from 302.
Take the next digit (5) from the dividend and append it to 132, then repeat: 1325 / 170

On to step 6:
170 can be fit into 1325 7 times, resulting in a remainder of 135.
The next digit of our result is 7. 
Result so far: 3117.0
If we subtract 1190 from 1325, we get 135.
Take the next digit (6) from the dividend and append it to 135, then repeat: 1356 / 170

Let's proceed to step 7:
When dividing 1356 by 170, we get 7 with a remainder of 166.
The number 7 becomes the next digit in our result. 
Result so far: 31177.0
If we take 1190 away from 1356, we end up with 166.
Append the next digit (9) from the dividend to 166 and continue with: 1669 / 170

On to step 8:
1669 divided by 170 is 9 with a remainder of 139.
Write down 9 as next digit of the result. 
Result so far: 311779.0
If we take 1530 away from 1669, we end up with 139.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1390, and continue the process.

Step 9:
If we divide 1390 by 170, we get 8 and a remainder of 30.
Use 8 as the next digit of our solution. 
Result so far: 311779.8
Subtracting 1360 from 1390 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.

Let's proceed to step 10:
170 can be fit into 300 1 times, resulting in a remainder of 130.
The number 1 becomes the next digit in our result. 
Result so far: 311779.81
Subtract 170 from 300 to get 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

Moving on to step 11:
170 goes into 1300 7 times with a remainder of 110.
Put 7 as the next digit of the answer. 
Result so far: 311779.817
If we take 1190 away from 1300, we end up with 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1100, and continue the process.

Moving on to step 12:
The number 170 fits into 1100 6 times, leaving a remainder of 80.
Write down 6 as next digit of the result. 
Result so far: 311779.8176
Subtract 1020 from 1100 to get 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Advancing to step 13:
170 goes into 800 4 times with a remainder of 120.
Use 4 as the next digit of our solution. 
Result so far: 311779.81764
Subtract 680 from 800 to get 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Going ahead to step 14:
The number 170 fits into 1200 7 times, leaving a remainder of 10.
The number 7 becomes the next digit in our result. 
Result so far: 311779.817647
If we subtract 1190 from 1200, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Let's proceed to step 15:
If we divide 100 by 170, we get 0 and a remainder of 100.
Use 0 as the next digit of our solution. 
Result so far: 311779.817647
The remainder is 100 after subtracting 0 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Advancing to step 16:
The number 170 fits into 1000 5 times, leaving a remainder of 150.
Record the quotient 5 as the next digit in the result. 
Result so far: 311779.81764705
If we subtract 850 from 1000, we 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.

The final outcome is 311779.81764705, with a leftover of 1.5e-07.
