69725531 ÷ 137 
The aim is to understand the frequency of 137 in 69725531.

Let's proceed to step 1:
137 goes into 6 0 times with a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Take the next digit (9) from the dividend and append it to 6, then repeat: 69 / 137

Going ahead to step 2:
The number 137 fits into 69 0 times, leaving a remainder of 69.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 69 and we're left with 69.
Include the next digit (7) from the dividend after 69, then repeat: 697 / 137

On to step 3:
697 divided by 137 is 5 with a remainder of 12.
Use 5 as the next digit of our solution. 
Result so far: 5.0
If we take 685 away from 697, we end up with 12.
Append the next digit (2) from the dividend to 12 and continue with: 122 / 137

Step 4:
The number 137 fits into 122 0 times, leaving a remainder of 122.
Use 0 as the next digit of our solution. 
Result so far: 50.0
Subtract 0 from 122 to get 122.
Take the next digit (5) from the dividend and append it to 122, then repeat: 1225 / 137

Going ahead to step 5:
The number 137 fits into 1225 8 times, leaving a remainder of 129.
Record the quotient 8 as the next digit in the result. 
Result so far: 508.0
If we take 1096 away from 1225, we end up with 129.
Bring next digit (5) of the dividend behind the 129 and repeat the process: 1295 / 137

Moving on to step 6:
The number 137 fits into 1295 9 times, leaving a remainder of 62.
Use 9 as the next digit of our solution. 
Result so far: 5089.0
Subtracting 1233 from 1295 leaves us with 62.
Include the next digit (3) from the dividend after 62, then repeat: 623 / 137

Let's proceed to step 7:
The number 137 fits into 623 4 times, leaving a remainder of 75.
Record the quotient 4 as the next digit in the result. 
Result so far: 50894.0
Deduct 548 from 623 and we're left with 75.
Include the next digit (1) from the dividend after 75, then repeat: 751 / 137

On to step 8:
If we divide 751 by 137, we get 5 and a remainder of 66.
The next digit of our result is 5. 
Result so far: 508945.0
Subtract 685 from 751 to get 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

On to step 9:
137 goes into 660 4 times with a remainder of 112.
Put 4 as the next digit of the answer. 
Result so far: 508945.4
Deduct 548 from 660 and we're left with 112.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1120, and continue the process.

On to step 10:
137 can be fit into 1120 8 times, resulting in a remainder of 24.
The number 8 becomes the next digit in our result. 
Result so far: 508945.48
If we take 1096 away from 1120, we end up with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Step 11:
If we divide 240 by 137, we get 1 and a remainder of 103.
The number 1 becomes the next digit in our result. 
Result so far: 508945.481
Subtracting 137 from 240 leaves us with 103.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1030, and continue the process.

Step 12:
If we divide 1030 by 137, we get 7 and a remainder of 71.
Write down 7 as next digit of the result. 
Result so far: 508945.4817
If we take 959 away from 1030, we end up with 71.
Since there are no more digits in the dividend, we add a zero to the remainder making it 710, and continue the process.

On to step 13:
710 divided by 137 is 5 with a remainder of 25.
The number 5 becomes the next digit in our result. 
Result so far: 508945.48175
Deduct 685 from 710 and we're left with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Going ahead to step 14:
137 can be fit into 250 1 times, resulting in a remainder of 113.
Use 1 as the next digit of our solution. 
Result so far: 508945.481751
Deduct 137 from 250 and we're left with 113.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1130, and continue the process.

Let's proceed to step 15:
If we divide 1130 by 137, we get 8 and a remainder of 34.
The number 8 becomes the next digit in our result. 
Result so far: 508945.4817518
The remainder is 34 after subtracting 1096 from 1130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Advancing to step 16:
137 goes into 340 2 times with a remainder of 66.
Use 2 as the next digit of our solution. 
Result so far: 508945.48175182
If we subtract 274 from 340, we get 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

After the division, we end up with 508945.48175182 and a remainder of 6.6e-08.
