We're dividing 69870671 by 137 
The aim is to understand the frequency of 137 in 69870671.

On to step 1:
6 divided by 137 is 0 with a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Include the next digit (9) from the dividend after 6, then repeat: 69 / 137

Advancing to step 2:
The number 137 fits into 69 0 times, leaving a remainder of 69.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 69 after subtracting 0 from 69.
Bring next digit (8) of the dividend behind the 69 and repeat the process: 698 / 137

On to step 3:
The number 137 fits into 698 5 times, leaving a remainder of 13.
Put 5 as the next digit of the answer. 
Result so far: 5.0
Subtract 685 from 698 to get 13.
Fetch the next digit (7) from the dividend, attach it to 13 and continue: 137 / 137

Step 4:
137 can be fit into 137 1 times, resulting in a remainder of 0.
The number 1 becomes the next digit in our result. 
Result so far: 51.0
Deduct 137 from 137 and we're left with 0.
Grab the next digit (0) from the dividend, add it to 0, then carry on: 0 / 137

Step 5:
The number 137 fits into 0 0 times, leaving a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 510.0
Subtracting 0 from 0 leaves us with 0.
Include the next digit (6) from the dividend after 0, then repeat: 6 / 137

Going ahead to step 6:
When dividing 6 by 137, we get 0 with a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 5100.0
Subtract 0 from 6 to get 6.
Grab the next digit (7) from the dividend, add it to 6, then carry on: 67 / 137

Step 7:
137 can be fit into 67 0 times, resulting in a remainder of 67.
The number 0 becomes the next digit in our result. 
Result so far: 51000.0
Subtracting 0 from 67 leaves us with 67.
Take the next digit (1) from the dividend and append it to 67, then repeat: 671 / 137

Moving on to step 8:
137 can be fit into 671 4 times, resulting in a remainder of 123.
Write down 4 as next digit of the result. 
Result so far: 510004.0
Subtract 548 from 671 to get 123.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1230, and continue the process.

Step 9:
137 goes into 1230 8 times with a remainder of 134.
Record the quotient 8 as the next digit in the result. 
Result so far: 510004.8
Subtract 1096 from 1230 to get 134.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1340, and continue the process.

Step 10:
If we divide 1340 by 137, we get 9 and a remainder of 107.
Put 9 as the next digit of the answer. 
Result so far: 510004.89
Deduct 1233 from 1340 and we're left with 107.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1070, and continue the process.

Let's proceed to step 11:
If we divide 1070 by 137, we get 7 and a remainder of 111.
Use 7 as the next digit of our solution. 
Result so far: 510004.897
Deduct 959 from 1070 and we're left with 111.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1110, and continue the process.

Moving on to step 12:
The number 137 fits into 1110 8 times, leaving a remainder of 14.
The next digit of our result is 8. 
Result so far: 510004.8978
The remainder is 14 after subtracting 1096 from 1110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Step 13:
137 goes into 140 1 times with a remainder of 3.
The number 1 becomes the next digit in our result. 
Result so far: 510004.89781
Deduct 137 from 140 and we're left with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Advancing to step 14:
The number 137 fits into 30 0 times, leaving a remainder of 30.
The next digit of our result is 0. 
Result so far: 510004.89781
Subtracting 0 from 30 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 15:
137 can be fit into 300 2 times, resulting in a remainder of 26.
Write down 2 as next digit of the result. 
Result so far: 510004.8978102
If we take 274 away from 300, we end up with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Advancing to step 16:
137 can be fit into 260 1 times, resulting in a remainder of 123.
Write down 1 as next digit of the result. 
Result so far: 510004.89781021
Subtract 137 from 260 to get 123.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1230, and continue the process.

After the division, we end up with 510004.89781021 and a remainder of 1.23e-07.
