We're dividing 2907345 by 137 
The aim is to understand the frequency of 137 in 2907345.

On to step 1:
2 divided by 137 is 0 with a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Include the next digit (9) from the dividend after 2, then repeat: 29 / 137

Moving on to step 2:
137 can be fit into 29 0 times, resulting in a remainder of 29.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 29 leaves us with 29.
Include the next digit (0) from the dividend after 29, then repeat: 290 / 137

Let's proceed to step 3:
When dividing 290 by 137, we get 2 with a remainder of 16.
Put 2 as the next digit of the answer. 
Result so far: 2.0
Subtract 274 from 290 to get 16.
Take the next digit (7) from the dividend and append it to 16, then repeat: 167 / 137

Let's proceed to step 4:
When dividing 167 by 137, we get 1 with a remainder of 30.
Record the quotient 1 as the next digit in the result. 
Result so far: 21.0
If we subtract 137 from 167, we get 30.
Grab the next digit (3) from the dividend, add it to 30, then carry on: 303 / 137

Advancing to step 5:
137 can be fit into 303 2 times, resulting in a remainder of 29.
Write down 2 as next digit of the result. 
Result so far: 212.0
If we subtract 274 from 303, we get 29.
Bring next digit (4) of the dividend behind the 29 and repeat the process: 294 / 137

Step 6:
The number 137 fits into 294 2 times, leaving a remainder of 20.
The number 2 becomes the next digit in our result. 
Result so far: 2122.0
Deduct 274 from 294 and we're left with 20.
Append the next digit (5) from the dividend to 20 and continue with: 205 / 137

On to step 7:
205 divided by 137 is 1 with a remainder of 68.
Record the quotient 1 as the next digit in the result. 
Result so far: 21221.0
If we take 137 away from 205, we end up with 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

On to step 8:
680 divided by 137 is 4 with a remainder of 132.
Record the quotient 4 as the next digit in the result. 
Result so far: 21221.4
Deduct 548 from 680 and we're left with 132.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1320, and continue the process.

Going ahead to step 9:
137 can be fit into 1320 9 times, resulting in a remainder of 87.
Use 9 as the next digit of our solution. 
Result so far: 21221.49
If we subtract 1233 from 1320, we get 87.
Since there are no more digits in the dividend, we add a zero to the remainder making it 870, and continue the process.

Let's proceed to step 10:
137 goes into 870 6 times with a remainder of 48.
The next digit of our result is 6. 
Result so far: 21221.496
Subtracting 822 from 870 leaves us with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Advancing to step 11:
480 divided by 137 is 3 with a remainder of 69.
Put 3 as the next digit of the answer. 
Result so far: 21221.4963
If we take 411 away from 480, we end up with 69.
Since there are no more digits in the dividend, we add a zero to the remainder making it 690, and continue the process.

On to step 12:
When dividing 690 by 137, we get 5 with a remainder of 5.
Write down 5 as next digit of the result. 
Result so far: 21221.49635
The remainder is 5 after subtracting 685 from 690.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Going ahead to step 13:
If we divide 50 by 137, we get 0 and a remainder of 50.
The next digit of our result is 0. 
Result so far: 21221.49635
Deduct 0 from 50 and we're left with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Going ahead to step 14:
If we divide 500 by 137, we get 3 and a remainder of 89.
Use 3 as the next digit of our solution. 
Result so far: 21221.4963503
Subtracting 411 from 500 leaves us with 89.
Since there are no more digits in the dividend, we add a zero to the remainder making it 890, and continue the process.

Going ahead to step 15:
The number 137 fits into 890 6 times, leaving a remainder of 68.
Use 6 as the next digit of our solution. 
Result so far: 21221.49635036
If we take 822 away from 890, we end up with 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

The final outcome is 21221.49635036, with a leftover of 6.8e-08.
