We look at the division of 31413290 by 607 
The aim is to understand the frequency of 607 in 31413290.

Advancing to step 1:
The number 607 fits into 3 0 times, leaving a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Append the next digit (1) from the dividend to 3 and continue with: 31 / 607

Advancing to step 2:
When dividing 31 by 607, we get 0 with a remainder of 31.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 31 leaves us with 31.
Grab the next digit (4) from the dividend, add it to 31, then carry on: 314 / 607

On to step 3:
The number 607 fits into 314 0 times, leaving a remainder of 314.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 314 leaves us with 314.
Include the next digit (1) from the dividend after 314, then repeat: 3141 / 607

Step 4:
If we divide 3141 by 607, we get 5 and a remainder of 106.
The next digit of our result is 5. 
Result so far: 5.0
Subtracting 3035 from 3141 leaves us with 106.
Append the next digit (3) from the dividend to 106 and continue with: 1063 / 607

Let's proceed to step 5:
607 can be fit into 1063 1 times, resulting in a remainder of 456.
Record the quotient 1 as the next digit in the result. 
Result so far: 51.0
Deduct 607 from 1063 and we're left with 456.
Grab the next digit (2) from the dividend, add it to 456, then carry on: 4562 / 607

Advancing to step 6:
The number 607 fits into 4562 7 times, leaving a remainder of 313.
Put 7 as the next digit of the answer. 
Result so far: 517.0
Subtract 4249 from 4562 to get 313.
Take the next digit (9) from the dividend and append it to 313, then repeat: 3139 / 607

Step 7:
When dividing 3139 by 607, we get 5 with a remainder of 104.
The number 5 becomes the next digit in our result. 
Result so far: 5175.0
Deduct 3035 from 3139 and we're left with 104.
Take the next digit (0) from the dividend and append it to 104, then repeat: 1040 / 607

On to step 8:
If we divide 1040 by 607, we get 1 and a remainder of 433.
Put 1 as the next digit of the answer. 
Result so far: 51751.0
Deduct 607 from 1040 and we're left with 433.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4330, and continue the process.

On to step 9:
607 can be fit into 4330 7 times, resulting in a remainder of 81.
Put 7 as the next digit of the answer. 
Result so far: 51751.7
If we subtract 4249 from 4330, we get 81.
Since there are no more digits in the dividend, we add a zero to the remainder making it 810, and continue the process.

Let's proceed to step 10:
607 can be fit into 810 1 times, resulting in a remainder of 203.
Use 1 as the next digit of our solution. 
Result so far: 51751.71
Deduct 607 from 810 and we're left with 203.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2030, and continue the process.

Let's proceed to step 11:
2030 divided by 607 is 3 with a remainder of 209.
The next digit of our result is 3. 
Result so far: 51751.713
If we take 1821 away from 2030, we end up with 209.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2090, and continue the process.

On to step 12:
2090 divided by 607 is 3 with a remainder of 269.
The next digit of our result is 3. 
Result so far: 51751.7133
Deduct 1821 from 2090 and we're left with 269.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2690, and continue the process.

After the division, we end up with 51751.7133 and a remainder of 0.00269.
