We look at the division of 31668344 by 607 
The aim is to understand the frequency of 607 in 31668344.

Advancing to step 1:
607 can be fit into 3 0 times, resulting in a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Bring next digit (1) of the dividend behind the 3 and repeat the process: 31 / 607

Step 2:
When dividing 31 by 607, we get 0 with a remainder of 31.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 31 to get 31.
Fetch the next digit (6) from the dividend, attach it to 31 and continue: 316 / 607

Moving on to step 3:
When dividing 316 by 607, we get 0 with a remainder of 316.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 316 leaves us with 316.
Include the next digit (6) from the dividend after 316, then repeat: 3166 / 607

Step 4:
When dividing 3166 by 607, we get 5 with a remainder of 131.
Put 5 as the next digit of the answer. 
Result so far: 5.0
Subtracting 3035 from 3166 leaves us with 131.
Fetch the next digit (8) from the dividend, attach it to 131 and continue: 1318 / 607

Moving on to step 5:
607 can be fit into 1318 2 times, resulting in a remainder of 104.
Use 2 as the next digit of our solution. 
Result so far: 52.0
Deduct 1214 from 1318 and we're left with 104.
Include the next digit (3) from the dividend after 104, then repeat: 1043 / 607

Let's proceed to step 6:
The number 607 fits into 1043 1 times, leaving a remainder of 436.
The next digit of our result is 1. 
Result so far: 521.0
Deduct 607 from 1043 and we're left with 436.
Grab the next digit (4) from the dividend, add it to 436, then carry on: 4364 / 607

Going ahead to step 7:
4364 divided by 607 is 7 with a remainder of 115.
Write down 7 as next digit of the result. 
Result so far: 5217.0
Subtracting 4249 from 4364 leaves us with 115.
Append the next digit (4) from the dividend to 115 and continue with: 1154 / 607

Let's proceed to step 8:
607 can be fit into 1154 1 times, resulting in a remainder of 547.
Put 1 as the next digit of the answer. 
Result so far: 52171.0
Subtract 607 from 1154 to get 547.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5470, and continue the process.

Let's proceed to step 9:
If we divide 5470 by 607, we get 9 and a remainder of 7.
The next digit of our result is 9. 
Result so far: 52171.9
Deduct 5463 from 5470 and we're left with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Let's proceed to step 10:
The number 607 fits into 70 0 times, leaving a remainder of 70.
Write down 0 as next digit of the result. 
Result so far: 52171.9
Subtract 0 from 70 to get 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

On to step 11:
When dividing 700 by 607, we get 1 with a remainder of 93.
Use 1 as the next digit of our solution. 
Result so far: 52171.901
Subtracting 607 from 700 leaves us with 93.
Since there are no more digits in the dividend, we add a zero to the remainder making it 930, and continue the process.

Advancing to step 12:
The number 607 fits into 930 1 times, leaving a remainder of 323.
The number 1 becomes the next digit in our result. 
Result so far: 52171.9011
Subtract 607 from 930 to get 323.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3230, and continue the process.

The final result is 52171.9011 with a remainder of 0.00323.
