We divide 66720353 by 607
The aim is to understand the frequency of 607 in 66720353.

Step 1:
6 divided by 607 is 0 with a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Fetch the next digit (6) from the dividend, attach it to 6 and continue: 66 / 607

On to step 2:
66 divided by 607 is 0 with a remainder of 66.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 66, we end up with 66.
Append the next digit (7) from the dividend to 66 and continue with: 667 / 607

Moving on to step 3:
The number 607 fits into 667 1 times, leaving a remainder of 60.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtracting 607 from 667 leaves us with 60.
Bring next digit (2) of the dividend behind the 60 and repeat the process: 602 / 607

Advancing to step 4:
If we divide 602 by 607, we get 0 and a remainder of 602.
Write down 0 as next digit of the result. 
Result so far: 10.0
Subtract 0 from 602 to get 602.
Grab the next digit (0) from the dividend, add it to 602, then carry on: 6020 / 607

Going ahead to step 5:
When dividing 6020 by 607, we get 9 with a remainder of 557.
Put 9 as the next digit of the answer. 
Result so far: 109.0
If we take 5463 away from 6020, we end up with 557.
Fetch the next digit (3) from the dividend, attach it to 557 and continue: 5573 / 607

On to step 6:
The number 607 fits into 5573 9 times, leaving a remainder of 110.
Use 9 as the next digit of our solution. 
Result so far: 1099.0
If we subtract 5463 from 5573, we get 110.
Take the next digit (5) from the dividend and append it to 110, then repeat: 1105 / 607

Let's proceed to step 7:
When dividing 1105 by 607, we get 1 with a remainder of 498.
Use 1 as the next digit of our solution. 
Result so far: 10991.0
If we subtract 607 from 1105, we get 498.
Append the next digit (3) from the dividend to 498 and continue with: 4983 / 607

Advancing to step 8:
4983 divided by 607 is 8 with a remainder of 127.
Record the quotient 8 as the next digit in the result. 
Result so far: 109918.0
Subtract 4856 from 4983 to get 127.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1270, and continue the process.

Going ahead to step 9:
The number 607 fits into 1270 2 times, leaving a remainder of 56.
Use 2 as the next digit of our solution. 
Result so far: 109918.2
If we subtract 1214 from 1270, we get 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Going ahead to step 10:
560 divided by 607 is 0 with a remainder of 560.
The number 0 becomes the next digit in our result. 
Result so far: 109918.2
The remainder is 560 after subtracting 0 from 560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5600, and continue the process.

Going ahead to step 11:
The number 607 fits into 5600 9 times, leaving a remainder of 137.
Write down 9 as next digit of the result. 
Result so far: 109918.209
The remainder is 137 after subtracting 5463 from 5600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1370, and continue the process.

Going ahead to step 12:
1370 divided by 607 is 2 with a remainder of 156.
The next digit of our result is 2. 
Result so far: 109918.2092
Subtracting 1214 from 1370 leaves us with 156.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1560, and continue the process.

Advancing to step 13:
607 goes into 1560 2 times with a remainder of 346.
The next digit of our result is 2. 
Result so far: 109918.20922
Deduct 1214 from 1560 and we're left with 346.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3460, and continue the process.

Our division results in 109918.20922 with a remaining 0.000346.
