52606797 ÷ 407 
The aim is to understand the frequency of 407 in 52606797.

Let's proceed to step 1:
407 can be fit into 5 0 times, resulting in a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Grab the next digit (2) from the dividend, add it to 5, then carry on: 52 / 407

Advancing to step 2:
If we divide 52 by 407, we get 0 and a remainder of 52.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 52 after subtracting 0 from 52.
Append the next digit (6) from the dividend to 52 and continue with: 526 / 407

Let's proceed to step 3:
407 goes into 526 1 times with a remainder of 119.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we subtract 407 from 526, we get 119.
Append the next digit (0) from the dividend to 119 and continue with: 1190 / 407

Let's proceed to step 4:
407 can be fit into 1190 2 times, resulting in a remainder of 376.
Put 2 as the next digit of the answer. 
Result so far: 12.0
If we take 814 away from 1190, we end up with 376.
Take the next digit (6) from the dividend and append it to 376, then repeat: 3766 / 407

Let's proceed to step 5:
3766 divided by 407 is 9 with a remainder of 103.
Record the quotient 9 as the next digit in the result. 
Result so far: 129.0
If we take 3663 away from 3766, we end up with 103.
Fetch the next digit (7) from the dividend, attach it to 103 and continue: 1037 / 407

Let's proceed to step 6:
407 can be fit into 1037 2 times, resulting in a remainder of 223.
Put 2 as the next digit of the answer. 
Result so far: 1292.0
The remainder is 223 after subtracting 814 from 1037.
Grab the next digit (9) from the dividend, add it to 223, then carry on: 2239 / 407

On to step 7:
When dividing 2239 by 407, we get 5 with a remainder of 204.
The number 5 becomes the next digit in our result. 
Result so far: 12925.0
If we subtract 2035 from 2239, we get 204.
Bring next digit (7) of the dividend behind the 204 and repeat the process: 2047 / 407

Step 8:
2047 divided by 407 is 5 with a remainder of 12.
Write down 5 as next digit of the result. 
Result so far: 129255.0
Subtracting 2035 from 2047 leaves us with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Step 9:
407 goes into 120 0 times with a remainder of 120.
Write down 0 as next digit of the result. 
Result so far: 129255.0
If we take 0 away from 120, we end up with 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Step 10:
407 goes into 1200 2 times with a remainder of 386.
Use 2 as the next digit of our solution. 
Result so far: 129255.02
If we subtract 814 from 1200, we get 386.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3860, and continue the process.

Moving on to step 11:
The number 407 fits into 3860 9 times, leaving a remainder of 197.
The number 9 becomes the next digit in our result. 
Result so far: 129255.029
Subtracting 3663 from 3860 leaves us with 197.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1970, and continue the process.

Step 12:
1970 divided by 407 is 4 with a remainder of 342.
Record the quotient 4 as the next digit in the result. 
Result so far: 129255.0294
Deduct 1628 from 1970 and we're left with 342.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3420, and continue the process.

Going ahead to step 13:
3420 divided by 407 is 8 with a remainder of 164.
Record the quotient 8 as the next digit in the result. 
Result so far: 129255.02948
Subtracting 3256 from 3420 leaves us with 164.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1640, and continue the process.

Going ahead to step 14:
407 can be fit into 1640 4 times, resulting in a remainder of 12.
The next digit of our result is 4. 
Result so far: 129255.029484
If we subtract 1628 from 1640, we get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Advancing to step 15:
If we divide 120 by 407, we get 0 and a remainder of 120.
The next digit of our result is 0. 
Result so far: 129255.029484
Subtract 0 from 120 to get 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Step 16:
If we divide 1200 by 407, we get 2 and a remainder of 386.
Write down 2 as next digit of the result. 
Result so far: 129255.02948402
Subtracting 814 from 1200 leaves us with 386.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3860, and continue the process.

Our division results in 129255.02948402 with a remaining 3.86e-07.
