We're dividing 55905612 by 507 
The aim is to understand the frequency of 507 in 55905612.

Step 1:
The number 507 fits into 5 0 times, leaving a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Append the next digit (5) from the dividend to 5 and continue with: 55 / 507

Step 2:
55 divided by 507 is 0 with a remainder of 55.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 55, we get 55.
Bring next digit (9) of the dividend behind the 55 and repeat the process: 559 / 507

Step 3:
When dividing 559 by 507, we get 1 with a remainder of 52.
The next digit of our result is 1. 
Result so far: 1.0
If we take 507 away from 559, we end up with 52.
Bring next digit (0) of the dividend behind the 52 and repeat the process: 520 / 507

Advancing to step 4:
When dividing 520 by 507, we get 1 with a remainder of 13.
Use 1 as the next digit of our solution. 
Result so far: 11.0
Subtract 507 from 520 to get 13.
Grab the next digit (5) from the dividend, add it to 13, then carry on: 135 / 507

Advancing to step 5:
If we divide 135 by 507, we get 0 and a remainder of 135.
Use 0 as the next digit of our solution. 
Result so far: 110.0
If we subtract 0 from 135, we get 135.
Fetch the next digit (6) from the dividend, attach it to 135 and continue: 1356 / 507

Going ahead to step 6:
The number 507 fits into 1356 2 times, leaving a remainder of 342.
The number 2 becomes the next digit in our result. 
Result so far: 1102.0
The remainder is 342 after subtracting 1014 from 1356.
Fetch the next digit (1) from the dividend, attach it to 342 and continue: 3421 / 507

Going ahead to step 7:
If we divide 3421 by 507, we get 6 and a remainder of 379.
The number 6 becomes the next digit in our result. 
Result so far: 11026.0
Subtract 3042 from 3421 to get 379.
Take the next digit (2) from the dividend and append it to 379, then repeat: 3792 / 507

Step 8:
If we divide 3792 by 507, we get 7 and a remainder of 243.
Record the quotient 7 as the next digit in the result. 
Result so far: 110267.0
The remainder is 243 after subtracting 3549 from 3792.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2430, and continue the process.

Advancing to step 9:
If we divide 2430 by 507, we get 4 and a remainder of 402.
Record the quotient 4 as the next digit in the result. 
Result so far: 110267.4
Deduct 2028 from 2430 and we're left with 402.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4020, and continue the process.

Let's proceed to step 10:
If we divide 4020 by 507, we get 7 and a remainder of 471.
Put 7 as the next digit of the answer. 
Result so far: 110267.47
If we subtract 3549 from 4020, we get 471.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4710, and continue the process.

Step 11:
When dividing 4710 by 507, we get 9 with a remainder of 147.
Put 9 as the next digit of the answer. 
Result so far: 110267.479
Subtract 4563 from 4710 to get 147.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1470, and continue the process.

Let's proceed to step 12:
507 can be fit into 1470 2 times, resulting in a remainder of 456.
The next digit of our result is 2. 
Result so far: 110267.4792
If we take 1014 away from 1470, we end up with 456.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4560, and continue the process.

On to step 13:
507 can be fit into 4560 8 times, resulting in a remainder of 504.
The next digit of our result is 8. 
Result so far: 110267.47928
Deduct 4056 from 4560 and we're left with 504.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5040, and continue the process.

On to step 14:
5040 divided by 507 is 9 with a remainder of 477.
Record the quotient 9 as the next digit in the result. 
Result so far: 110267.479289
Deduct 4563 from 5040 and we're left with 477.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4770, and continue the process.

On to step 15:
507 can be fit into 4770 9 times, resulting in a remainder of 207.
The next digit of our result is 9. 
Result so far: 110267.4792899
Subtracting 4563 from 4770 leaves us with 207.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2070, and continue the process.

After the division, we end up with 110267.4792899 and a remainder of 2.07e-06.
