51845069 ÷ 507 
The aim is to understand the frequency of 507 in 51845069.

Moving on to step 1:
5 divided by 507 is 0 with a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Bring next digit (1) of the dividend behind the 5 and repeat the process: 51 / 507

Advancing to step 2:
507 can be fit into 51 0 times, resulting in a remainder of 51.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 51 leaves us with 51.
Append the next digit (8) from the dividend to 51 and continue with: 518 / 507

Step 3:
When dividing 518 by 507, we get 1 with a remainder of 11.
The next digit of our result is 1. 
Result so far: 1.0
If we take 507 away from 518, we end up with 11.
Include the next digit (4) from the dividend after 11, then repeat: 114 / 507

Let's proceed to step 4:
The number 507 fits into 114 0 times, leaving a remainder of 114.
Write down 0 as next digit of the result. 
Result so far: 10.0
If we subtract 0 from 114, we get 114.
Fetch the next digit (5) from the dividend, attach it to 114 and continue: 1145 / 507

Let's proceed to step 5:
If we divide 1145 by 507, we get 2 and a remainder of 131.
The number 2 becomes the next digit in our result. 
Result so far: 102.0
If we subtract 1014 from 1145, we get 131.
Grab the next digit (0) from the dividend, add it to 131, then carry on: 1310 / 507

Moving on to step 6:
If we divide 1310 by 507, we get 2 and a remainder of 296.
The next digit of our result is 2. 
Result so far: 1022.0
If we subtract 1014 from 1310, we get 296.
Append the next digit (6) from the dividend to 296 and continue with: 2966 / 507

Going ahead to step 7:
When dividing 2966 by 507, we get 5 with a remainder of 431.
The next digit of our result is 5. 
Result so far: 10225.0
Subtracting 2535 from 2966 leaves us with 431.
Bring next digit (9) of the dividend behind the 431 and repeat the process: 4319 / 507

Let's proceed to step 8:
4319 divided by 507 is 8 with a remainder of 263.
The next digit of our result is 8. 
Result so far: 102258.0
Subtract 4056 from 4319 to get 263.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2630, and continue the process.

Moving on to step 9:
507 goes into 2630 5 times with a remainder of 95.
The number 5 becomes the next digit in our result. 
Result so far: 102258.5
The remainder is 95 after subtracting 2535 from 2630.
Since there are no more digits in the dividend, we add a zero to the remainder making it 950, and continue the process.

Moving on to step 10:
950 divided by 507 is 1 with a remainder of 443.
Use 1 as the next digit of our solution. 
Result so far: 102258.51
Deduct 507 from 950 and we're left with 443.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4430, and continue the process.

Moving on to step 11:
If we divide 4430 by 507, we get 8 and a remainder of 374.
Record the quotient 8 as the next digit in the result. 
Result so far: 102258.518
Deduct 4056 from 4430 and we're left with 374.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3740, and continue the process.

Moving on to step 12:
507 goes into 3740 7 times with a remainder of 191.
The number 7 becomes the next digit in our result. 
Result so far: 102258.5187
Subtracting 3549 from 3740 leaves us with 191.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1910, and continue the process.

Step 13:
When dividing 1910 by 507, we get 3 with a remainder of 389.
Write down 3 as next digit of the result. 
Result so far: 102258.51873
The remainder is 389 after subtracting 1521 from 1910.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3890, and continue the process.

Step 14:
If we divide 3890 by 507, we get 7 and a remainder of 341.
Put 7 as the next digit of the answer. 
Result so far: 102258.518737
Subtract 3549 from 3890 to get 341.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3410, and continue the process.

Moving on to step 15:
If we divide 3410 by 507, we get 6 and a remainder of 368.
Put 6 as the next digit of the answer. 
Result so far: 102258.5187376
Subtracting 3042 from 3410 leaves us with 368.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3680, and continue the process.

Let's proceed to step 16:
When dividing 3680 by 507, we get 7 with a remainder of 131.
Use 7 as the next digit of our solution. 
Result so far: 102258.51873767
If we take 3549 away from 3680, we end up with 131.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1310, and continue the process.

The quotient of the division is 102258.51873767, and the remainder is 1.31e-07.
