Let's divide 73107861 by 507
The aim is to understand the frequency of 507 in 73107861.

Step 1:
507 goes into 7 0 times with a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Fetch the next digit (3) from the dividend, attach it to 7 and continue: 73 / 507

Let's proceed to step 2:
If we divide 73 by 507, we get 0 and a remainder of 73.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 73 and we're left with 73.
Include the next digit (1) from the dividend after 73, then repeat: 731 / 507

Going ahead to step 3:
507 can be fit into 731 1 times, resulting in a remainder of 224.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we subtract 507 from 731, we get 224.
Include the next digit (0) from the dividend after 224, then repeat: 2240 / 507

On to step 4:
507 can be fit into 2240 4 times, resulting in a remainder of 212.
The number 4 becomes the next digit in our result. 
Result so far: 14.0
Subtract 2028 from 2240 to get 212.
Include the next digit (7) from the dividend after 212, then repeat: 2127 / 507

Moving on to step 5:
507 can be fit into 2127 4 times, resulting in a remainder of 99.
Record the quotient 4 as the next digit in the result. 
Result so far: 144.0
Subtracting 2028 from 2127 leaves us with 99.
Append the next digit (8) from the dividend to 99 and continue with: 998 / 507

Advancing to step 6:
The number 507 fits into 998 1 times, leaving a remainder of 491.
Write down 1 as next digit of the result. 
Result so far: 1441.0
The remainder is 491 after subtracting 507 from 998.
Fetch the next digit (6) from the dividend, attach it to 491 and continue: 4916 / 507

Moving on to step 7:
When dividing 4916 by 507, we get 9 with a remainder of 353.
The next digit of our result is 9. 
Result so far: 14419.0
If we subtract 4563 from 4916, we get 353.
Bring next digit (1) of the dividend behind the 353 and repeat the process: 3531 / 507

On to step 8:
507 can be fit into 3531 6 times, resulting in a remainder of 489.
Write down 6 as next digit of the result. 
Result so far: 144196.0
If we subtract 3042 from 3531, we get 489.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4890, and continue the process.

Step 9:
If we divide 4890 by 507, we get 9 and a remainder of 327.
Write down 9 as next digit of the result. 
Result so far: 144196.9
If we take 4563 away from 4890, we end up with 327.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3270, and continue the process.

On to step 10:
507 can be fit into 3270 6 times, resulting in a remainder of 228.
The next digit of our result is 6. 
Result so far: 144196.96
Subtract 3042 from 3270 to get 228.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2280, and continue the process.

Let's proceed to step 11:
When dividing 2280 by 507, we get 4 with a remainder of 252.
The number 4 becomes the next digit in our result. 
Result so far: 144196.964
If we take 2028 away from 2280, we end up with 252.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2520, and continue the process.

Going ahead to step 12:
507 goes into 2520 4 times with a remainder of 492.
Use 4 as the next digit of our solution. 
Result so far: 144196.9644
If we subtract 2028 from 2520, we get 492.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4920, and continue the process.

In conclusion, the division gives 144196.9644 with a balance of 0.00492.
