Let's divide 77850435 by 537
The aim is to understand the frequency of 537 in 77850435.

Moving on to step 1:
The number 537 fits into 7 0 times, leaving a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Take the next digit (7) from the dividend and append it to 7, then repeat: 77 / 537

Let's proceed to step 2:
537 can be fit into 77 0 times, resulting in a remainder of 77.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 77, we get 77.
Grab the next digit (8) from the dividend, add it to 77, then carry on: 778 / 537

Step 3:
The number 537 fits into 778 1 times, leaving a remainder of 241.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we subtract 537 from 778, we get 241.
Include the next digit (5) from the dividend after 241, then repeat: 2415 / 537

On to step 4:
537 can be fit into 2415 4 times, resulting in a remainder of 267.
Use 4 as the next digit of our solution. 
Result so far: 14.0
If we take 2148 away from 2415, we end up with 267.
Append the next digit (0) from the dividend to 267 and continue with: 2670 / 537

Going ahead to step 5:
537 can be fit into 2670 4 times, resulting in a remainder of 522.
Record the quotient 4 as the next digit in the result. 
Result so far: 144.0
Deduct 2148 from 2670 and we're left with 522.
Append the next digit (4) from the dividend to 522 and continue with: 5224 / 537

Moving on to step 6:
The number 537 fits into 5224 9 times, leaving a remainder of 391.
The next digit of our result is 9. 
Result so far: 1449.0
The remainder is 391 after subtracting 4833 from 5224.
Take the next digit (3) from the dividend and append it to 391, then repeat: 3913 / 537

Moving on to step 7:
The number 537 fits into 3913 7 times, leaving a remainder of 154.
Use 7 as the next digit of our solution. 
Result so far: 14497.0
If we take 3759 away from 3913, we end up with 154.
Take the next digit (5) from the dividend and append it to 154, then repeat: 1545 / 537

Advancing to step 8:
The number 537 fits into 1545 2 times, leaving a remainder of 471.
The next digit of our result is 2. 
Result so far: 144972.0
If we subtract 1074 from 1545, 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.

On to step 9:
4710 divided by 537 is 8 with a remainder of 414.
Write down 8 as next digit of the result. 
Result so far: 144972.8
If we take 4296 away from 4710, we end up with 414.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4140, and continue the process.

Step 10:
When dividing 4140 by 537, we get 7 with a remainder of 381.
Use 7 as the next digit of our solution. 
Result so far: 144972.87
If we subtract 3759 from 4140, we get 381.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3810, and continue the process.

On to step 11:
When dividing 3810 by 537, we get 7 with a remainder of 51.
Record the quotient 7 as the next digit in the result. 
Result so far: 144972.877
If we subtract 3759 from 3810, we get 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

The quotient of the division is 144972.877, and the remainder is 0.0051.
