54315866 divided by 537 
The aim is to understand the frequency of 537 in 54315866.

Step 1:
537 can be fit into 5 0 times, resulting in a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Include the next digit (4) from the dividend after 5, then repeat: 54 / 537

Step 2:
The number 537 fits into 54 0 times, leaving a remainder of 54.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 54, we end up with 54.
Include the next digit (3) from the dividend after 54, then repeat: 543 / 537

Advancing to step 3:
The number 537 fits into 543 1 times, leaving a remainder of 6.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we take 537 away from 543, we end up with 6.
Grab the next digit (1) from the dividend, add it to 6, then carry on: 61 / 537

Going ahead to step 4:
If we divide 61 by 537, we get 0 and a remainder of 61.
Write down 0 as next digit of the result. 
Result so far: 10.0
Subtract 0 from 61 to get 61.
Grab the next digit (5) from the dividend, add it to 61, then carry on: 615 / 537

Let's proceed to step 5:
615 divided by 537 is 1 with a remainder of 78.
The next digit of our result is 1. 
Result so far: 101.0
Subtract 537 from 615 to get 78.
Take the next digit (8) from the dividend and append it to 78, then repeat: 788 / 537

Going ahead to step 6:
788 divided by 537 is 1 with a remainder of 251.
Put 1 as the next digit of the answer. 
Result so far: 1011.0
The remainder is 251 after subtracting 537 from 788.
Bring next digit (6) of the dividend behind the 251 and repeat the process: 2516 / 537

Step 7:
537 goes into 2516 4 times with a remainder of 368.
Write down 4 as next digit of the result. 
Result so far: 10114.0
The remainder is 368 after subtracting 2148 from 2516.
Take the next digit (6) from the dividend and append it to 368, then repeat: 3686 / 537

On to step 8:
537 can be fit into 3686 6 times, resulting in a remainder of 464.
The next digit of our result is 6. 
Result so far: 101146.0
Subtracting 3222 from 3686 leaves us with 464.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4640, and continue the process.

Let's proceed to step 9:
If we divide 4640 by 537, we get 8 and a remainder of 344.
The next digit of our result is 8. 
Result so far: 101146.8
Subtracting 4296 from 4640 leaves us with 344.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3440, and continue the process.

On to step 10:
If we divide 3440 by 537, we get 6 and a remainder of 218.
Put 6 as the next digit of the answer. 
Result so far: 101146.86
Subtracting 3222 from 3440 leaves us with 218.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2180, and continue the process.

Moving on to step 11:
537 goes into 2180 4 times with a remainder of 32.
Put 4 as the next digit of the answer. 
Result so far: 101146.864
Deduct 2148 from 2180 and we're left with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Going ahead to step 12:
320 divided by 537 is 0 with a remainder of 320.
The next digit of our result is 0. 
Result so far: 101146.864
If we subtract 0 from 320, we get 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

Let's proceed to step 13:
537 can be fit into 3200 5 times, resulting in a remainder of 515.
The number 5 becomes the next digit in our result. 
Result so far: 101146.86405
The remainder is 515 after subtracting 2685 from 3200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5150, and continue the process.

Moving on to step 14:
537 can be fit into 5150 9 times, resulting in a remainder of 317.
Put 9 as the next digit of the answer. 
Result so far: 101146.864059
If we take 4833 away from 5150, we end up with 317.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3170, and continue the process.

Going ahead to step 15:
537 can be fit into 3170 5 times, resulting in a remainder of 485.
Use 5 as the next digit of our solution. 
Result so far: 101146.8640595
If we take 2685 away from 3170, we end up with 485.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4850, and continue the process.

Going ahead to step 16:
The number 537 fits into 4850 9 times, leaving a remainder of 17.
The number 9 becomes the next digit in our result. 
Result so far: 101146.86405959
If we subtract 4833 from 4850, we get 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

After the division, we end up with 101146.86405959 and a remainder of 1.7e-08.
