50045801 ÷ 653 
The aim is to understand the frequency of 653 in 50045801.

Advancing to step 1:
653 goes into 5 0 times with a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Fetch the next digit (0) from the dividend, attach it to 5 and continue: 50 / 653

On to step 2:
50 divided by 653 is 0 with a remainder of 50.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 50 and we're left with 50.
Include the next digit (0) from the dividend after 50, then repeat: 500 / 653

On to step 3:
653 goes into 500 0 times with a remainder of 500.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 500 after subtracting 0 from 500.
Take the next digit (4) from the dividend and append it to 500, then repeat: 5004 / 653

Advancing to step 4:
653 can be fit into 5004 7 times, resulting in a remainder of 433.
Put 7 as the next digit of the answer. 
Result so far: 7.0
If we subtract 4571 from 5004, we get 433.
Append the next digit (5) from the dividend to 433 and continue with: 4335 / 653

Step 5:
653 goes into 4335 6 times with a remainder of 417.
Record the quotient 6 as the next digit in the result. 
Result so far: 76.0
If we subtract 3918 from 4335, we get 417.
Grab the next digit (8) from the dividend, add it to 417, then carry on: 4178 / 653

Let's proceed to step 6:
653 can be fit into 4178 6 times, resulting in a remainder of 260.
Record the quotient 6 as the next digit in the result. 
Result so far: 766.0
If we take 3918 away from 4178, we end up with 260.
Grab the next digit (0) from the dividend, add it to 260, then carry on: 2600 / 653

On to step 7:
When dividing 2600 by 653, we get 3 with a remainder of 641.
The number 3 becomes the next digit in our result. 
Result so far: 7663.0
Subtracting 1959 from 2600 leaves us with 641.
Append the next digit (1) from the dividend to 641 and continue with: 6411 / 653

On to step 8:
6411 divided by 653 is 9 with a remainder of 534.
Write down 9 as next digit of the result. 
Result so far: 76639.0
If we take 5877 away from 6411, we end up with 534.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5340, and continue the process.

Going ahead to step 9:
The number 653 fits into 5340 8 times, leaving a remainder of 116.
Put 8 as the next digit of the answer. 
Result so far: 76639.8
Subtracting 5224 from 5340 leaves us with 116.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1160, and continue the process.

Step 10:
When dividing 1160 by 653, we get 1 with a remainder of 507.
Record the quotient 1 as the next digit in the result. 
Result so far: 76639.81
Deduct 653 from 1160 and we're left with 507.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5070, and continue the process.

Step 11:
653 goes into 5070 7 times with a remainder of 499.
The number 7 becomes the next digit in our result. 
Result so far: 76639.817
The remainder is 499 after subtracting 4571 from 5070.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4990, and continue the process.

Advancing to step 12:
The number 653 fits into 4990 7 times, leaving a remainder of 419.
Put 7 as the next digit of the answer. 
Result so far: 76639.8177
Subtracting 4571 from 4990 leaves us with 419.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4190, and continue the process.

The quotient of the division is 76639.8177, and the remainder is 0.00419.
