We're dividing 51430118 by 633 
The aim is to understand the frequency of 633 in 51430118.

Step 1:
633 can be fit into 5 0 times, resulting in a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Append the next digit (1) from the dividend to 5 and continue with: 51 / 633

Moving on to step 2:
51 divided by 633 is 0 with a remainder of 51.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 51 leaves us with 51.
Grab the next digit (4) from the dividend, add it to 51, then carry on: 514 / 633

Step 3:
633 can be fit into 514 0 times, resulting in a remainder of 514.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 514 after subtracting 0 from 514.
Grab the next digit (3) from the dividend, add it to 514, then carry on: 5143 / 633

Moving on to step 4:
633 goes into 5143 8 times with a remainder of 79.
Use 8 as the next digit of our solution. 
Result so far: 8.0
The remainder is 79 after subtracting 5064 from 5143.
Include the next digit (0) from the dividend after 79, then repeat: 790 / 633

Moving on to step 5:
If we divide 790 by 633, we get 1 and a remainder of 157.
The next digit of our result is 1. 
Result so far: 81.0
The remainder is 157 after subtracting 633 from 790.
Append the next digit (1) from the dividend to 157 and continue with: 1571 / 633

Step 6:
When dividing 1571 by 633, we get 2 with a remainder of 305.
Use 2 as the next digit of our solution. 
Result so far: 812.0
Deduct 1266 from 1571 and we're left with 305.
Include the next digit (1) from the dividend after 305, then repeat: 3051 / 633

Step 7:
When dividing 3051 by 633, we get 4 with a remainder of 519.
The next digit of our result is 4. 
Result so far: 8124.0
If we take 2532 away from 3051, we end up with 519.
Grab the next digit (8) from the dividend, add it to 519, then carry on: 5198 / 633

Step 8:
The number 633 fits into 5198 8 times, leaving a remainder of 134.
Record the quotient 8 as the next digit in the result. 
Result so far: 81248.0
Subtract 5064 from 5198 to get 134.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1340, and continue the process.

Advancing to step 9:
1340 divided by 633 is 2 with a remainder of 74.
The number 2 becomes the next digit in our result. 
Result so far: 81248.2
Deduct 1266 from 1340 and we're left with 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

Advancing to step 10:
When dividing 740 by 633, we get 1 with a remainder of 107.
Write down 1 as next digit of the result. 
Result so far: 81248.21
Subtracting 633 from 740 leaves us with 107.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1070, and continue the process.

Step 11:
1070 divided by 633 is 1 with a remainder of 437.
The next digit of our result is 1. 
Result so far: 81248.211
The remainder is 437 after subtracting 633 from 1070.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4370, and continue the process.

After the division, we end up with 81248.211 and a remainder of 0.0437.
