We're dividing 50393244 by 658 
The aim is to understand the frequency of 658 in 50393244.

On to step 1:
658 goes into 5 0 times with a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Fetch the next digit (0) from the dividend, attach it to 5 and continue: 50 / 658

Step 2:
If we divide 50 by 658, we get 0 and a remainder of 50.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 50, we end up with 50.
Append the next digit (3) from the dividend to 50 and continue with: 503 / 658

Step 3:
658 goes into 503 0 times with a remainder of 503.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 503 and we're left with 503.
Take the next digit (9) from the dividend and append it to 503, then repeat: 5039 / 658

Going ahead to step 4:
If we divide 5039 by 658, we get 7 and a remainder of 433.
Use 7 as the next digit of our solution. 
Result so far: 7.0
If we take 4606 away from 5039, we end up with 433.
Grab the next digit (3) from the dividend, add it to 433, then carry on: 4333 / 658

Advancing to step 5:
When dividing 4333 by 658, we get 6 with a remainder of 385.
Put 6 as the next digit of the answer. 
Result so far: 76.0
Subtract 3948 from 4333 to get 385.
Fetch the next digit (2) from the dividend, attach it to 385 and continue: 3852 / 658

Step 6:
The number 658 fits into 3852 5 times, leaving a remainder of 562.
The next digit of our result is 5. 
Result so far: 765.0
If we take 3290 away from 3852, we end up with 562.
Fetch the next digit (4) from the dividend, attach it to 562 and continue: 5624 / 658

Moving on to step 7:
658 goes into 5624 8 times with a remainder of 360.
Write down 8 as next digit of the result. 
Result so far: 7658.0
The remainder is 360 after subtracting 5264 from 5624.
Include the next digit (4) from the dividend after 360, then repeat: 3604 / 658

Advancing to step 8:
When dividing 3604 by 658, we get 5 with a remainder of 314.
Record the quotient 5 as the next digit in the result. 
Result so far: 76585.0
If we take 3290 away from 3604, we end up with 314.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3140, and continue the process.

Going ahead to step 9:
When dividing 3140 by 658, we get 4 with a remainder of 508.
The number 4 becomes the next digit in our result. 
Result so far: 76585.4
If we take 2632 away from 3140, we end up with 508.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5080, and continue the process.

Moving on to step 10:
658 can be fit into 5080 7 times, resulting in a remainder of 474.
Record the quotient 7 as the next digit in the result. 
Result so far: 76585.47
If we take 4606 away from 5080, we end up with 474.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4740, and continue the process.

Going ahead to step 11:
658 can be fit into 4740 7 times, resulting in a remainder of 134.
Write down 7 as next digit of the result. 
Result so far: 76585.477
Subtract 4606 from 4740 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.

The final outcome is 76585.477, with a leftover of 0.0134.
