41865306 divided by 421 
The aim is to understand the frequency of 421 in 41865306.

Advancing to step 1:
421 can be fit into 4 0 times, resulting in a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Grab the next digit (1) from the dividend, add it to 4, then carry on: 41 / 421

Moving on to step 2:
41 divided by 421 is 0 with a remainder of 41.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 41, we get 41.
Grab the next digit (8) from the dividend, add it to 41, then carry on: 418 / 421

On to step 3:
If we divide 418 by 421, we get 0 and a remainder of 418.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 418 leaves us with 418.
Take the next digit (6) from the dividend and append it to 418, then repeat: 4186 / 421

Moving on to step 4:
The number 421 fits into 4186 9 times, leaving a remainder of 397.
The next digit of our result is 9. 
Result so far: 9.0
Subtract 3789 from 4186 to get 397.
Grab the next digit (5) from the dividend, add it to 397, then carry on: 3975 / 421

Advancing to step 5:
When dividing 3975 by 421, we get 9 with a remainder of 186.
Record the quotient 9 as the next digit in the result. 
Result so far: 99.0
Subtract 3789 from 3975 to get 186.
Fetch the next digit (3) from the dividend, attach it to 186 and continue: 1863 / 421

Advancing to step 6:
1863 divided by 421 is 4 with a remainder of 179.
Record the quotient 4 as the next digit in the result. 
Result so far: 994.0
Subtract 1684 from 1863 to get 179.
Take the next digit (0) from the dividend and append it to 179, then repeat: 1790 / 421

Moving on to step 7:
If we divide 1790 by 421, we get 4 and a remainder of 106.
The next digit of our result is 4. 
Result so far: 9944.0
If we take 1684 away from 1790, we end up with 106.
Include the next digit (6) from the dividend after 106, then repeat: 1066 / 421

On to step 8:
When dividing 1066 by 421, we get 2 with a remainder of 224.
Use 2 as the next digit of our solution. 
Result so far: 99442.0
Subtracting 842 from 1066 leaves us with 224.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2240, and continue the process.

Going ahead to step 9:
The number 421 fits into 2240 5 times, leaving a remainder of 135.
Put 5 as the next digit of the answer. 
Result so far: 99442.5
The remainder is 135 after subtracting 2105 from 2240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1350, and continue the process.

Let's proceed to step 10:
The number 421 fits into 1350 3 times, leaving a remainder of 87.
The next digit of our result is 3. 
Result so far: 99442.53
If we subtract 1263 from 1350, we get 87.
Since there are no more digits in the dividend, we add a zero to the remainder making it 870, and continue the process.

On to step 11:
421 goes into 870 2 times with a remainder of 28.
Use 2 as the next digit of our solution. 
Result so far: 99442.532
The remainder is 28 after subtracting 842 from 870.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Step 12:
The number 421 fits into 280 0 times, leaving a remainder of 280.
Record the quotient 0 as the next digit in the result. 
Result so far: 99442.532
Deduct 0 from 280 and we're left with 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

On to step 13:
The number 421 fits into 2800 6 times, leaving a remainder of 274.
Write down 6 as next digit of the result. 
Result so far: 99442.53206
Subtract 2526 from 2800 to get 274.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2740, and continue the process.

Going ahead to step 14:
421 can be fit into 2740 6 times, resulting in a remainder of 214.
The next digit of our result is 6. 
Result so far: 99442.532066
Subtracting 2526 from 2740 leaves us with 214.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2140, and continue the process.

Our division results in 99442.532066 with a remaining 2.14e-05.
