98802041 ÷ 421 
The aim is to understand the frequency of 421 in 98802041.

Going ahead to step 1:
9 divided by 421 is 0 with a remainder of 9.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 9 to get 9.
Bring next digit (8) of the dividend behind the 9 and repeat the process: 98 / 421

Advancing to step 2:
421 goes into 98 0 times with a remainder of 98.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 98, we get 98.
Include the next digit (8) from the dividend after 98, then repeat: 988 / 421

Step 3:
421 can be fit into 988 2 times, resulting in a remainder of 146.
Use 2 as the next digit of our solution. 
Result so far: 2.0
The remainder is 146 after subtracting 842 from 988.
Fetch the next digit (0) from the dividend, attach it to 146 and continue: 1460 / 421

Step 4:
If we divide 1460 by 421, we get 3 and a remainder of 197.
Record the quotient 3 as the next digit in the result. 
Result so far: 23.0
Subtracting 1263 from 1460 leaves us with 197.
Bring next digit (2) of the dividend behind the 197 and repeat the process: 1972 / 421

On to step 5:
The number 421 fits into 1972 4 times, leaving a remainder of 288.
The number 4 becomes the next digit in our result. 
Result so far: 234.0
Deduct 1684 from 1972 and we're left with 288.
Fetch the next digit (0) from the dividend, attach it to 288 and continue: 2880 / 421

Let's proceed to step 6:
421 goes into 2880 6 times with a remainder of 354.
Use 6 as the next digit of our solution. 
Result so far: 2346.0
If we subtract 2526 from 2880, we get 354.
Fetch the next digit (4) from the dividend, attach it to 354 and continue: 3544 / 421

Moving on to step 7:
When dividing 3544 by 421, we get 8 with a remainder of 176.
The number 8 becomes the next digit in our result. 
Result so far: 23468.0
Deduct 3368 from 3544 and we're left with 176.
Fetch the next digit (1) from the dividend, attach it to 176 and continue: 1761 / 421

Moving on to step 8:
When dividing 1761 by 421, we get 4 with a remainder of 77.
Write down 4 as next digit of the result. 
Result so far: 234684.0
Subtract 1684 from 1761 to get 77.
Since there are no more digits in the dividend, we add a zero to the remainder making it 770, and continue the process.

Step 9:
If we divide 770 by 421, we get 1 and a remainder of 349.
Put 1 as the next digit of the answer. 
Result so far: 234684.1
The remainder is 349 after subtracting 421 from 770.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3490, and continue the process.

Going ahead to step 10:
The number 421 fits into 3490 8 times, leaving a remainder of 122.
Use 8 as the next digit of our solution. 
Result so far: 234684.18
The remainder is 122 after subtracting 3368 from 3490.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1220, and continue the process.

Moving on to step 11:
When dividing 1220 by 421, we get 2 with a remainder of 378.
Write down 2 as next digit of the result. 
Result so far: 234684.182
The remainder is 378 after subtracting 842 from 1220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3780, and continue the process.

Let's proceed to step 12:
If we divide 3780 by 421, we get 8 and a remainder of 412.
Record the quotient 8 as the next digit in the result. 
Result so far: 234684.1828
Subtract 3368 from 3780 to get 412.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4120, and continue the process.

Step 13:
421 goes into 4120 9 times with a remainder of 331.
Use 9 as the next digit of our solution. 
Result so far: 234684.18289
Subtracting 3789 from 4120 leaves us with 331.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3310, and continue the process.

Moving on to step 14:
The number 421 fits into 3310 7 times, leaving a remainder of 363.
Use 7 as the next digit of our solution. 
Result so far: 234684.182897
Deduct 2947 from 3310 and we're left with 363.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3630, and continue the process.

Let's proceed to step 15:
421 can be fit into 3630 8 times, resulting in a remainder of 262.
Use 8 as the next digit of our solution. 
Result so far: 234684.1828978
Subtracting 3368 from 3630 leaves us with 262.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2620, and continue the process.

Going ahead to step 16:
When dividing 2620 by 421, we get 6 with a remainder of 94.
Put 6 as the next digit of the answer. 
Result so far: 234684.18289786
If we subtract 2526 from 2620, we get 94.
Since there are no more digits in the dividend, we add a zero to the remainder making it 940, and continue the process.

Our division results in 234684.18289786 with a remaining 9.4e-08.
