We divide 68043462 by 421
The aim is to understand the frequency of 421 in 68043462.

Advancing to step 1:
421 goes into 6 0 times with a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Take the next digit (8) from the dividend and append it to 6, then repeat: 68 / 421

Advancing to step 2:
68 divided by 421 is 0 with a remainder of 68.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 68 leaves us with 68.
Fetch the next digit (0) from the dividend, attach it to 68 and continue: 680 / 421

Advancing to step 3:
421 can be fit into 680 1 times, resulting in a remainder of 259.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtracting 421 from 680 leaves us with 259.
Include the next digit (4) from the dividend after 259, then repeat: 2594 / 421

Step 4:
421 can be fit into 2594 6 times, resulting in a remainder of 68.
Record the quotient 6 as the next digit in the result. 
Result so far: 16.0
If we take 2526 away from 2594, we end up with 68.
Grab the next digit (3) from the dividend, add it to 68, then carry on: 683 / 421

Step 5:
When dividing 683 by 421, we get 1 with a remainder of 262.
Record the quotient 1 as the next digit in the result. 
Result so far: 161.0
If we subtract 421 from 683, we get 262.
Bring next digit (4) of the dividend behind the 262 and repeat the process: 2624 / 421

On to step 6:
When dividing 2624 by 421, we get 6 with a remainder of 98.
Put 6 as the next digit of the answer. 
Result so far: 1616.0
The remainder is 98 after subtracting 2526 from 2624.
Take the next digit (6) from the dividend and append it to 98, then repeat: 986 / 421

On to step 7:
421 can be fit into 986 2 times, resulting in a remainder of 144.
The next digit of our result is 2. 
Result so far: 16162.0
If we subtract 842 from 986, we get 144.
Fetch the next digit (2) from the dividend, attach it to 144 and continue: 1442 / 421

Moving on to step 8:
When dividing 1442 by 421, we get 3 with a remainder of 179.
Put 3 as the next digit of the answer. 
Result so far: 161623.0
If we take 1263 away from 1442, we end up with 179.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1790, and continue the process.

Let's proceed to step 9:
1790 divided by 421 is 4 with a remainder of 106.
Put 4 as the next digit of the answer. 
Result so far: 161623.4
Deduct 1684 from 1790 and we're left with 106.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1060, and continue the process.

Step 10:
The number 421 fits into 1060 2 times, leaving a remainder of 218.
Record the quotient 2 as the next digit in the result. 
Result so far: 161623.42
If we take 842 away from 1060, we end up with 218.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2180, and continue the process.

Going ahead to step 11:
When dividing 2180 by 421, we get 5 with a remainder of 75.
Record the quotient 5 as the next digit in the result. 
Result so far: 161623.425
Subtracting 2105 from 2180 leaves us with 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Advancing to step 12:
421 can be fit into 750 1 times, resulting in a remainder of 329.
The number 1 becomes the next digit in our result. 
Result so far: 161623.4251
The remainder is 329 after subtracting 421 from 750.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3290, and continue the process.

Moving on to step 13:
3290 divided by 421 is 7 with a remainder of 343.
Record the quotient 7 as the next digit in the result. 
Result so far: 161623.42517
If we take 2947 away from 3290, we end up with 343.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3430, and continue the process.

Let's proceed to step 14:
When dividing 3430 by 421, we get 8 with a remainder of 62.
Record the quotient 8 as the next digit in the result. 
Result so far: 161623.425178
If we subtract 3368 from 3430, we get 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Going ahead to step 15:
The number 421 fits into 620 1 times, leaving a remainder of 199.
Use 1 as the next digit of our solution. 
Result so far: 161623.4251781
The remainder is 199 after subtracting 421 from 620.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1990, and continue the process.

Let's proceed to step 16:
If we divide 1990 by 421, we get 4 and a remainder of 306.
The next digit of our result is 4. 
Result so far: 161623.42517814
Subtract 1684 from 1990 to get 306.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3060, and continue the process.

Our division results in 161623.42517814 with a remaining 3.06e-07.
