We're dividing 47723114 by 421 
The aim is to understand the frequency of 421 in 47723114.

Step 1:
If we divide 4 by 421, we get 0 and a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Bring next digit (7) of the dividend behind the 4 and repeat the process: 47 / 421

On to step 2:
421 can be fit into 47 0 times, resulting in a remainder of 47.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 47, we get 47.
Append the next digit (7) from the dividend to 47 and continue with: 477 / 421

Step 3:
421 goes into 477 1 times with a remainder of 56.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Deduct 421 from 477 and we're left with 56.
Append the next digit (2) from the dividend to 56 and continue with: 562 / 421

On to step 4:
When dividing 562 by 421, we get 1 with a remainder of 141.
Write down 1 as next digit of the result. 
Result so far: 11.0
Subtract 421 from 562 to get 141.
Include the next digit (3) from the dividend after 141, then repeat: 1413 / 421

Moving on to step 5:
The number 421 fits into 1413 3 times, leaving a remainder of 150.
Write down 3 as next digit of the result. 
Result so far: 113.0
If we subtract 1263 from 1413, we get 150.
Bring next digit (1) of the dividend behind the 150 and repeat the process: 1501 / 421

Step 6:
1501 divided by 421 is 3 with a remainder of 238.
The number 3 becomes the next digit in our result. 
Result so far: 1133.0
Subtracting 1263 from 1501 leaves us with 238.
Fetch the next digit (1) from the dividend, attach it to 238 and continue: 2381 / 421

On to step 7:
If we divide 2381 by 421, we get 5 and a remainder of 276.
The next digit of our result is 5. 
Result so far: 11335.0
Subtracting 2105 from 2381 leaves us with 276.
Append the next digit (4) from the dividend to 276 and continue with: 2764 / 421

On to step 8:
2764 divided by 421 is 6 with a remainder of 238.
The number 6 becomes the next digit in our result. 
Result so far: 113356.0
The remainder is 238 after subtracting 2526 from 2764.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2380, and continue the process.

Let's proceed to step 9:
When dividing 2380 by 421, we get 5 with a remainder of 275.
Use 5 as the next digit of our solution. 
Result so far: 113356.5
Deduct 2105 from 2380 and we're left with 275.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2750, and continue the process.

On to step 10:
421 goes into 2750 6 times with a remainder of 224.
Put 6 as the next digit of the answer. 
Result so far: 113356.56
Subtract 2526 from 2750 to get 224.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2240, and continue the process.

Step 11:
If we divide 2240 by 421, we get 5 and a remainder of 135.
The number 5 becomes the next digit in our result. 
Result so far: 113356.565
If we take 2105 away from 2240, we end up with 135.
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 12:
If we divide 1350 by 421, we get 3 and a remainder of 87.
Record the quotient 3 as the next digit in the result. 
Result so far: 113356.5653
Deduct 1263 from 1350 and we're left with 87.
Since there are no more digits in the dividend, we add a zero to the remainder making it 870, and continue the process.

Moving on to step 13:
421 goes into 870 2 times with a remainder of 28.
Record the quotient 2 as the next digit in the result. 
Result so far: 113356.56532
Deduct 842 from 870 and we're left with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Step 14:
421 goes into 280 0 times with a remainder of 280.
Record the quotient 0 as the next digit in the result. 
Result so far: 113356.56532
Subtract 0 from 280 to get 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 15:
When dividing 2800 by 421, we get 6 with a remainder of 274.
Use 6 as the next digit of our solution. 
Result so far: 113356.5653206
If we subtract 2526 from 2800, we 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 16:
The number 421 fits into 2740 6 times, leaving a remainder of 214.
Use 6 as the next digit of our solution. 
Result so far: 113356.56532066
The remainder is 214 after subtracting 2526 from 2740.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2140, and continue the process.

The final outcome is 113356.56532066, with a leftover of 2.14e-07.
