29477122 divided by 401 
The aim is to understand the frequency of 401 in 29477122.

On to step 1:
401 goes into 2 0 times with a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Bring next digit (9) of the dividend behind the 2 and repeat the process: 29 / 401

Let's proceed to step 2:
29 divided by 401 is 0 with a remainder of 29.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 29, we get 29.
Fetch the next digit (4) from the dividend, attach it to 29 and continue: 294 / 401

Moving on to step 3:
401 can be fit into 294 0 times, resulting in a remainder of 294.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 294 and we're left with 294.
Append the next digit (7) from the dividend to 294 and continue with: 2947 / 401

On to step 4:
401 can be fit into 2947 7 times, resulting in a remainder of 140.
Use 7 as the next digit of our solution. 
Result so far: 7.0
If we subtract 2807 from 2947, we get 140.
Bring next digit (7) of the dividend behind the 140 and repeat the process: 1407 / 401

On to step 5:
401 goes into 1407 3 times with a remainder of 204.
Record the quotient 3 as the next digit in the result. 
Result so far: 73.0
Deduct 1203 from 1407 and we're left with 204.
Include the next digit (1) from the dividend after 204, then repeat: 2041 / 401

On to step 6:
401 goes into 2041 5 times with a remainder of 36.
Record the quotient 5 as the next digit in the result. 
Result so far: 735.0
If we take 2005 away from 2041, we end up with 36.
Take the next digit (2) from the dividend and append it to 36, then repeat: 362 / 401

On to step 7:
If we divide 362 by 401, we get 0 and a remainder of 362.
The next digit of our result is 0. 
Result so far: 7350.0
Subtract 0 from 362 to get 362.
Bring next digit (2) of the dividend behind the 362 and repeat the process: 3622 / 401

Moving on to step 8:
When dividing 3622 by 401, we get 9 with a remainder of 13.
The next digit of our result is 9. 
Result so far: 73509.0
If we subtract 3609 from 3622, we get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Moving on to step 9:
If we divide 130 by 401, we get 0 and a remainder of 130.
Record the quotient 0 as the next digit in the result. 
Result so far: 73509.0
The remainder is 130 after subtracting 0 from 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

Step 10:
401 can be fit into 1300 3 times, resulting in a remainder of 97.
Use 3 as the next digit of our solution. 
Result so far: 73509.03
If we take 1203 away from 1300, we end up with 97.
Since there are no more digits in the dividend, we add a zero to the remainder making it 970, and continue the process.

Advancing to step 11:
If we divide 970 by 401, we get 2 and a remainder of 168.
The number 2 becomes the next digit in our result. 
Result so far: 73509.032
Deduct 802 from 970 and we're left with 168.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1680, and continue the process.

Let's proceed to step 12:
If we divide 1680 by 401, we get 4 and a remainder of 76.
The next digit of our result is 4. 
Result so far: 73509.0324
Subtracting 1604 from 1680 leaves us with 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Advancing to step 13:
The number 401 fits into 760 1 times, leaving a remainder of 359.
Use 1 as the next digit of our solution. 
Result so far: 73509.03241
If we take 401 away from 760, we end up with 359.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3590, and continue the process.

Moving on to step 14:
The number 401 fits into 3590 8 times, leaving a remainder of 382.
Put 8 as the next digit of the answer. 
Result so far: 73509.032418
Subtracting 3208 from 3590 leaves us with 382.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3820, and continue the process.

Step 15:
If we divide 3820 by 401, we get 9 and a remainder of 211.
The number 9 becomes the next digit in our result. 
Result so far: 73509.0324189
Subtracting 3609 from 3820 leaves us with 211.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2110, and continue the process.

Going ahead to step 16:
The number 401 fits into 2110 5 times, leaving a remainder of 105.
Use 5 as the next digit of our solution. 
Result so far: 73509.03241895
The remainder is 105 after subtracting 2005 from 2110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1050, and continue the process.

The final outcome is 73509.03241895, with a leftover of 1.05e-07.
