We're dividing 29786376 by 401 
The aim is to understand the frequency of 401 in 29786376.

Let's proceed to step 1:
The number 401 fits into 2 0 times, leaving a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Fetch the next digit (9) from the dividend, attach it to 2 and continue: 29 / 401

Step 2:
401 can be fit into 29 0 times, resulting in a remainder of 29.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 29 and we're left with 29.
Include the next digit (7) from the dividend after 29, then repeat: 297 / 401

Moving on to step 3:
401 can be fit into 297 0 times, resulting in a remainder of 297.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 297 to get 297.
Fetch the next digit (8) from the dividend, attach it to 297 and continue: 2978 / 401

Step 4:
If we divide 2978 by 401, we get 7 and a remainder of 171.
The number 7 becomes the next digit in our result. 
Result so far: 7.0
If we subtract 2807 from 2978, we get 171.
Grab the next digit (6) from the dividend, add it to 171, then carry on: 1716 / 401

Step 5:
401 goes into 1716 4 times with a remainder of 112.
The next digit of our result is 4. 
Result so far: 74.0
Subtract 1604 from 1716 to get 112.
Grab the next digit (3) from the dividend, add it to 112, then carry on: 1123 / 401

Going ahead to step 6:
When dividing 1123 by 401, we get 2 with a remainder of 321.
Record the quotient 2 as the next digit in the result. 
Result so far: 742.0
Subtracting 802 from 1123 leaves us with 321.
Bring next digit (7) of the dividend behind the 321 and repeat the process: 3217 / 401

Moving on to step 7:
401 goes into 3217 8 times with a remainder of 9.
Write down 8 as next digit of the result. 
Result so far: 7428.0
Subtract 3208 from 3217 to get 9.
Append the next digit (6) from the dividend to 9 and continue with: 96 / 401

On to step 8:
The number 401 fits into 96 0 times, leaving a remainder of 96.
The next digit of our result is 0. 
Result so far: 74280.0
The remainder is 96 after subtracting 0 from 96.
Since there are no more digits in the dividend, we add a zero to the remainder making it 960, and continue the process.

On to step 9:
960 divided by 401 is 2 with a remainder of 158.
The next digit of our result is 2. 
Result so far: 74280.2
Subtracting 802 from 960 leaves us with 158.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1580, and continue the process.

Moving on to step 10:
The number 401 fits into 1580 3 times, leaving a remainder of 377.
Write down 3 as next digit of the result. 
Result so far: 74280.23
The remainder is 377 after subtracting 1203 from 1580.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3770, and continue the process.

On to step 11:
401 can be fit into 3770 9 times, resulting in a remainder of 161.
Put 9 as the next digit of the answer. 
Result so far: 74280.239
If we take 3609 away from 3770, we end up with 161.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1610, and continue the process.

On to step 12:
1610 divided by 401 is 4 with a remainder of 6.
The next digit of our result is 4. 
Result so far: 74280.2394
Deduct 1604 from 1610 and we're left with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Step 13:
When dividing 60 by 401, we get 0 with a remainder of 60.
Write down 0 as next digit of the result. 
Result so far: 74280.2394
Deduct 0 from 60 and we're left with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Step 14:
If we divide 600 by 401, we get 1 and a remainder of 199.
Use 1 as the next digit of our solution. 
Result so far: 74280.239401
Deduct 401 from 600 and we're left with 199.
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 15:
When dividing 1990 by 401, we get 4 with a remainder of 386.
The number 4 becomes the next digit in our result. 
Result so far: 74280.2394014
Deduct 1604 from 1990 and we're left with 386.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3860, and continue the process.

Step 16:
3860 divided by 401 is 9 with a remainder of 251.
The number 9 becomes the next digit in our result. 
Result so far: 74280.23940149
If we take 3609 away from 3860, we end up with 251.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2510, and continue the process.

The quotient of the division is 74280.23940149, and the remainder is 2.51e-07.
