58709240 ÷ 401 
The aim is to understand the frequency of 401 in 58709240.

Let's proceed to step 1:
5 divided by 401 is 0 with a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Include the next digit (8) from the dividend after 5, then repeat: 58 / 401

Moving on to step 2:
58 divided by 401 is 0 with a remainder of 58.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 58, we get 58.
Append the next digit (7) from the dividend to 58 and continue with: 587 / 401

Let's proceed to step 3:
401 goes into 587 1 times with a remainder of 186.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtract 401 from 587 to get 186.
Include the next digit (0) from the dividend after 186, then repeat: 1860 / 401

Step 4:
If we divide 1860 by 401, we get 4 and a remainder of 256.
The next digit of our result is 4. 
Result so far: 14.0
The remainder is 256 after subtracting 1604 from 1860.
Bring next digit (9) of the dividend behind the 256 and repeat the process: 2569 / 401

Going ahead to step 5:
2569 divided by 401 is 6 with a remainder of 163.
Write down 6 as next digit of the result. 
Result so far: 146.0
If we take 2406 away from 2569, we end up with 163.
Append the next digit (2) from the dividend to 163 and continue with: 1632 / 401

Step 6:
401 goes into 1632 4 times with a remainder of 28.
The number 4 becomes the next digit in our result. 
Result so far: 1464.0
Subtracting 1604 from 1632 leaves us with 28.
Include the next digit (4) from the dividend after 28, then repeat: 284 / 401

Let's proceed to step 7:
The number 401 fits into 284 0 times, leaving a remainder of 284.
Write down 0 as next digit of the result. 
Result so far: 14640.0
Subtract 0 from 284 to get 284.
Append the next digit (0) from the dividend to 284 and continue with: 2840 / 401

Moving on to step 8:
The number 401 fits into 2840 7 times, leaving a remainder of 33.
The next digit of our result is 7. 
Result so far: 146407.0
Subtract 2807 from 2840 to get 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

On to step 9:
401 goes into 330 0 times with a remainder of 330.
Put 0 as the next digit of the answer. 
Result so far: 146407.0
Subtracting 0 from 330 leaves us with 330.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3300, and continue the process.

Let's proceed to step 10:
If we divide 3300 by 401, we get 8 and a remainder of 92.
Write down 8 as next digit of the result. 
Result so far: 146407.08
Subtracting 3208 from 3300 leaves us with 92.
Since there are no more digits in the dividend, we add a zero to the remainder making it 920, and continue the process.

On to step 11:
920 divided by 401 is 2 with a remainder of 118.
Put 2 as the next digit of the answer. 
Result so far: 146407.082
If we subtract 802 from 920, we get 118.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1180, and continue the process.

On to step 12:
401 can be fit into 1180 2 times, resulting in a remainder of 378.
Record the quotient 2 as the next digit in the result. 
Result so far: 146407.0822
Subtracting 802 from 1180 leaves us with 378.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3780, and continue the process.

Our division results in 146407.0822 with a remaining 0.00378.
