23577537 divided by 401 
The aim is to understand the frequency of 401 in 23577537.

Advancing to step 1:
If we divide 2 by 401, we get 0 and a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Grab the next digit (3) from the dividend, add it to 2, then carry on: 23 / 401

Advancing to step 2:
401 goes into 23 0 times with a remainder of 23.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 23, we end up with 23.
Append the next digit (5) from the dividend to 23 and continue with: 235 / 401

On to step 3:
401 goes into 235 0 times with a remainder of 235.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 235, we get 235.
Fetch the next digit (7) from the dividend, attach it to 235 and continue: 2357 / 401

Moving on to step 4:
401 goes into 2357 5 times with a remainder of 352.
The number 5 becomes the next digit in our result. 
Result so far: 5.0
Subtracting 2005 from 2357 leaves us with 352.
Grab the next digit (7) from the dividend, add it to 352, then carry on: 3527 / 401

Step 5:
If we divide 3527 by 401, we get 8 and a remainder of 319.
Put 8 as the next digit of the answer. 
Result so far: 58.0
Subtract 3208 from 3527 to get 319.
Append the next digit (5) from the dividend to 319 and continue with: 3195 / 401

Let's proceed to step 6:
The number 401 fits into 3195 7 times, leaving a remainder of 388.
The next digit of our result is 7. 
Result so far: 587.0
The remainder is 388 after subtracting 2807 from 3195.
Include the next digit (3) from the dividend after 388, then repeat: 3883 / 401

Let's proceed to step 7:
When dividing 3883 by 401, we get 9 with a remainder of 274.
Put 9 as the next digit of the answer. 
Result so far: 5879.0
Deduct 3609 from 3883 and we're left with 274.
Include the next digit (7) from the dividend after 274, then repeat: 2747 / 401

On to step 8:
401 can be fit into 2747 6 times, resulting in a remainder of 341.
Write down 6 as next digit of the result. 
Result so far: 58796.0
If we take 2406 away from 2747, we end up with 341.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3410, and continue the process.

On to step 9:
The number 401 fits into 3410 8 times, leaving a remainder of 202.
Put 8 as the next digit of the answer. 
Result so far: 58796.8
The remainder is 202 after subtracting 3208 from 3410.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2020, and continue the process.

Moving on to step 10:
If we divide 2020 by 401, we get 5 and a remainder of 15.
The number 5 becomes the next digit in our result. 
Result so far: 58796.85
Subtracting 2005 from 2020 leaves us with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Moving on to step 11:
If we divide 150 by 401, we get 0 and a remainder of 150.
Use 0 as the next digit of our solution. 
Result so far: 58796.85
Deduct 0 from 150 and we're left with 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

Going ahead to step 12:
If we divide 1500 by 401, we get 3 and a remainder of 297.
Record the quotient 3 as the next digit in the result. 
Result so far: 58796.8503
If we subtract 1203 from 1500, we get 297.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2970, and continue the process.

Moving on to step 13:
If we divide 2970 by 401, we get 7 and a remainder of 163.
The number 7 becomes the next digit in our result. 
Result so far: 58796.85037
Subtracting 2807 from 2970 leaves us with 163.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1630, and continue the process.

Going ahead to step 14:
401 goes into 1630 4 times with a remainder of 26.
Use 4 as the next digit of our solution. 
Result so far: 58796.850374
If we subtract 1604 from 1630, we get 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Advancing to step 15:
If we divide 260 by 401, we get 0 and a remainder of 260.
Record the quotient 0 as the next digit in the result. 
Result so far: 58796.850374
If we take 0 away from 260, we end up with 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2600, and continue the process.

Let's proceed to step 16:
When dividing 2600 by 401, we get 6 with a remainder of 194.
Use 6 as the next digit of our solution. 
Result so far: 58796.85037406
Subtracting 2406 from 2600 leaves us with 194.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1940, and continue the process.

The final outcome is 58796.85037406, with a leftover of 1.94e-07.
