We divide 93975047 by 401
The aim is to understand the frequency of 401 in 93975047.

On to step 1:
When dividing 9 by 401, we get 0 with a remainder of 9.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 9, we end up with 9.
Fetch the next digit (3) from the dividend, attach it to 9 and continue: 93 / 401

Moving on to step 2:
401 goes into 93 0 times with a remainder of 93.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 93 leaves us with 93.
Append the next digit (9) from the dividend to 93 and continue with: 939 / 401

Moving on to step 3:
When dividing 939 by 401, we get 2 with a remainder of 137.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Subtract 802 from 939 to get 137.
Take the next digit (7) from the dividend and append it to 137, then repeat: 1377 / 401

Going ahead to step 4:
401 goes into 1377 3 times with a remainder of 174.
Put 3 as the next digit of the answer. 
Result so far: 23.0
If we take 1203 away from 1377, we end up with 174.
Bring next digit (5) of the dividend behind the 174 and repeat the process: 1745 / 401

Step 5:
The number 401 fits into 1745 4 times, leaving a remainder of 141.
Record the quotient 4 as the next digit in the result. 
Result so far: 234.0
The remainder is 141 after subtracting 1604 from 1745.
Take the next digit (0) from the dividend and append it to 141, then repeat: 1410 / 401

Going ahead to step 6:
If we divide 1410 by 401, we get 3 and a remainder of 207.
The next digit of our result is 3. 
Result so far: 2343.0
If we subtract 1203 from 1410, we get 207.
Grab the next digit (4) from the dividend, add it to 207, then carry on: 2074 / 401

Moving on to step 7:
When dividing 2074 by 401, we get 5 with a remainder of 69.
The next digit of our result is 5. 
Result so far: 23435.0
Subtract 2005 from 2074 to get 69.
Include the next digit (7) from the dividend after 69, then repeat: 697 / 401

On to step 8:
The number 401 fits into 697 1 times, leaving a remainder of 296.
The next digit of our result is 1. 
Result so far: 234351.0
Subtracting 401 from 697 leaves us with 296.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2960, and continue the process.

Going ahead to step 9:
401 can be fit into 2960 7 times, resulting in a remainder of 153.
The number 7 becomes the next digit in our result. 
Result so far: 234351.7
If we subtract 2807 from 2960, we get 153.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1530, and continue the process.

Step 10:
If we divide 1530 by 401, we get 3 and a remainder of 327.
The number 3 becomes the next digit in our result. 
Result so far: 234351.73
Subtracting 1203 from 1530 leaves us with 327.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3270, and continue the process.

Advancing to step 11:
3270 divided by 401 is 8 with a remainder of 62.
The next digit of our result is 8. 
Result so far: 234351.738
If we subtract 3208 from 3270, we get 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Let's proceed to step 12:
401 goes into 620 1 times with a remainder of 219.
The next digit of our result is 1. 
Result so far: 234351.7381
If we subtract 401 from 620, we get 219.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2190, and continue the process.

Advancing to step 13:
401 goes into 2190 5 times with a remainder of 185.
The number 5 becomes the next digit in our result. 
Result so far: 234351.73815
Deduct 2005 from 2190 and we're left with 185.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1850, and continue the process.

On to step 14:
401 can be fit into 1850 4 times, resulting in a remainder of 246.
Put 4 as the next digit of the answer. 
Result so far: 234351.738154
Deduct 1604 from 1850 and we're left with 246.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2460, and continue the process.

Advancing to step 15:
401 goes into 2460 6 times with a remainder of 54.
Use 6 as the next digit of our solution. 
Result so far: 234351.7381546
The remainder is 54 after subtracting 2406 from 2460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Advancing to step 16:
401 can be fit into 540 1 times, resulting in a remainder of 139.
Write down 1 as next digit of the result. 
Result so far: 234351.73815461
The remainder is 139 after subtracting 401 from 540.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1390, and continue the process.

After the division, we end up with 234351.73815461 and a remainder of 1.39e-07.
