We divide 17410737 by 401
The aim is to understand the frequency of 401 in 17410737.

Step 1:
1 divided by 401 is 0 with a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Bring next digit (7) of the dividend behind the 1 and repeat the process: 17 / 401

Step 2:
The number 401 fits into 17 0 times, leaving a remainder of 17.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 17, we get 17.
Append the next digit (4) from the dividend to 17 and continue with: 174 / 401

Let's proceed to step 3:
401 can be fit into 174 0 times, resulting in a remainder of 174.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 174, we get 174.
Fetch the next digit (1) from the dividend, attach it to 174 and continue: 1741 / 401

Advancing to step 4:
401 can be fit into 1741 4 times, resulting in a remainder of 137.
Write down 4 as next digit of the result. 
Result so far: 4.0
If we take 1604 away from 1741, we end up with 137.
Take the next digit (0) from the dividend and append it to 137, then repeat: 1370 / 401

Step 5:
401 goes into 1370 3 times with a remainder of 167.
Record the quotient 3 as the next digit in the result. 
Result so far: 43.0
Subtracting 1203 from 1370 leaves us with 167.
Append the next digit (7) from the dividend to 167 and continue with: 1677 / 401

Step 6:
401 goes into 1677 4 times with a remainder of 73.
Write down 4 as next digit of the result. 
Result so far: 434.0
Deduct 1604 from 1677 and we're left with 73.
Bring next digit (3) of the dividend behind the 73 and repeat the process: 733 / 401

Advancing to step 7:
The number 401 fits into 733 1 times, leaving a remainder of 332.
The next digit of our result is 1. 
Result so far: 4341.0
If we subtract 401 from 733, we get 332.
Grab the next digit (7) from the dividend, add it to 332, then carry on: 3327 / 401

Step 8:
401 goes into 3327 8 times with a remainder of 119.
Use 8 as the next digit of our solution. 
Result so far: 43418.0
Subtracting 3208 from 3327 leaves us with 119.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1190, and continue the process.

Moving on to step 9:
401 can be fit into 1190 2 times, resulting in a remainder of 388.
Write down 2 as next digit of the result. 
Result so far: 43418.2
Subtract 802 from 1190 to get 388.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3880, and continue the process.

Advancing to step 10:
The number 401 fits into 3880 9 times, leaving a remainder of 271.
Put 9 as the next digit of the answer. 
Result so far: 43418.29
The remainder is 271 after subtracting 3609 from 3880.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2710, and continue the process.

Let's proceed to step 11:
401 goes into 2710 6 times with a remainder of 304.
Put 6 as the next digit of the answer. 
Result so far: 43418.296
Subtract 2406 from 2710 to get 304.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3040, and continue the process.

Advancing to step 12:
401 can be fit into 3040 7 times, resulting in a remainder of 233.
Write down 7 as next digit of the result. 
Result so far: 43418.2967
Subtracting 2807 from 3040 leaves us with 233.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2330, and continue the process.

On to step 13:
401 goes into 2330 5 times with a remainder of 325.
Write down 5 as next digit of the result. 
Result so far: 43418.29675
Subtracting 2005 from 2330 leaves us with 325.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3250, and continue the process.

Step 14:
401 goes into 3250 8 times with a remainder of 42.
Use 8 as the next digit of our solution. 
Result so far: 43418.296758
Subtracting 3208 from 3250 leaves us with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Going ahead to step 15:
420 divided by 401 is 1 with a remainder of 19.
Record the quotient 1 as the next digit in the result. 
Result so far: 43418.2967581
If we take 401 away from 420, we end up with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Going ahead to step 16:
The number 401 fits into 190 0 times, leaving a remainder of 190.
The number 0 becomes the next digit in our result. 
Result so far: 43418.2967581
Subtract 0 from 190 to get 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1900, and continue the process.

The final outcome is 43418.2967581, with a leftover of 1.9e-07.
