Let's divide 20003937 by 926
The aim is to understand the frequency of 926 in 20003937.

On to step 1:
926 can be fit into 2 0 times, resulting in a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Grab the next digit (0) from the dividend, add it to 2, then carry on: 20 / 926

Moving on to step 2:
When dividing 20 by 926, we get 0 with a remainder of 20.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 20 and we're left with 20.
Include the next digit (0) from the dividend after 20, then repeat: 200 / 926

Advancing to step 3:
The number 926 fits into 200 0 times, leaving a remainder of 200.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 200 and we're left with 200.
Append the next digit (0) from the dividend to 200 and continue with: 2000 / 926

Advancing to step 4:
The number 926 fits into 2000 2 times, leaving a remainder of 148.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Deduct 1852 from 2000 and we're left with 148.
Take the next digit (3) from the dividend and append it to 148, then repeat: 1483 / 926

Step 5:
1483 divided by 926 is 1 with a remainder of 557.
Put 1 as the next digit of the answer. 
Result so far: 21.0
Subtract 926 from 1483 to get 557.
Grab the next digit (9) from the dividend, add it to 557, then carry on: 5579 / 926

Step 6:
The number 926 fits into 5579 6 times, leaving a remainder of 23.
The number 6 becomes the next digit in our result. 
Result so far: 216.0
Subtract 5556 from 5579 to get 23.
Include the next digit (3) from the dividend after 23, then repeat: 233 / 926

On to step 7:
233 divided by 926 is 0 with a remainder of 233.
The next digit of our result is 0. 
Result so far: 2160.0
If we subtract 0 from 233, we get 233.
Take the next digit (7) from the dividend and append it to 233, then repeat: 2337 / 926

On to step 8:
The number 926 fits into 2337 2 times, leaving a remainder of 485.
Use 2 as the next digit of our solution. 
Result so far: 21602.0
Subtract 1852 from 2337 to get 485.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4850, and continue the process.

Step 9:
If we divide 4850 by 926, we get 5 and a remainder of 220.
The number 5 becomes the next digit in our result. 
Result so far: 21602.5
If we take 4630 away from 4850, we end up with 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2200, and continue the process.

Moving on to step 10:
When dividing 2200 by 926, we get 2 with a remainder of 348.
The next digit of our result is 2. 
Result so far: 21602.52
Subtracting 1852 from 2200 leaves us with 348.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3480, and continue the process.

Going ahead to step 11:
When dividing 3480 by 926, we get 3 with a remainder of 702.
Use 3 as the next digit of our solution. 
Result so far: 21602.523
Deduct 2778 from 3480 and we're left with 702.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7020, and continue the process.

Step 12:
926 goes into 7020 7 times with a remainder of 538.
Write down 7 as next digit of the result. 
Result so far: 21602.5237
Subtracting 6482 from 7020 leaves us with 538.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5380, and continue the process.

Going ahead to step 13:
5380 divided by 926 is 5 with a remainder of 750.
The number 5 becomes the next digit in our result. 
Result so far: 21602.52375
Deduct 4630 from 5380 and we're left with 750.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7500, and continue the process.

Let's proceed to step 14:
When dividing 7500 by 926, we get 8 with a remainder of 92.
Record the quotient 8 as the next digit in the result. 
Result so far: 21602.523758
The remainder is 92 after subtracting 7408 from 7500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 920, and continue the process.

Advancing to step 15:
926 can be fit into 920 0 times, resulting in a remainder of 920.
The number 0 becomes the next digit in our result. 
Result so far: 21602.523758
Subtracting 0 from 920 leaves us with 920.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9200, and continue the process.

Let's proceed to step 16:
9200 divided by 926 is 9 with a remainder of 866.
Write down 9 as next digit of the result. 
Result so far: 21602.52375809
If we take 8334 away from 9200, we end up with 866.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8660, and continue the process.

The final outcome is 21602.52375809, with a leftover of 8.66e-07.
