401994 divided by 52 
The aim is to understand the frequency of 52 in 401994.

Going ahead to step 1:
When dividing 4 by 52, we get 0 with a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Fetch the next digit (0) from the dividend, attach it to 4 and continue: 40 / 52

Step 2:
52 can be fit into 40 0 times, resulting in a remainder of 40.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 40 after subtracting 0 from 40.
Fetch the next digit (1) from the dividend, attach it to 40 and continue: 401 / 52

Advancing to step 3:
When dividing 401 by 52, we get 7 with a remainder of 37.
Use 7 as the next digit of our solution. 
Result so far: 7.0
The remainder is 37 after subtracting 364 from 401.
Bring next digit (9) of the dividend behind the 37 and repeat the process: 379 / 52

On to step 4:
If we divide 379 by 52, we get 7 and a remainder of 15.
Put 7 as the next digit of the answer. 
Result so far: 77.0
The remainder is 15 after subtracting 364 from 379.
Append the next digit (9) from the dividend to 15 and continue with: 159 / 52

Advancing to step 5:
159 divided by 52 is 3 with a remainder of 3.
The next digit of our result is 3. 
Result so far: 773.0
If we take 156 away from 159, we end up with 3.
Grab the next digit (4) from the dividend, add it to 3, then carry on: 34 / 52

Let's proceed to step 6:
52 goes into 34 0 times with a remainder of 34.
Put 0 as the next digit of the answer. 
Result so far: 7730.0
Deduct 0 from 34 and we're left with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Going ahead to step 7:
340 divided by 52 is 6 with a remainder of 28.
The number 6 becomes the next digit in our result. 
Result so far: 7730.6
The remainder is 28 after subtracting 312 from 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

On to step 8:
52 goes into 280 5 times with a remainder of 20.
Put 5 as the next digit of the answer. 
Result so far: 7730.65
Deduct 260 from 280 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Going ahead to step 9:
200 divided by 52 is 3 with a remainder of 44.
Record the quotient 3 as the next digit in the result. 
Result so far: 7730.653
Subtract 156 from 200 to get 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Advancing to step 10:
52 can be fit into 440 8 times, resulting in a remainder of 24.
The next digit of our result is 8. 
Result so far: 7730.6538
The remainder is 24 after subtracting 416 from 440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Advancing to step 11:
52 goes into 240 4 times with a remainder of 32.
Record the quotient 4 as the next digit in the result. 
Result so far: 7730.65384
Subtracting 208 from 240 leaves us with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Moving on to step 12:
If we divide 320 by 52, we get 6 and a remainder of 8.
The next digit of our result is 6. 
Result so far: 7730.653846
If we subtract 312 from 320, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Step 13:
When dividing 80 by 52, we get 1 with a remainder of 28.
Write down 1 as next digit of the result. 
Result so far: 7730.6538461
If we subtract 52 from 80, we get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

On to step 14:
If we divide 280 by 52, we get 5 and a remainder of 20.
The next digit of our result is 5. 
Result so far: 7730.65384615
If we take 260 away from 280, we end up with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

The quotient of the division is 7730.65384615, and the remainder is 2e-08.
