Let's divide 2133778 by 402
The aim is to understand the frequency of 402 in 2133778.

Step 1:
402 can be fit into 2 0 times, resulting in a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Append the next digit (1) from the dividend to 2 and continue with: 21 / 402

Advancing to step 2:
402 goes into 21 0 times with a remainder of 21.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 21, we get 21.
Bring next digit (3) of the dividend behind the 21 and repeat the process: 213 / 402

Step 3:
402 goes into 213 0 times with a remainder of 213.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 213 after subtracting 0 from 213.
Take the next digit (3) from the dividend and append it to 213, then repeat: 2133 / 402

Step 4:
2133 divided by 402 is 5 with a remainder of 123.
The next digit of our result is 5. 
Result so far: 5.0
The remainder is 123 after subtracting 2010 from 2133.
Grab the next digit (7) from the dividend, add it to 123, then carry on: 1237 / 402

On to step 5:
402 can be fit into 1237 3 times, resulting in a remainder of 31.
The number 3 becomes the next digit in our result. 
Result so far: 53.0
If we subtract 1206 from 1237, we get 31.
Grab the next digit (7) from the dividend, add it to 31, then carry on: 317 / 402

Going ahead to step 6:
If we divide 317 by 402, we get 0 and a remainder of 317.
Record the quotient 0 as the next digit in the result. 
Result so far: 530.0
Subtracting 0 from 317 leaves us with 317.
Grab the next digit (8) from the dividend, add it to 317, then carry on: 3178 / 402

Advancing to step 7:
When dividing 3178 by 402, we get 7 with a remainder of 364.
Record the quotient 7 as the next digit in the result. 
Result so far: 5307.0
If we subtract 2814 from 3178, we get 364.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3640, and continue the process.

Going ahead to step 8:
The number 402 fits into 3640 9 times, leaving a remainder of 22.
Use 9 as the next digit of our solution. 
Result so far: 5307.9
Deduct 3618 from 3640 and we're left with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Step 9:
220 divided by 402 is 0 with a remainder of 220.
The next digit of our result is 0. 
Result so far: 5307.9
Deduct 0 from 220 and we're left 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.

On to step 10:
When dividing 2200 by 402, we get 5 with a remainder of 190.
The next digit of our result is 5. 
Result so far: 5307.905
The remainder is 190 after subtracting 2010 from 2200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1900, and continue the process.

Let's proceed to step 11:
402 goes into 1900 4 times with a remainder of 292.
Put 4 as the next digit of the answer. 
Result so far: 5307.9054
Subtracting 1608 from 1900 leaves us with 292.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2920, and continue the process.

Step 12:
When dividing 2920 by 402, we get 7 with a remainder of 106.
The number 7 becomes the next digit in our result. 
Result so far: 5307.90547
If we subtract 2814 from 2920, we get 106.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1060, and continue the process.

Going ahead to step 13:
402 can be fit into 1060 2 times, resulting in a remainder of 256.
Use 2 as the next digit of our solution. 
Result so far: 5307.905472
Deduct 804 from 1060 and we're left with 256.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2560, and continue the process.

Moving on to step 14:
2560 divided by 402 is 6 with a remainder of 148.
Record the quotient 6 as the next digit in the result. 
Result so far: 5307.9054726
The remainder is 148 after subtracting 2412 from 2560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1480, and continue the process.

Going ahead to step 15:
1480 divided by 402 is 3 with a remainder of 274.
Use 3 as the next digit of our solution. 
Result so far: 5307.90547263
If we take 1206 away from 1480, we end up with 274.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2740, and continue the process.

The quotient of the division is 5307.90547263, and the remainder is 2.74e-07.
