Let's divide 3360574 by 156
The aim is to understand the frequency of 156 in 3360574.

Step 1:
When dividing 3 by 156, we get 0 with a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Grab the next digit (3) from the dividend, add it to 3, then carry on: 33 / 156

Let's proceed to step 2:
156 goes into 33 0 times with a remainder of 33.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 33, we end up with 33.
Grab the next digit (6) from the dividend, add it to 33, then carry on: 336 / 156

Step 3:
The number 156 fits into 336 2 times, leaving a remainder of 24.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Deduct 312 from 336 and we're left with 24.
Grab the next digit (0) from the dividend, add it to 24, then carry on: 240 / 156

Going ahead to step 4:
156 can be fit into 240 1 times, resulting in a remainder of 84.
Put 1 as the next digit of the answer. 
Result so far: 21.0
Deduct 156 from 240 and we're left with 84.
Grab the next digit (5) from the dividend, add it to 84, then carry on: 845 / 156

Going ahead to step 5:
When dividing 845 by 156, we get 5 with a remainder of 65.
The number 5 becomes the next digit in our result. 
Result so far: 215.0
If we take 780 away from 845, we end up with 65.
Grab the next digit (7) from the dividend, add it to 65, then carry on: 657 / 156

Moving on to step 6:
When dividing 657 by 156, we get 4 with a remainder of 33.
Record the quotient 4 as the next digit in the result. 
Result so far: 2154.0
Deduct 624 from 657 and we're left with 33.
Bring next digit (4) of the dividend behind the 33 and repeat the process: 334 / 156

Advancing to step 7:
156 goes into 334 2 times with a remainder of 22.
The number 2 becomes the next digit in our result. 
Result so far: 21542.0
The remainder is 22 after subtracting 312 from 334.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

On to step 8:
156 goes into 220 1 times with a remainder of 64.
Write down 1 as next digit of the result. 
Result so far: 21542.1
Subtract 156 from 220 to get 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Advancing to step 9:
The number 156 fits into 640 4 times, leaving a remainder of 16.
The next digit of our result is 4. 
Result so far: 21542.14
Subtracting 624 from 640 leaves us with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Moving on to step 10:
160 divided by 156 is 1 with a remainder of 4.
The next digit of our result is 1. 
Result so far: 21542.141
Subtract 156 from 160 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Going ahead to step 11:
40 divided by 156 is 0 with a remainder of 40.
Write down 0 as next digit of the result. 
Result so far: 21542.141
If we subtract 0 from 40, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Moving on to step 12:
The number 156 fits into 400 2 times, leaving a remainder of 88.
Put 2 as the next digit of the answer. 
Result so far: 21542.14102
Deduct 312 from 400 and we're left with 88.
Since there are no more digits in the dividend, we add a zero to the remainder making it 880, and continue the process.

Step 13:
If we divide 880 by 156, we get 5 and a remainder of 100.
The next digit of our result is 5. 
Result so far: 21542.141025
If we subtract 780 from 880, we get 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Step 14:
156 can be fit into 1000 6 times, resulting in a remainder of 64.
The number 6 becomes the next digit in our result. 
Result so far: 21542.1410256
Deduct 936 from 1000 and we're left with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Advancing to step 15:
156 can be fit into 640 4 times, resulting in a remainder of 16.
Put 4 as the next digit of the answer. 
Result so far: 21542.14102564
If we subtract 624 from 640, we get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

The final outcome is 21542.14102564, with a leftover of 1.6e-08.
