We're dividing 15886771 by 156 
The aim is to understand the frequency of 156 in 15886771.

On to step 1:
1 divided by 156 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.
Take the next digit (5) from the dividend and append it to 1, then repeat: 15 / 156

On to step 2:
15 divided by 156 is 0 with a remainder of 15.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 15, we get 15.
Append the next digit (8) from the dividend to 15 and continue with: 158 / 156

On to step 3:
The number 156 fits into 158 1 times, leaving a remainder of 2.
Write down 1 as next digit of the result. 
Result so far: 1.0
The remainder is 2 after subtracting 156 from 158.
Take the next digit (8) from the dividend and append it to 2, then repeat: 28 / 156

Step 4:
156 can be fit into 28 0 times, resulting in a remainder of 28.
Put 0 as the next digit of the answer. 
Result so far: 10.0
Subtracting 0 from 28 leaves us with 28.
Bring next digit (6) of the dividend behind the 28 and repeat the process: 286 / 156

Moving on to step 5:
286 divided by 156 is 1 with a remainder of 130.
The next digit of our result is 1. 
Result so far: 101.0
The remainder is 130 after subtracting 156 from 286.
Append the next digit (7) from the dividend to 130 and continue with: 1307 / 156

Going ahead to step 6:
156 goes into 1307 8 times with a remainder of 59.
Write down 8 as next digit of the result. 
Result so far: 1018.0
The remainder is 59 after subtracting 1248 from 1307.
Append the next digit (7) from the dividend to 59 and continue with: 597 / 156

Moving on to step 7:
When dividing 597 by 156, we get 3 with a remainder of 129.
Use 3 as the next digit of our solution. 
Result so far: 10183.0
If we take 468 away from 597, we end up with 129.
Include the next digit (1) from the dividend after 129, then repeat: 1291 / 156

Step 8:
If we divide 1291 by 156, we get 8 and a remainder of 43.
Write down 8 as next digit of the result. 
Result so far: 101838.0
Deduct 1248 from 1291 and we're left with 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Advancing to step 9:
156 goes into 430 2 times with a remainder of 118.
The next digit of our result is 2. 
Result so far: 101838.2
Deduct 312 from 430 and we're left with 118.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1180, and continue the process.

Let's proceed to step 10:
The number 156 fits into 1180 7 times, leaving a remainder of 88.
The number 7 becomes the next digit in our result. 
Result so far: 101838.27
Subtract 1092 from 1180 to get 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 11:
When dividing 880 by 156, we get 5 with a remainder of 100.
Record the quotient 5 as the next digit in the result. 
Result so far: 101838.275
The remainder is 100 after subtracting 780 from 880.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

On to step 12:
When dividing 1000 by 156, we get 6 with a remainder of 64.
The next digit of our result is 6. 
Result so far: 101838.2756
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.

Going ahead to step 13:
If we divide 640 by 156, we get 4 and a remainder of 16.
The next digit of our result is 4. 
Result so far: 101838.27564
Subtract 624 from 640 to 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.

Advancing to step 14:
The number 156 fits into 160 1 times, leaving a remainder of 4.
Put 1 as the next digit of the answer. 
Result so far: 101838.275641
Deduct 156 from 160 and we're left with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

On to step 15:
The number 156 fits into 40 0 times, leaving a remainder of 40.
Put 0 as the next digit of the answer. 
Result so far: 101838.275641
If we take 0 away from 40, we end up with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Let's proceed to step 16:
400 divided by 156 is 2 with a remainder of 88.
The number 2 becomes the next digit in our result. 
Result so far: 101838.27564102
Subtract 312 from 400 to get 88.
Since there are no more digits in the dividend, we add a zero to the remainder making it 880, and continue the process.

The quotient of the division is 101838.27564102, and the remainder is 8.8e-08.
