28601634 ÷ 156 
The aim is to understand the frequency of 156 in 28601634.

On to step 1:
If we divide 2 by 156, we get 0 and a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Include the next digit (8) from the dividend after 2, then repeat: 28 / 156

Step 2:
156 goes into 28 0 times with a remainder of 28.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 28, we end up with 28.
Append the next digit (6) from the dividend to 28 and continue with: 286 / 156

Going ahead to step 3:
The number 156 fits into 286 1 times, leaving a remainder of 130.
Put 1 as the next digit of the answer. 
Result so far: 1.0
The remainder is 130 after subtracting 156 from 286.
Take the next digit (0) from the dividend and append it to 130, then repeat: 1300 / 156

On to step 4:
The number 156 fits into 1300 8 times, leaving a remainder of 52.
Record the quotient 8 as the next digit in the result. 
Result so far: 18.0
If we subtract 1248 from 1300, we get 52.
Grab the next digit (1) from the dividend, add it to 52, then carry on: 521 / 156

On to step 5:
156 goes into 521 3 times with a remainder of 53.
Record the quotient 3 as the next digit in the result. 
Result so far: 183.0
If we subtract 468 from 521, we get 53.
Append the next digit (6) from the dividend to 53 and continue with: 536 / 156

Moving on to step 6:
If we divide 536 by 156, we get 3 and a remainder of 68.
Use 3 as the next digit of our solution. 
Result so far: 1833.0
Deduct 468 from 536 and we're left with 68.
Include the next digit (3) from the dividend after 68, then repeat: 683 / 156

Moving on to step 7:
156 goes into 683 4 times with a remainder of 59.
The number 4 becomes the next digit in our result. 
Result so far: 18334.0
If we take 624 away from 683, we end up with 59.
Grab the next digit (4) from the dividend, add it to 59, then carry on: 594 / 156

Moving on to step 8:
156 can be fit into 594 3 times, resulting in a remainder of 126.
The number 3 becomes the next digit in our result. 
Result so far: 183343.0
Subtract 468 from 594 to get 126.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1260, and continue the process.

Let's proceed to step 9:
1260 divided by 156 is 8 with a remainder of 12.
Record the quotient 8 as the next digit in the result. 
Result so far: 183343.8
If we take 1248 away from 1260, we end up with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Moving on to step 10:
The number 156 fits into 120 0 times, leaving a remainder of 120.
Put 0 as the next digit of the answer. 
Result so far: 183343.8
If we subtract 0 from 120, we get 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

On to step 11:
The number 156 fits into 1200 7 times, leaving a remainder of 108.
Write down 7 as next digit of the result. 
Result so far: 183343.807
The remainder is 108 after subtracting 1092 from 1200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1080, and continue the process.

Moving on to step 12:
When dividing 1080 by 156, we get 6 with a remainder of 144.
Put 6 as the next digit of the answer. 
Result so far: 183343.8076
If we subtract 936 from 1080, we get 144.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1440, and continue the process.

Step 13:
1440 divided by 156 is 9 with a remainder of 36.
The next digit of our result is 9. 
Result so far: 183343.80769
Deduct 1404 from 1440 and we're left with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Going ahead to step 14:
If we divide 360 by 156, we get 2 and a remainder of 48.
Use 2 as the next digit of our solution. 
Result so far: 183343.807692
If we subtract 312 from 360, we get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Advancing to step 15:
156 can be fit into 480 3 times, resulting in a remainder of 12.
Use 3 as the next digit of our solution. 
Result so far: 183343.8076923
Subtracting 468 from 480 leaves us with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Step 16:
If we divide 120 by 156, we get 0 and a remainder of 120.
The number 0 becomes the next digit in our result. 
Result so far: 183343.8076923
Subtract 0 from 120 to get 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

The final outcome is 183343.8076923, with a leftover of 1.2e-07.
