15129691 ÷ 153 
The aim is to understand the frequency of 153 in 15129691.

Going ahead to step 1:
153 can be fit into 1 0 times, resulting in a remainder of 1.
The number 0 becomes the next digit in our result. 
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 / 153

Let's proceed to step 2:
When dividing 15 by 153, we get 0 with a remainder of 15.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 15 leaves us with 15.
Fetch the next digit (1) from the dividend, attach it to 15 and continue: 151 / 153

On to step 3:
When dividing 151 by 153, we get 0 with a remainder of 151.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 151 after subtracting 0 from 151.
Include the next digit (2) from the dividend after 151, then repeat: 1512 / 153

Going ahead to step 4:
The number 153 fits into 1512 9 times, leaving a remainder of 135.
Put 9 as the next digit of the answer. 
Result so far: 9.0
The remainder is 135 after subtracting 1377 from 1512.
Include the next digit (9) from the dividend after 135, then repeat: 1359 / 153

On to step 5:
153 goes into 1359 8 times with a remainder of 135.
Put 8 as the next digit of the answer. 
Result so far: 98.0
Subtract 1224 from 1359 to get 135.
Take the next digit (6) from the dividend and append it to 135, then repeat: 1356 / 153

On to step 6:
153 can be fit into 1356 8 times, resulting in a remainder of 132.
Record the quotient 8 as the next digit in the result. 
Result so far: 988.0
If we subtract 1224 from 1356, we get 132.
Fetch the next digit (9) from the dividend, attach it to 132 and continue: 1329 / 153

Advancing to step 7:
153 can be fit into 1329 8 times, resulting in a remainder of 105.
Write down 8 as next digit of the result. 
Result so far: 9888.0
If we subtract 1224 from 1329, we get 105.
Append the next digit (1) from the dividend to 105 and continue with: 1051 / 153

Step 8:
When dividing 1051 by 153, we get 6 with a remainder of 133.
Write down 6 as next digit of the result. 
Result so far: 98886.0
Deduct 918 from 1051 and we're left with 133.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1330, and continue the process.

Step 9:
The number 153 fits into 1330 8 times, leaving a remainder of 106.
Put 8 as the next digit of the answer. 
Result so far: 98886.8
If we subtract 1224 from 1330, 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.

Step 10:
153 goes into 1060 6 times with a remainder of 142.
Write down 6 as next digit of the result. 
Result so far: 98886.86
If we subtract 918 from 1060, we get 142.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1420, and continue the process.

Let's proceed to step 11:
153 goes into 1420 9 times with a remainder of 43.
Put 9 as the next digit of the answer. 
Result so far: 98886.869
Subtracting 1377 from 1420 leaves us 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.

Going ahead to step 12:
153 can be fit into 430 2 times, resulting in a remainder of 124.
Put 2 as the next digit of the answer. 
Result so far: 98886.8692
If we take 306 away from 430, we end up with 124.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1240, and continue the process.

On to step 13:
153 goes into 1240 8 times with a remainder of 16.
The number 8 becomes the next digit in our result. 
Result so far: 98886.86928
Subtracting 1224 from 1240 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.

Let's proceed to step 14:
153 can be fit into 160 1 times, resulting in a remainder of 7.
Write down 1 as next digit of the result. 
Result so far: 98886.869281
If we subtract 153 from 160, we get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Let's proceed to step 15:
153 goes into 70 0 times with a remainder of 70.
The number 0 becomes the next digit in our result. 
Result so far: 98886.869281
The remainder is 70 after subtracting 0 from 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

On to step 16:
153 can be fit into 700 4 times, resulting in a remainder of 88.
Record the quotient 4 as the next digit in the result. 
Result so far: 98886.86928104
The remainder is 88 after subtracting 612 from 700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 880, and continue the process.

The final result is 98886.86928104 with a remainder of 8.8e-08.
