11853453 divided by 158 
The aim is to understand the frequency of 158 in 11853453.

Step 1:
If we divide 1 by 158, we get 0 and a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Append the next digit (1) from the dividend to 1 and continue with: 11 / 158

Moving on to step 2:
11 divided by 158 is 0 with a remainder of 11.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 11, we end up with 11.
Bring next digit (8) of the dividend behind the 11 and repeat the process: 118 / 158

Let's proceed to step 3:
If we divide 118 by 158, we get 0 and a remainder of 118.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 118 to get 118.
Grab the next digit (5) from the dividend, add it to 118, then carry on: 1185 / 158

On to step 4:
158 goes into 1185 7 times with a remainder of 79.
Write down 7 as next digit of the result. 
Result so far: 7.0
Subtract 1106 from 1185 to get 79.
Include the next digit (3) from the dividend after 79, then repeat: 793 / 158

Moving on to step 5:
When dividing 793 by 158, we get 5 with a remainder of 3.
The number 5 becomes the next digit in our result. 
Result so far: 75.0
The remainder is 3 after subtracting 790 from 793.
Bring next digit (4) of the dividend behind the 3 and repeat the process: 34 / 158

Moving on to step 6:
34 divided by 158 is 0 with a remainder of 34.
Write down 0 as next digit of the result. 
Result so far: 750.0
Deduct 0 from 34 and we're left with 34.
Fetch the next digit (5) from the dividend, attach it to 34 and continue: 345 / 158

Going ahead to step 7:
345 divided by 158 is 2 with a remainder of 29.
Use 2 as the next digit of our solution. 
Result so far: 7502.0
If we take 316 away from 345, we end up with 29.
Append the next digit (3) from the dividend to 29 and continue with: 293 / 158

Let's proceed to step 8:
158 goes into 293 1 times with a remainder of 135.
Use 1 as the next digit of our solution. 
Result so far: 75021.0
If we take 158 away from 293, we end up with 135.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1350, and continue the process.

Moving on to step 9:
1350 divided by 158 is 8 with a remainder of 86.
Record the quotient 8 as the next digit in the result. 
Result so far: 75021.8
If we take 1264 away from 1350, we end up with 86.
Since there are no more digits in the dividend, we add a zero to the remainder making it 860, and continue the process.

Advancing to step 10:
158 can be fit into 860 5 times, resulting in a remainder of 70.
Put 5 as the next digit of the answer. 
Result so far: 75021.85
Subtracting 790 from 860 leaves us with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Going ahead to step 11:
158 goes into 700 4 times with a remainder of 68.
Put 4 as the next digit of the answer. 
Result so far: 75021.854
If we subtract 632 from 700, we get 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Step 12:
680 divided by 158 is 4 with a remainder of 48.
Write down 4 as next digit of the result. 
Result so far: 75021.8544
The remainder is 48 after subtracting 632 from 680.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

The quotient of the division is 75021.8544, and the remainder is 0.00048.
