12120730 divided by 158 
The aim is to understand the frequency of 158 in 12120730.

Step 1:
158 goes into 1 0 times with a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Take the next digit (2) from the dividend and append it to 1, then repeat: 12 / 158

Advancing to step 2:
158 goes into 12 0 times with a remainder of 12.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 12 and we're left with 12.
Take the next digit (1) from the dividend and append it to 12, then repeat: 121 / 158

Going ahead to step 3:
158 goes into 121 0 times with a remainder of 121.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 121, we get 121.
Bring next digit (2) of the dividend behind the 121 and repeat the process: 1212 / 158

Advancing to step 4:
1212 divided by 158 is 7 with a remainder of 106.
The number 7 becomes the next digit in our result. 
Result so far: 7.0
Subtracting 1106 from 1212 leaves us with 106.
Bring next digit (0) of the dividend behind the 106 and repeat the process: 1060 / 158

Going ahead to step 5:
158 goes into 1060 6 times with a remainder of 112.
The next digit of our result is 6. 
Result so far: 76.0
If we take 948 away from 1060, we end up with 112.
Append the next digit (7) from the dividend to 112 and continue with: 1127 / 158

Advancing to step 6:
If we divide 1127 by 158, we get 7 and a remainder of 21.
The next digit of our result is 7. 
Result so far: 767.0
Subtract 1106 from 1127 to get 21.
Grab the next digit (3) from the dividend, add it to 21, then carry on: 213 / 158

Moving on to step 7:
158 goes into 213 1 times with a remainder of 55.
Write down 1 as next digit of the result. 
Result so far: 7671.0
If we take 158 away from 213, we end up with 55.
Bring next digit (0) of the dividend behind the 55 and repeat the process: 550 / 158

On to step 8:
If we divide 550 by 158, we get 3 and a remainder of 76.
Put 3 as the next digit of the answer. 
Result so far: 76713.0
Subtracting 474 from 550 leaves us with 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

On to step 9:
When dividing 760 by 158, we get 4 with a remainder of 128.
Put 4 as the next digit of the answer. 
Result so far: 76713.4
Subtracting 632 from 760 leaves us with 128.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1280, and continue the process.

Step 10:
When dividing 1280 by 158, we get 8 with a remainder of 16.
The next digit of our result is 8. 
Result so far: 76713.48
If we take 1264 away from 1280, we end up 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.

Going ahead to step 11:
If we divide 160 by 158, we get 1 and a remainder of 2.
Write down 1 as next digit of the result. 
Result so far: 76713.481
The remainder is 2 after subtracting 158 from 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Moving on to step 12:
20 divided by 158 is 0 with a remainder of 20.
Put 0 as the next digit of the answer. 
Result so far: 76713.481
Subtracting 0 from 20 leaves us with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Moving on to step 13:
When dividing 200 by 158, we get 1 with a remainder of 42.
Put 1 as the next digit of the answer. 
Result so far: 76713.48101
Subtract 158 from 200 to get 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Advancing to step 14:
158 goes into 420 2 times with a remainder of 104.
Record the quotient 2 as the next digit in the result. 
Result so far: 76713.481012
The remainder is 104 after subtracting 316 from 420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1040, and continue the process.

Let's proceed to step 15:
When dividing 1040 by 158, we get 6 with a remainder of 92.
Use 6 as the next digit of our solution. 
Result so far: 76713.4810126
Deduct 948 from 1040 and we're left with 92.
Since there are no more digits in the dividend, we add a zero to the remainder making it 920, and continue the process.

Going ahead to step 16:
158 can be fit into 920 5 times, resulting in a remainder of 130.
The next digit of our result is 5. 
Result so far: 76713.48101265
Subtract 790 from 920 to get 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

Our division results in 76713.48101265 with a remaining 1.3e-07.
