We're dividing 66614073 by 151 
The aim is to understand the frequency of 151 in 66614073.

On to step 1:
When dividing 6 by 151, we get 0 with a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Append the next digit (6) from the dividend to 6 and continue with: 66 / 151

Moving on to step 2:
151 goes into 66 0 times with a remainder of 66.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 66, we get 66.
Bring next digit (6) of the dividend behind the 66 and repeat the process: 666 / 151

Step 3:
If we divide 666 by 151, we get 4 and a remainder of 62.
Write down 4 as next digit of the result. 
Result so far: 4.0
The remainder is 62 after subtracting 604 from 666.
Take the next digit (1) from the dividend and append it to 62, then repeat: 621 / 151

Moving on to step 4:
151 goes into 621 4 times with a remainder of 17.
Record the quotient 4 as the next digit in the result. 
Result so far: 44.0
Subtract 604 from 621 to get 17.
Grab the next digit (4) from the dividend, add it to 17, then carry on: 174 / 151

Step 5:
151 can be fit into 174 1 times, resulting in a remainder of 23.
The next digit of our result is 1. 
Result so far: 441.0
The remainder is 23 after subtracting 151 from 174.
Bring next digit (0) of the dividend behind the 23 and repeat the process: 230 / 151

On to step 6:
The number 151 fits into 230 1 times, leaving a remainder of 79.
The next digit of our result is 1. 
Result so far: 4411.0
If we take 151 away from 230, we end up with 79.
Take the next digit (7) from the dividend and append it to 79, then repeat: 797 / 151

Going ahead to step 7:
151 goes into 797 5 times with a remainder of 42.
Record the quotient 5 as the next digit in the result. 
Result so far: 44115.0
The remainder is 42 after subtracting 755 from 797.
Grab the next digit (3) from the dividend, add it to 42, then carry on: 423 / 151

Moving on to step 8:
If we divide 423 by 151, we get 2 and a remainder of 121.
Write down 2 as next digit of the result. 
Result so far: 441152.0
The remainder is 121 after subtracting 302 from 423.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1210, and continue the process.

Going ahead to step 9:
1210 divided by 151 is 8 with a remainder of 2.
Record the quotient 8 as the next digit in the result. 
Result so far: 441152.8
If we take 1208 away from 1210, we end up with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

On to step 10:
The number 151 fits into 20 0 times, leaving a remainder of 20.
The number 0 becomes the next digit in our result. 
Result so far: 441152.8
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.

Step 11:
200 divided by 151 is 1 with a remainder of 49.
Put 1 as the next digit of the answer. 
Result so far: 441152.801
If we subtract 151 from 200, we get 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Moving on to step 12:
151 goes into 490 3 times with a remainder of 37.
The next digit of our result is 3. 
Result so far: 441152.8013
If we take 453 away from 490, we end up with 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Going ahead to step 13:
When dividing 370 by 151, we get 2 with a remainder of 68.
Record the quotient 2 as the next digit in the result. 
Result so far: 441152.80132
If we take 302 away from 370, we end up with 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Advancing to step 14:
151 can be fit into 680 4 times, resulting in a remainder of 76.
Record the quotient 4 as the next digit in the result. 
Result so far: 441152.801324
Subtract 604 from 680 to get 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Advancing to step 15:
151 can be fit into 760 5 times, resulting in a remainder of 5.
Write down 5 as next digit of the result. 
Result so far: 441152.8013245
Subtracting 755 from 760 leaves us with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

On to step 16:
50 divided by 151 is 0 with a remainder of 50.
The number 0 becomes the next digit in our result. 
Result so far: 441152.8013245
Subtract 0 from 50 to get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

After the division, we end up with 441152.8013245 and a remainder of 5e-08.
