We look at the division of 37840209 by 159 
The aim is to understand the frequency of 159 in 37840209.

Moving on to step 1:
If we divide 3 by 159, we get 0 and a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Take the next digit (7) from the dividend and append it to 3, then repeat: 37 / 159

On to step 2:
If we divide 37 by 159, we get 0 and a remainder of 37.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 37 and we're left with 37.
Append the next digit (8) from the dividend to 37 and continue with: 378 / 159

Let's proceed to step 3:
If we divide 378 by 159, we get 2 and a remainder of 60.
The next digit of our result is 2. 
Result so far: 2.0
Deduct 318 from 378 and we're left with 60.
Fetch the next digit (4) from the dividend, attach it to 60 and continue: 604 / 159

On to step 4:
159 goes into 604 3 times with a remainder of 127.
Use 3 as the next digit of our solution. 
Result so far: 23.0
If we take 477 away from 604, we end up with 127.
Bring next digit (0) of the dividend behind the 127 and repeat the process: 1270 / 159

Step 5:
The number 159 fits into 1270 7 times, leaving a remainder of 157.
Use 7 as the next digit of our solution. 
Result so far: 237.0
Subtract 1113 from 1270 to get 157.
Grab the next digit (2) from the dividend, add it to 157, then carry on: 1572 / 159

Let's proceed to step 6:
159 goes into 1572 9 times with a remainder of 141.
Record the quotient 9 as the next digit in the result. 
Result so far: 2379.0
Deduct 1431 from 1572 and we're left with 141.
Grab the next digit (0) from the dividend, add it to 141, then carry on: 1410 / 159

Going ahead to step 7:
The number 159 fits into 1410 8 times, leaving a remainder of 138.
Put 8 as the next digit of the answer. 
Result so far: 23798.0
Subtracting 1272 from 1410 leaves us with 138.
Bring next digit (9) of the dividend behind the 138 and repeat the process: 1389 / 159

Step 8:
159 goes into 1389 8 times with a remainder of 117.
Record the quotient 8 as the next digit in the result. 
Result so far: 237988.0
Deduct 1272 from 1389 and we're left with 117.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1170, and continue the process.

Let's proceed to step 9:
159 can be fit into 1170 7 times, resulting in a remainder of 57.
Write down 7 as next digit of the result. 
Result so far: 237988.7
If we subtract 1113 from 1170, we get 57.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

On to step 10:
When dividing 570 by 159, we get 3 with a remainder of 93.
Use 3 as the next digit of our solution. 
Result so far: 237988.73
Deduct 477 from 570 and we're left with 93.
Since there are no more digits in the dividend, we add a zero to the remainder making it 930, and continue the process.

Step 11:
If we divide 930 by 159, we get 5 and a remainder of 135.
Record the quotient 5 as the next digit in the result. 
Result so far: 237988.735
Deduct 795 from 930 and we're left 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.

Let's proceed to step 12:
1350 divided by 159 is 8 with a remainder of 78.
Put 8 as the next digit of the answer. 
Result so far: 237988.7358
Deduct 1272 from 1350 and we're left with 78.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

On to step 13:
159 goes into 780 4 times with a remainder of 144.
Use 4 as the next digit of our solution. 
Result so far: 237988.73584
Subtract 636 from 780 to 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.

On to step 14:
1440 divided by 159 is 9 with a remainder of 9.
The number 9 becomes the next digit in our result. 
Result so far: 237988.735849
Subtracting 1431 from 1440 leaves us with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

On to step 15:
159 can be fit into 90 0 times, resulting in a remainder of 90.
The next digit of our result is 0. 
Result so far: 237988.735849
Deduct 0 from 90 and we're left with 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

Step 16:
If we divide 900 by 159, we get 5 and a remainder of 105.
Put 5 as the next digit of the answer. 
Result so far: 237988.73584905
If we take 795 away from 900, we end up with 105.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1050, and continue the process.

The quotient of the division is 237988.73584905, and the remainder is 1.05e-07.
