63912113 ÷ 159 
The aim is to understand the frequency of 159 in 63912113.

Step 1:
When dividing 6 by 159, we get 0 with a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Bring next digit (3) of the dividend behind the 6 and repeat the process: 63 / 159

Moving on to step 2:
159 can be fit into 63 0 times, resulting in a remainder of 63.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 63, we get 63.
Include the next digit (9) from the dividend after 63, then repeat: 639 / 159

Advancing to step 3:
159 goes into 639 4 times with a remainder of 3.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
The remainder is 3 after subtracting 636 from 639.
Append the next digit (1) from the dividend to 3 and continue with: 31 / 159

Moving on to step 4:
If we divide 31 by 159, we get 0 and a remainder of 31.
The next digit of our result is 0. 
Result so far: 40.0
If we take 0 away from 31, we end up with 31.
Append the next digit (2) from the dividend to 31 and continue with: 312 / 159

Going ahead to step 5:
312 divided by 159 is 1 with a remainder of 153.
The number 1 becomes the next digit in our result. 
Result so far: 401.0
Subtracting 159 from 312 leaves us with 153.
Append the next digit (1) from the dividend to 153 and continue with: 1531 / 159

Moving on to step 6:
If we divide 1531 by 159, we get 9 and a remainder of 100.
Write down 9 as next digit of the result. 
Result so far: 4019.0
Subtracting 1431 from 1531 leaves us with 100.
Append the next digit (1) from the dividend to 100 and continue with: 1001 / 159

Step 7:
When dividing 1001 by 159, we get 6 with a remainder of 47.
The next digit of our result is 6. 
Result so far: 40196.0
If we take 954 away from 1001, we end up with 47.
Include the next digit (3) from the dividend after 47, then repeat: 473 / 159

Advancing to step 8:
159 can be fit into 473 2 times, resulting in a remainder of 155.
The number 2 becomes the next digit in our result. 
Result so far: 401962.0
Subtract 318 from 473 to get 155.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1550, and continue the process.

Step 9:
159 goes into 1550 9 times with a remainder of 119.
Use 9 as the next digit of our solution. 
Result so far: 401962.9
Deduct 1431 from 1550 and we're left with 119.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1190, and continue the process.

On to step 10:
If we divide 1190 by 159, we get 7 and a remainder of 77.
Use 7 as the next digit of our solution. 
Result so far: 401962.97
The remainder is 77 after subtracting 1113 from 1190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 770, and continue the process.

Step 11:
159 can be fit into 770 4 times, resulting in a remainder of 134.
Put 4 as the next digit of the answer. 
Result so far: 401962.974
If we take 636 away from 770, we end up with 134.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1340, and continue the process.

Moving on to step 12:
If we divide 1340 by 159, we get 8 and a remainder of 68.
The next digit of our result is 8. 
Result so far: 401962.9748
The remainder is 68 after subtracting 1272 from 1340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Let's proceed to step 13:
When dividing 680 by 159, we get 4 with a remainder of 44.
The number 4 becomes the next digit in our result. 
Result so far: 401962.97484
If we subtract 636 from 680, we get 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Moving on to step 14:
440 divided by 159 is 2 with a remainder of 122.
Record the quotient 2 as the next digit in the result. 
Result so far: 401962.974842
If we subtract 318 from 440, we get 122.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1220, and continue the process.

Step 15:
The number 159 fits into 1220 7 times, leaving a remainder of 107.
The number 7 becomes the next digit in our result. 
Result so far: 401962.9748427
If we subtract 1113 from 1220, we get 107.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1070, and continue the process.

Let's proceed to step 16:
1070 divided by 159 is 6 with a remainder of 116.
Put 6 as the next digit of the answer. 
Result so far: 401962.97484276
Deduct 954 from 1070 and we're left with 116.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1160, and continue the process.

The quotient of the division is 401962.97484276, and the remainder is 1.16e-07.
