Let's divide 15862437 by 668
The aim is to understand the frequency of 668 in 15862437.

On to step 1:
The number 668 fits into 1 0 times, leaving a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Include the next digit (5) from the dividend after 1, then repeat: 15 / 668

Advancing to step 2:
When dividing 15 by 668, we get 0 with a remainder of 15.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 15 and we're left with 15.
Take the next digit (8) from the dividend and append it to 15, then repeat: 158 / 668

Step 3:
668 goes into 158 0 times with a remainder of 158.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 158, we end up with 158.
Bring next digit (6) of the dividend behind the 158 and repeat the process: 1586 / 668

On to step 4:
668 can be fit into 1586 2 times, resulting in a remainder of 250.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
If we subtract 1336 from 1586, we get 250.
Take the next digit (2) from the dividend and append it to 250, then repeat: 2502 / 668

Going ahead to step 5:
If we divide 2502 by 668, we get 3 and a remainder of 498.
Put 3 as the next digit of the answer. 
Result so far: 23.0
If we subtract 2004 from 2502, we get 498.
Include the next digit (4) from the dividend after 498, then repeat: 4984 / 668

Going ahead to step 6:
When dividing 4984 by 668, we get 7 with a remainder of 308.
Put 7 as the next digit of the answer. 
Result so far: 237.0
Subtract 4676 from 4984 to get 308.
Bring next digit (3) of the dividend behind the 308 and repeat the process: 3083 / 668

Step 7:
If we divide 3083 by 668, we get 4 and a remainder of 411.
Put 4 as the next digit of the answer. 
Result so far: 2374.0
If we take 2672 away from 3083, we end up with 411.
Fetch the next digit (7) from the dividend, attach it to 411 and continue: 4117 / 668

Going ahead to step 8:
If we divide 4117 by 668, we get 6 and a remainder of 109.
Use 6 as the next digit of our solution. 
Result so far: 23746.0
Deduct 4008 from 4117 and we're left with 109.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1090, and continue the process.

Let's proceed to step 9:
If we divide 1090 by 668, we get 1 and a remainder of 422.
Write down 1 as next digit of the result. 
Result so far: 23746.1
The remainder is 422 after subtracting 668 from 1090.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4220, and continue the process.

Let's proceed to step 10:
4220 divided by 668 is 6 with a remainder of 212.
Record the quotient 6 as the next digit in the result. 
Result so far: 23746.16
Subtract 4008 from 4220 to get 212.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2120, and continue the process.

Advancing to step 11:
The number 668 fits into 2120 3 times, leaving a remainder of 116.
Record the quotient 3 as the next digit in the result. 
Result so far: 23746.163
If we take 2004 away from 2120, we end up 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.

Advancing to step 12:
The number 668 fits into 1160 1 times, leaving a remainder of 492.
The next digit of our result is 1. 
Result so far: 23746.1631
If we take 668 away from 1160, we end up with 492.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4920, and continue the process.

Moving on to step 13:
When dividing 4920 by 668, we get 7 with a remainder of 244.
The next digit of our result is 7. 
Result so far: 23746.16317
Subtract 4676 from 4920 to get 244.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2440, and continue the process.

Advancing to step 14:
The number 668 fits into 2440 3 times, leaving a remainder of 436.
Put 3 as the next digit of the answer. 
Result so far: 23746.163173
If we subtract 2004 from 2440, we get 436.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4360, and continue the process.

Going ahead to step 15:
The number 668 fits into 4360 6 times, leaving a remainder of 352.
The number 6 becomes the next digit in our result. 
Result so far: 23746.1631736
If we take 4008 away from 4360, we end up with 352.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3520, and continue the process.

Advancing to step 16:
3520 divided by 668 is 5 with a remainder of 180.
Write down 5 as next digit of the result. 
Result so far: 23746.16317365
Subtract 3340 from 3520 to get 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

In conclusion, the division gives 23746.16317365 with a balance of 1.8e-07.
