We're dividing 37970794 by 668 
The aim is to understand the frequency of 668 in 37970794.

Going ahead to step 1:
The number 668 fits into 3 0 times, leaving a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Append the next digit (7) from the dividend to 3 and continue with: 37 / 668

Moving on to step 2:
668 goes into 37 0 times with a remainder of 37.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 37 after subtracting 0 from 37.
Include the next digit (9) from the dividend after 37, then repeat: 379 / 668

On to step 3:
379 divided by 668 is 0 with a remainder of 379.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 379, we end up with 379.
Bring next digit (7) of the dividend behind the 379 and repeat the process: 3797 / 668

Step 4:
668 goes into 3797 5 times with a remainder of 457.
Put 5 as the next digit of the answer. 
Result so far: 5.0
Deduct 3340 from 3797 and we're left with 457.
Bring next digit (0) of the dividend behind the 457 and repeat the process: 4570 / 668

Let's proceed to step 5:
If we divide 4570 by 668, we get 6 and a remainder of 562.
Write down 6 as next digit of the result. 
Result so far: 56.0
Subtract 4008 from 4570 to get 562.
Bring next digit (7) of the dividend behind the 562 and repeat the process: 5627 / 668

Going ahead to step 6:
When dividing 5627 by 668, we get 8 with a remainder of 283.
Use 8 as the next digit of our solution. 
Result so far: 568.0
The remainder is 283 after subtracting 5344 from 5627.
Fetch the next digit (9) from the dividend, attach it to 283 and continue: 2839 / 668

Going ahead to step 7:
668 goes into 2839 4 times with a remainder of 167.
The number 4 becomes the next digit in our result. 
Result so far: 5684.0
Subtract 2672 from 2839 to get 167.
Include the next digit (4) from the dividend after 167, then repeat: 1674 / 668

Going ahead to step 8:
If we divide 1674 by 668, we get 2 and a remainder of 338.
Write down 2 as next digit of the result. 
Result so far: 56842.0
Subtract 1336 from 1674 to get 338.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3380, and continue the process.

Advancing to step 9:
3380 divided by 668 is 5 with a remainder of 40.
Put 5 as the next digit of the answer. 
Result so far: 56842.5
The remainder is 40 after subtracting 3340 from 3380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Moving on to step 10:
When dividing 400 by 668, we get 0 with a remainder of 400.
The next digit of our result is 0. 
Result so far: 56842.5
Subtracting 0 from 400 leaves us with 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

Step 11:
When dividing 4000 by 668, we get 5 with a remainder of 660.
Use 5 as the next digit of our solution. 
Result so far: 56842.505
Subtracting 3340 from 4000 leaves us with 660.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6600, and continue the process.

Advancing to step 12:
The number 668 fits into 6600 9 times, leaving a remainder of 588.
The number 9 becomes the next digit in our result. 
Result so far: 56842.5059
If we subtract 6012 from 6600, we get 588.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5880, and continue the process.

Step 13:
5880 divided by 668 is 8 with a remainder of 536.
Use 8 as the next digit of our solution. 
Result so far: 56842.50598
Subtract 5344 from 5880 to get 536.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5360, and continue the process.

Moving on to step 14:
668 goes into 5360 8 times with a remainder of 16.
Use 8 as the next digit of our solution. 
Result so far: 56842.505988
Subtracting 5344 from 5360 leaves us 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.

The final outcome is 56842.505988, with a leftover of 1.6e-06.
