We're dividing 55464887 by 668 
The aim is to understand the frequency of 668 in 55464887.

On to step 1:
5 divided by 668 is 0 with a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Append the next digit (5) from the dividend to 5 and continue with: 55 / 668

Moving on to step 2:
When dividing 55 by 668, we get 0 with a remainder of 55.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 55, we get 55.
Take the next digit (4) from the dividend and append it to 55, then repeat: 554 / 668

Let's proceed to step 3:
554 divided by 668 is 0 with a remainder of 554.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 554 leaves us with 554.
Fetch the next digit (6) from the dividend, attach it to 554 and continue: 5546 / 668

Going ahead to step 4:
The number 668 fits into 5546 8 times, leaving a remainder of 202.
The next digit of our result is 8. 
Result so far: 8.0
If we take 5344 away from 5546, we end up with 202.
Fetch the next digit (4) from the dividend, attach it to 202 and continue: 2024 / 668

Advancing to step 5:
668 can be fit into 2024 3 times, resulting in a remainder of 20.
Use 3 as the next digit of our solution. 
Result so far: 83.0
Deduct 2004 from 2024 and we're left with 20.
Bring next digit (8) of the dividend behind the 20 and repeat the process: 208 / 668

Let's proceed to step 6:
The number 668 fits into 208 0 times, leaving a remainder of 208.
The next digit of our result is 0. 
Result so far: 830.0
Subtract 0 from 208 to get 208.
Bring next digit (8) of the dividend behind the 208 and repeat the process: 2088 / 668

Advancing to step 7:
668 can be fit into 2088 3 times, resulting in a remainder of 84.
Write down 3 as next digit of the result. 
Result so far: 8303.0
If we take 2004 away from 2088, we end up with 84.
Include the next digit (7) from the dividend after 84, then repeat: 847 / 668

Advancing to step 8:
The number 668 fits into 847 1 times, leaving a remainder of 179.
The number 1 becomes the next digit in our result. 
Result so far: 83031.0
Subtract 668 from 847 to get 179.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1790, and continue the process.

Moving on to step 9:
The number 668 fits into 1790 2 times, leaving a remainder of 454.
Record the quotient 2 as the next digit in the result. 
Result so far: 83031.2
If we subtract 1336 from 1790, we get 454.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4540, and continue the process.

Advancing to step 10:
When dividing 4540 by 668, we get 6 with a remainder of 532.
The number 6 becomes the next digit in our result. 
Result so far: 83031.26
If we subtract 4008 from 4540, we get 532.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5320, and continue the process.

Advancing to step 11:
668 goes into 5320 7 times with a remainder of 644.
The number 7 becomes the next digit in our result. 
Result so far: 83031.267
If we take 4676 away from 5320, we end up with 644.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6440, and continue the process.

Going ahead to step 12:
The number 668 fits into 6440 9 times, leaving a remainder of 428.
Write down 9 as next digit of the result. 
Result so far: 83031.2679
Deduct 6012 from 6440 and we're left with 428.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4280, and continue the process.

On to step 13:
668 goes into 4280 6 times with a remainder of 272.
The next digit of our result is 6. 
Result so far: 83031.26796
If we take 4008 away from 4280, we end up with 272.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2720, and continue the process.

Let's proceed to step 14:
When dividing 2720 by 668, we get 4 with a remainder of 48.
Put 4 as the next digit of the answer. 
Result so far: 83031.267964
Subtract 2672 from 2720 to get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Advancing to step 15:
When dividing 480 by 668, we get 0 with a remainder of 480.
The number 0 becomes the next digit in our result. 
Result so far: 83031.267964
Subtracting 0 from 480 leaves us with 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4800, and continue the process.

On to step 16:
668 can be fit into 4800 7 times, resulting in a remainder of 124.
Write down 7 as next digit of the result. 
Result so far: 83031.26796407
If we take 4676 away from 4800, we end up with 124.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1240, and continue the process.

The final result is 83031.26796407 with a remainder of 1.24e-07.
