We look at the division of 44847878 by 661 
The aim is to understand the frequency of 661 in 44847878.

Advancing to step 1:
661 goes into 4 0 times with a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Fetch the next digit (4) from the dividend, attach it to 4 and continue: 44 / 661

Let's proceed to step 2:
The number 661 fits into 44 0 times, leaving a remainder of 44.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 44 to get 44.
Grab the next digit (8) from the dividend, add it to 44, then carry on: 448 / 661

Moving on to step 3:
When dividing 448 by 661, we get 0 with a remainder of 448.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 448, we end up with 448.
Take the next digit (4) from the dividend and append it to 448, then repeat: 4484 / 661

Advancing to step 4:
661 can be fit into 4484 6 times, resulting in a remainder of 518.
The next digit of our result is 6. 
Result so far: 6.0
If we subtract 3966 from 4484, we get 518.
Grab the next digit (7) from the dividend, add it to 518, then carry on: 5187 / 661

Let's proceed to step 5:
5187 divided by 661 is 7 with a remainder of 560.
The number 7 becomes the next digit in our result. 
Result so far: 67.0
Subtracting 4627 from 5187 leaves us with 560.
Take the next digit (8) from the dividend and append it to 560, then repeat: 5608 / 661

Step 6:
661 can be fit into 5608 8 times, resulting in a remainder of 320.
Record the quotient 8 as the next digit in the result. 
Result so far: 678.0
Subtract 5288 from 5608 to get 320.
Include the next digit (7) from the dividend after 320, then repeat: 3207 / 661

Moving on to step 7:
661 can be fit into 3207 4 times, resulting in a remainder of 563.
Record the quotient 4 as the next digit in the result. 
Result so far: 6784.0
If we subtract 2644 from 3207, we get 563.
Bring next digit (8) of the dividend behind the 563 and repeat the process: 5638 / 661

On to step 8:
661 can be fit into 5638 8 times, resulting in a remainder of 350.
Put 8 as the next digit of the answer. 
Result so far: 67848.0
If we take 5288 away from 5638, we end up with 350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3500, and continue the process.

Going ahead to step 9:
661 can be fit into 3500 5 times, resulting in a remainder of 195.
Record the quotient 5 as the next digit in the result. 
Result so far: 67848.5
If we take 3305 away from 3500, we end up with 195.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1950, and continue the process.

Advancing to step 10:
1950 divided by 661 is 2 with a remainder of 628.
Put 2 as the next digit of the answer. 
Result so far: 67848.52
If we subtract 1322 from 1950, we get 628.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6280, and continue the process.

Moving on to step 11:
The number 661 fits into 6280 9 times, leaving a remainder of 331.
Record the quotient 9 as the next digit in the result. 
Result so far: 67848.529
Deduct 5949 from 6280 and we're left with 331.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3310, and continue the process.

Advancing to step 12:
When dividing 3310 by 661, we get 5 with a remainder of 5.
Use 5 as the next digit of our solution. 
Result so far: 67848.5295
If we subtract 3305 from 3310, we get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Moving on to step 13:
661 goes into 50 0 times with a remainder of 50.
Put 0 as the next digit of the answer. 
Result so far: 67848.5295
If we take 0 away from 50, we end up with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Moving on to step 14:
When dividing 500 by 661, we get 0 with a remainder of 500.
The number 0 becomes the next digit in our result. 
Result so far: 67848.5295
If we subtract 0 from 500, we get 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5000, and continue the process.

The final outcome is 67848.5295, with a leftover of 5e-05.
