Let's divide 73119868 by 661
The aim is to understand the frequency of 661 in 73119868.

Step 1:
661 goes into 7 0 times with a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Take the next digit (3) from the dividend and append it to 7, then repeat: 73 / 661

Going ahead to step 2:
73 divided by 661 is 0 with a remainder of 73.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 73 and we're left with 73.
Include the next digit (1) from the dividend after 73, then repeat: 731 / 661

Advancing to step 3:
The number 661 fits into 731 1 times, leaving a remainder of 70.
Write down 1 as next digit of the result. 
Result so far: 1.0
Deduct 661 from 731 and we're left with 70.
Append the next digit (1) from the dividend to 70 and continue with: 701 / 661

Moving on to step 4:
If we divide 701 by 661, we get 1 and a remainder of 40.
The number 1 becomes the next digit in our result. 
Result so far: 11.0
Deduct 661 from 701 and we're left with 40.
Take the next digit (9) from the dividend and append it to 40, then repeat: 409 / 661

Step 5:
409 divided by 661 is 0 with a remainder of 409.
Use 0 as the next digit of our solution. 
Result so far: 110.0
If we subtract 0 from 409, we get 409.
Include the next digit (8) from the dividend after 409, then repeat: 4098 / 661

Advancing to step 6:
4098 divided by 661 is 6 with a remainder of 132.
Use 6 as the next digit of our solution. 
Result so far: 1106.0
Deduct 3966 from 4098 and we're left with 132.
Fetch the next digit (6) from the dividend, attach it to 132 and continue: 1326 / 661

Step 7:
661 goes into 1326 2 times with a remainder of 4.
The next digit of our result is 2. 
Result so far: 11062.0
If we subtract 1322 from 1326, we get 4.
Append the next digit (8) from the dividend to 4 and continue with: 48 / 661

Moving on to step 8:
The number 661 fits into 48 0 times, leaving a remainder of 48.
Write down 0 as next digit of the result. 
Result so far: 110620.0
If we subtract 0 from 48, we 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 9:
When dividing 480 by 661, we get 0 with a remainder of 480.
Use 0 as the next digit of our solution. 
Result so far: 110620.0
If we subtract 0 from 480, we get 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4800, and continue the process.

Moving on to step 10:
The number 661 fits into 4800 7 times, leaving a remainder of 173.
Record the quotient 7 as the next digit in the result. 
Result so far: 110620.07
If we subtract 4627 from 4800, we get 173.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1730, and continue the process.

Let's proceed to step 11:
The number 661 fits into 1730 2 times, leaving a remainder of 408.
Record the quotient 2 as the next digit in the result. 
Result so far: 110620.072
Deduct 1322 from 1730 and we're left with 408.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4080, and continue the process.

On to step 12:
4080 divided by 661 is 6 with a remainder of 114.
The next digit of our result is 6. 
Result so far: 110620.0726
The remainder is 114 after subtracting 3966 from 4080.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1140, and continue the process.

On to step 13:
661 goes into 1140 1 times with a remainder of 479.
Record the quotient 1 as the next digit in the result. 
Result so far: 110620.07261
If we subtract 661 from 1140, we get 479.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4790, and continue the process.

On to step 14:
If we divide 4790 by 661, we get 7 and a remainder of 163.
Use 7 as the next digit of our solution. 
Result so far: 110620.072617
Subtract 4627 from 4790 to get 163.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1630, and continue the process.

Moving on to step 15:
1630 divided by 661 is 2 with a remainder of 308.
The number 2 becomes the next digit in our result. 
Result so far: 110620.0726172
If we subtract 1322 from 1630, we get 308.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3080, and continue the process.

Moving on to step 16:
The number 661 fits into 3080 4 times, leaving a remainder of 436.
Write down 4 as next digit of the result. 
Result so far: 110620.07261724
If we take 2644 away from 3080, we end up with 436.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4360, and continue the process.

Our division results in 110620.07261724 with a remaining 4.36e-07.
