We're dividing 36519703 by 669 
The aim is to understand the frequency of 669 in 36519703.

Step 1:
The number 669 fits into 3 0 times, leaving a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Fetch the next digit (6) from the dividend, attach it to 3 and continue: 36 / 669

Let's proceed to step 2:
669 goes into 36 0 times with a remainder of 36.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 36 to get 36.
Grab the next digit (5) from the dividend, add it to 36, then carry on: 365 / 669

Advancing to step 3:
669 can be fit into 365 0 times, resulting in a remainder of 365.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 365, we end up with 365.
Bring next digit (1) of the dividend behind the 365 and repeat the process: 3651 / 669

Step 4:
669 goes into 3651 5 times with a remainder of 306.
The next digit of our result is 5. 
Result so far: 5.0
The remainder is 306 after subtracting 3345 from 3651.
Append the next digit (9) from the dividend to 306 and continue with: 3069 / 669

Moving on to step 5:
The number 669 fits into 3069 4 times, leaving a remainder of 393.
Use 4 as the next digit of our solution. 
Result so far: 54.0
Deduct 2676 from 3069 and we're left with 393.
Grab the next digit (7) from the dividend, add it to 393, then carry on: 3937 / 669

Advancing to step 6:
When dividing 3937 by 669, we get 5 with a remainder of 592.
The next digit of our result is 5. 
Result so far: 545.0
The remainder is 592 after subtracting 3345 from 3937.
Bring next digit (0) of the dividend behind the 592 and repeat the process: 5920 / 669

Step 7:
669 can be fit into 5920 8 times, resulting in a remainder of 568.
Put 8 as the next digit of the answer. 
Result so far: 5458.0
The remainder is 568 after subtracting 5352 from 5920.
Grab the next digit (3) from the dividend, add it to 568, then carry on: 5683 / 669

Advancing to step 8:
If we divide 5683 by 669, we get 8 and a remainder of 331.
Put 8 as the next digit of the answer. 
Result so far: 54588.0
Subtract 5352 from 5683 to get 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 9:
The number 669 fits into 3310 4 times, leaving a remainder of 634.
Write down 4 as next digit of the result. 
Result so far: 54588.4
Deduct 2676 from 3310 and we're left with 634.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6340, and continue the process.

Moving on to step 10:
669 goes into 6340 9 times with a remainder of 319.
Record the quotient 9 as the next digit in the result. 
Result so far: 54588.49
If we take 6021 away from 6340, we end up with 319.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3190, and continue the process.

Let's proceed to step 11:
669 can be fit into 3190 4 times, resulting in a remainder of 514.
Write down 4 as next digit of the result. 
Result so far: 54588.494
Deduct 2676 from 3190 and we're left with 514.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5140, and continue the process.

Advancing to step 12:
The number 669 fits into 5140 7 times, leaving a remainder of 457.
The number 7 becomes the next digit in our result. 
Result so far: 54588.4947
Subtracting 4683 from 5140 leaves us with 457.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4570, and continue the process.

Moving on to step 13:
The number 669 fits into 4570 6 times, leaving a remainder of 556.
Write down 6 as next digit of the result. 
Result so far: 54588.49476
The remainder is 556 after subtracting 4014 from 4570.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5560, and continue the process.

Advancing to step 14:
If we divide 5560 by 669, we get 8 and a remainder of 208.
Use 8 as the next digit of our solution. 
Result so far: 54588.494768
If we subtract 5352 from 5560, we get 208.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2080, and continue the process.

Let's proceed to step 15:
When dividing 2080 by 669, we get 3 with a remainder of 73.
Use 3 as the next digit of our solution. 
Result so far: 54588.4947683
The remainder is 73 after subtracting 2007 from 2080.
Since there are no more digits in the dividend, we add a zero to the remainder making it 730, and continue the process.

Advancing to step 16:
669 goes into 730 1 times with a remainder of 61.
The number 1 becomes the next digit in our result. 
Result so far: 54588.49476831
Deduct 669 from 730 and we're left with 61.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

The quotient of the division is 54588.49476831, and the remainder is 6.1e-08.
