44285406 ÷ 639 
The aim is to understand the frequency of 639 in 44285406.

Going ahead to step 1:
639 goes into 4 0 times with a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Append the next digit (4) from the dividend to 4 and continue with: 44 / 639

On to step 2:
If we divide 44 by 639, we get 0 and a remainder of 44.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 44 after subtracting 0 from 44.
Fetch the next digit (2) from the dividend, attach it to 44 and continue: 442 / 639

Going ahead to step 3:
When dividing 442 by 639, we get 0 with a remainder of 442.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 442, we get 442.
Grab the next digit (8) from the dividend, add it to 442, then carry on: 4428 / 639

Moving on to step 4:
4428 divided by 639 is 6 with a remainder of 594.
Record the quotient 6 as the next digit in the result. 
Result so far: 6.0
If we subtract 3834 from 4428, we get 594.
Take the next digit (5) from the dividend and append it to 594, then repeat: 5945 / 639

On to step 5:
If we divide 5945 by 639, we get 9 and a remainder of 194.
Put 9 as the next digit of the answer. 
Result so far: 69.0
The remainder is 194 after subtracting 5751 from 5945.
Grab the next digit (4) from the dividend, add it to 194, then carry on: 1944 / 639

Let's proceed to step 6:
When dividing 1944 by 639, we get 3 with a remainder of 27.
The number 3 becomes the next digit in our result. 
Result so far: 693.0
Deduct 1917 from 1944 and we're left with 27.
Append the next digit (0) from the dividend to 27 and continue with: 270 / 639

Step 7:
270 divided by 639 is 0 with a remainder of 270.
The next digit of our result is 0. 
Result so far: 6930.0
If we subtract 0 from 270, we get 270.
Append the next digit (6) from the dividend to 270 and continue with: 2706 / 639

Step 8:
The number 639 fits into 2706 4 times, leaving a remainder of 150.
Use 4 as the next digit of our solution. 
Result so far: 69304.0
If we take 2556 away from 2706, we end up with 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

Going ahead to step 9:
When dividing 1500 by 639, we get 2 with a remainder of 222.
The next digit of our result is 2. 
Result so far: 69304.2
The remainder is 222 after subtracting 1278 from 1500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2220, and continue the process.

Let's proceed to step 10:
If we divide 2220 by 639, we get 3 and a remainder of 303.
Record the quotient 3 as the next digit in the result. 
Result so far: 69304.23
The remainder is 303 after subtracting 1917 from 2220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3030, and continue the process.

On to step 11:
When dividing 3030 by 639, we get 4 with a remainder of 474.
Record the quotient 4 as the next digit in the result. 
Result so far: 69304.234
Subtracting 2556 from 3030 leaves us with 474.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4740, and continue the process.

Step 12:
The number 639 fits into 4740 7 times, leaving a remainder of 267.
Use 7 as the next digit of our solution. 
Result so far: 69304.2347
Subtract 4473 from 4740 to get 267.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2670, and continue the process.

Moving on to step 13:
When dividing 2670 by 639, we get 4 with a remainder of 114.
Put 4 as the next digit of the answer. 
Result so far: 69304.23474
Subtract 2556 from 2670 to get 114.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1140, and continue the process.

Advancing to step 14:
639 goes into 1140 1 times with a remainder of 501.
Put 1 as the next digit of the answer. 
Result so far: 69304.234741
Subtract 639 from 1140 to get 501.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5010, and continue the process.

Moving on to step 15:
5010 divided by 639 is 7 with a remainder of 537.
The next digit of our result is 7. 
Result so far: 69304.2347417
Subtract 4473 from 5010 to get 537.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5370, and continue the process.

Let's proceed to step 16:
5370 divided by 639 is 8 with a remainder of 258.
Write down 8 as next digit of the result. 
Result so far: 69304.23474178
Subtracting 5112 from 5370 leaves us with 258.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2580, and continue the process.

The quotient of the division is 69304.23474178, and the remainder is 2.58e-07.
