We divide 42845986 by 639
The aim is to understand the frequency of 639 in 42845986.

Let's proceed to step 1:
If we divide 4 by 639, we get 0 and a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Bring next digit (2) of the dividend behind the 4 and repeat the process: 42 / 639

Let's proceed to step 2:
639 can be fit into 42 0 times, resulting in a remainder of 42.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 42 and we're left with 42.
Bring next digit (8) of the dividend behind the 42 and repeat the process: 428 / 639

Advancing to step 3:
428 divided by 639 is 0 with a remainder of 428.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 428, we get 428.
Fetch the next digit (4) from the dividend, attach it to 428 and continue: 4284 / 639

Advancing to step 4:
639 goes into 4284 6 times with a remainder of 450.
Record the quotient 6 as the next digit in the result. 
Result so far: 6.0
Subtracting 3834 from 4284 leaves us with 450.
Fetch the next digit (5) from the dividend, attach it to 450 and continue: 4505 / 639

Going ahead to step 5:
If we divide 4505 by 639, we get 7 and a remainder of 32.
The next digit of our result is 7. 
Result so far: 67.0
If we take 4473 away from 4505, we end up with 32.
Append the next digit (9) from the dividend to 32 and continue with: 329 / 639

Going ahead to step 6:
639 goes into 329 0 times with a remainder of 329.
The number 0 becomes the next digit in our result. 
Result so far: 670.0
Subtracting 0 from 329 leaves us with 329.
Include the next digit (8) from the dividend after 329, then repeat: 3298 / 639

Step 7:
639 can be fit into 3298 5 times, resulting in a remainder of 103.
The next digit of our result is 5. 
Result so far: 6705.0
If we take 3195 away from 3298, we end up with 103.
Append the next digit (6) from the dividend to 103 and continue with: 1036 / 639

Step 8:
639 goes into 1036 1 times with a remainder of 397.
Write down 1 as next digit of the result. 
Result so far: 67051.0
Deduct 639 from 1036 and we're left with 397.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3970, and continue the process.

Advancing to step 9:
The number 639 fits into 3970 6 times, leaving a remainder of 136.
Use 6 as the next digit of our solution. 
Result so far: 67051.6
Deduct 3834 from 3970 and we're left with 136.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1360, and continue the process.

Step 10:
1360 divided by 639 is 2 with a remainder of 82.
Write down 2 as next digit of the result. 
Result so far: 67051.62
Deduct 1278 from 1360 and we're left with 82.
Since there are no more digits in the dividend, we add a zero to the remainder making it 820, and continue the process.

On to step 11:
The number 639 fits into 820 1 times, leaving a remainder of 181.
Put 1 as the next digit of the answer. 
Result so far: 67051.621
If we subtract 639 from 820, we get 181.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1810, and continue the process.

Moving on to step 12:
If we divide 1810 by 639, we get 2 and a remainder of 532.
The number 2 becomes the next digit in our result. 
Result so far: 67051.6212
If we take 1278 away from 1810, we end up with 532.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5320, and continue the process.

Going ahead to step 13:
639 can be fit into 5320 8 times, resulting in a remainder of 208.
Write down 8 as next digit of the result. 
Result so far: 67051.62128
Subtract 5112 from 5320 to 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.

Going ahead to step 14:
639 goes into 2080 3 times with a remainder of 163.
Record the quotient 3 as the next digit in the result. 
Result so far: 67051.621283
Deduct 1917 from 2080 and we're left with 163.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1630, and continue the process.

Step 15:
The number 639 fits into 1630 2 times, leaving a remainder of 352.
The number 2 becomes the next digit in our result. 
Result so far: 67051.6212832
If we subtract 1278 from 1630, we get 352.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3520, and continue the process.

Moving on to step 16:
639 goes into 3520 5 times with a remainder of 325.
The number 5 becomes the next digit in our result. 
Result so far: 67051.62128325
Subtract 3195 from 3520 to get 325.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3250, and continue the process.

Our division results in 67051.62128325 with a remaining 3.25e-07.
