Let's divide 84950500 by 639
The aim is to understand the frequency of 639 in 84950500.

On to step 1:
8 divided by 639 is 0 with a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Bring next digit (4) of the dividend behind the 8 and repeat the process: 84 / 639

Advancing to step 2:
84 divided by 639 is 0 with a remainder of 84.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 84, we end up with 84.
Grab the next digit (9) from the dividend, add it to 84, then carry on: 849 / 639

On to step 3:
849 divided by 639 is 1 with a remainder of 210.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtracting 639 from 849 leaves us with 210.
Append the next digit (5) from the dividend to 210 and continue with: 2105 / 639

Advancing to step 4:
If we divide 2105 by 639, we get 3 and a remainder of 188.
Write down 3 as next digit of the result. 
Result so far: 13.0
If we take 1917 away from 2105, we end up with 188.
Include the next digit (0) from the dividend after 188, then repeat: 1880 / 639

On to step 5:
639 can be fit into 1880 2 times, resulting in a remainder of 602.
Record the quotient 2 as the next digit in the result. 
Result so far: 132.0
If we take 1278 away from 1880, we end up with 602.
Fetch the next digit (5) from the dividend, attach it to 602 and continue: 6025 / 639

On to step 6:
When dividing 6025 by 639, we get 9 with a remainder of 274.
Put 9 as the next digit of the answer. 
Result so far: 1329.0
Subtract 5751 from 6025 to get 274.
Fetch the next digit (0) from the dividend, attach it to 274 and continue: 2740 / 639

Going ahead to step 7:
When dividing 2740 by 639, we get 4 with a remainder of 184.
Record the quotient 4 as the next digit in the result. 
Result so far: 13294.0
Subtracting 2556 from 2740 leaves us with 184.
Grab the next digit (0) from the dividend, add it to 184, then carry on: 1840 / 639

Advancing to step 8:
1840 divided by 639 is 2 with a remainder of 562.
The next digit of our result is 2. 
Result so far: 132942.0
Subtract 1278 from 1840 to get 562.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5620, and continue the process.

Going ahead to step 9:
639 can be fit into 5620 8 times, resulting in a remainder of 508.
The next digit of our result is 8. 
Result so far: 132942.8
The remainder is 508 after subtracting 5112 from 5620.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5080, and continue the process.

Advancing to step 10:
5080 divided by 639 is 7 with a remainder of 607.
The number 7 becomes the next digit in our result. 
Result so far: 132942.87
Subtracting 4473 from 5080 leaves us with 607.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6070, and continue the process.

Going ahead to step 11:
6070 divided by 639 is 9 with a remainder of 319.
The number 9 becomes the next digit in our result. 
Result so far: 132942.879
If we subtract 5751 from 6070, we get 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 12:
639 can be fit into 3190 4 times, resulting in a remainder of 634.
The number 4 becomes the next digit in our result. 
Result so far: 132942.8794
Subtract 2556 from 3190 to get 634.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6340, and continue the process.

Going ahead to step 13:
If we divide 6340 by 639, we get 9 and a remainder of 589.
Write down 9 as next digit of the result. 
Result so far: 132942.87949
If we subtract 5751 from 6340, we get 589.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5890, and continue the process.

On to step 14:
The number 639 fits into 5890 9 times, leaving a remainder of 139.
Record the quotient 9 as the next digit in the result. 
Result so far: 132942.879499
Deduct 5751 from 5890 and we're left with 139.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1390, and continue the process.

Our division results in 132942.879499 with a remaining 1.39e-05.
