We divide 73237638 by 639
The aim is to understand the frequency of 639 in 73237638.

Let's proceed to step 1:
639 can be fit into 7 0 times, resulting in a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Append the next digit (3) from the dividend to 7 and continue with: 73 / 639

On to step 2:
639 can be fit into 73 0 times, resulting in a remainder of 73.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 73 to get 73.
Append the next digit (2) from the dividend to 73 and continue with: 732 / 639

Let's proceed to step 3:
639 goes into 732 1 times with a remainder of 93.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we subtract 639 from 732, we get 93.
Append the next digit (3) from the dividend to 93 and continue with: 933 / 639

Moving on to step 4:
933 divided by 639 is 1 with a remainder of 294.
Use 1 as the next digit of our solution. 
Result so far: 11.0
Subtracting 639 from 933 leaves us with 294.
Include the next digit (7) from the dividend after 294, then repeat: 2947 / 639

Step 5:
When dividing 2947 by 639, we get 4 with a remainder of 391.
Use 4 as the next digit of our solution. 
Result so far: 114.0
Deduct 2556 from 2947 and we're left with 391.
Bring next digit (6) of the dividend behind the 391 and repeat the process: 3916 / 639

Step 6:
If we divide 3916 by 639, we get 6 and a remainder of 82.
Use 6 as the next digit of our solution. 
Result so far: 1146.0
Deduct 3834 from 3916 and we're left with 82.
Take the next digit (3) from the dividend and append it to 82, then repeat: 823 / 639

On to step 7:
If we divide 823 by 639, we get 1 and a remainder of 184.
The number 1 becomes the next digit in our result. 
Result so far: 11461.0
Deduct 639 from 823 and we're left with 184.
Take the next digit (8) from the dividend and append it to 184, then repeat: 1848 / 639

Advancing to step 8:
639 can be fit into 1848 2 times, resulting in a remainder of 570.
The next digit of our result is 2. 
Result so far: 114612.0
If we subtract 1278 from 1848, we get 570.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5700, and continue the process.

Step 9:
639 goes into 5700 8 times with a remainder of 588.
Write down 8 as next digit of the result. 
Result so far: 114612.8
If we take 5112 away from 5700, we end up with 588.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5880, and continue the process.

Advancing to step 10:
5880 divided by 639 is 9 with a remainder of 129.
Write down 9 as next digit of the result. 
Result so far: 114612.89
If we take 5751 away from 5880, we end up with 129.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1290, and continue the process.

Moving on to step 11:
When dividing 1290 by 639, we get 2 with a remainder of 12.
The next digit of our result is 2. 
Result so far: 114612.892
Subtract 1278 from 1290 to get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Let's proceed to step 12:
639 can be fit into 120 0 times, resulting in a remainder of 120.
Use 0 as the next digit of our solution. 
Result so far: 114612.892
The remainder is 120 after subtracting 0 from 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Advancing to step 13:
1200 divided by 639 is 1 with a remainder of 561.
Put 1 as the next digit of the answer. 
Result so far: 114612.89201
Subtracting 639 from 1200 leaves us with 561.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5610, and continue the process.

Step 14:
639 can be fit into 5610 8 times, resulting in a remainder of 498.
Use 8 as the next digit of our solution. 
Result so far: 114612.892018
If we subtract 5112 from 5610, we get 498.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4980, and continue the process.

Advancing to step 15:
4980 divided by 639 is 7 with a remainder of 507.
Use 7 as the next digit of our solution. 
Result so far: 114612.8920187
If we subtract 4473 from 4980, we get 507.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5070, and continue the process.

On to step 16:
5070 divided by 639 is 7 with a remainder of 597.
Record the quotient 7 as the next digit in the result. 
Result so far: 114612.89201877
The remainder is 597 after subtracting 4473 from 5070.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5970, and continue the process.

The final outcome is 114612.89201877, with a leftover of 5.97e-07.
