72639038 divided by 173 
The aim is to understand the frequency of 173 in 72639038.

Advancing to step 1:
The number 173 fits into 7 0 times, leaving a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Take the next digit (2) from the dividend and append it to 7, then repeat: 72 / 173

On to step 2:
173 goes into 72 0 times with a remainder of 72.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 72 to get 72.
Fetch the next digit (6) from the dividend, attach it to 72 and continue: 726 / 173

Let's proceed to step 3:
726 divided by 173 is 4 with a remainder of 34.
Use 4 as the next digit of our solution. 
Result so far: 4.0
If we subtract 692 from 726, we get 34.
Bring next digit (3) of the dividend behind the 34 and repeat the process: 343 / 173

Moving on to step 4:
If we divide 343 by 173, we get 1 and a remainder of 170.
The next digit of our result is 1. 
Result so far: 41.0
If we take 173 away from 343, we end up with 170.
Grab the next digit (9) from the dividend, add it to 170, then carry on: 1709 / 173

Let's proceed to step 5:
The number 173 fits into 1709 9 times, leaving a remainder of 152.
Record the quotient 9 as the next digit in the result. 
Result so far: 419.0
Subtracting 1557 from 1709 leaves us with 152.
Fetch the next digit (0) from the dividend, attach it to 152 and continue: 1520 / 173

Moving on to step 6:
1520 divided by 173 is 8 with a remainder of 136.
Write down 8 as next digit of the result. 
Result so far: 4198.0
Subtract 1384 from 1520 to get 136.
Grab the next digit (3) from the dividend, add it to 136, then carry on: 1363 / 173

Moving on to step 7:
If we divide 1363 by 173, we get 7 and a remainder of 152.
The next digit of our result is 7. 
Result so far: 41987.0
Subtract 1211 from 1363 to get 152.
Append the next digit (8) from the dividend to 152 and continue with: 1528 / 173

Moving on to step 8:
When dividing 1528 by 173, we get 8 with a remainder of 144.
Write down 8 as next digit of the result. 
Result so far: 419878.0
Deduct 1384 from 1528 and we're left with 144.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1440, and continue the process.

Moving on to step 9:
When dividing 1440 by 173, we get 8 with a remainder of 56.
The number 8 becomes the next digit in our result. 
Result so far: 419878.8
If we subtract 1384 from 1440, we get 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Step 10:
173 can be fit into 560 3 times, resulting in a remainder of 41.
Use 3 as the next digit of our solution. 
Result so far: 419878.83
Subtract 519 from 560 to get 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Step 11:
If we divide 410 by 173, we get 2 and a remainder of 64.
Use 2 as the next digit of our solution. 
Result so far: 419878.832
If we subtract 346 from 410, we get 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Going ahead to step 12:
When dividing 640 by 173, we get 3 with a remainder of 121.
Put 3 as the next digit of the answer. 
Result so far: 419878.8323
Deduct 519 from 640 and we're left with 121.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1210, and continue the process.

Let's proceed to step 13:
If we divide 1210 by 173, we get 6 and a remainder of 172.
Use 6 as the next digit of our solution. 
Result so far: 419878.83236
Subtracting 1038 from 1210 leaves us with 172.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1720, and continue the process.

Moving on to step 14:
If we divide 1720 by 173, we get 9 and a remainder of 163.
The next digit of our result is 9. 
Result so far: 419878.832369
The remainder is 163 after subtracting 1557 from 1720.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1630, and continue the process.

Moving on to step 15:
If we divide 1630 by 173, we get 9 and a remainder of 73.
The number 9 becomes the next digit in our result. 
Result so far: 419878.8323699
Subtracting 1557 from 1630 leaves us with 73.
Since there are no more digits in the dividend, we add a zero to the remainder making it 730, and continue the process.

Our division results in 419878.8323699 with a remaining 7.3e-07.
