42385370 divided by 173 
The aim is to understand the frequency of 173 in 42385370.

Step 1:
173 goes into 4 0 times with a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Fetch the next digit (2) from the dividend, attach it to 4 and continue: 42 / 173

Let's proceed to step 2:
173 can be fit into 42 0 times, resulting in a remainder of 42.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 42 and we're left with 42.
Fetch the next digit (3) from the dividend, attach it to 42 and continue: 423 / 173

Moving on to step 3:
173 can be fit into 423 2 times, resulting in a remainder of 77.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
Subtracting 346 from 423 leaves us with 77.
Take the next digit (8) from the dividend and append it to 77, then repeat: 778 / 173

Let's proceed to step 4:
778 divided by 173 is 4 with a remainder of 86.
Record the quotient 4 as the next digit in the result. 
Result so far: 24.0
If we take 692 away from 778, we end up with 86.
Fetch the next digit (5) from the dividend, attach it to 86 and continue: 865 / 173

Let's proceed to step 5:
865 divided by 173 is 5 with a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 245.0
If we take 865 away from 865, we end up with 0.
Include the next digit (3) from the dividend after 0, then repeat: 3 / 173

On to step 6:
173 can be fit into 3 0 times, resulting in a remainder of 3.
The next digit of our result is 0. 
Result so far: 2450.0
If we take 0 away from 3, we end up with 3.
Bring next digit (7) of the dividend behind the 3 and repeat the process: 37 / 173

Step 7:
173 can be fit into 37 0 times, resulting in a remainder of 37.
The number 0 becomes the next digit in our result. 
Result so far: 24500.0
Subtract 0 from 37 to get 37.
Fetch the next digit (0) from the dividend, attach it to 37 and continue: 370 / 173

Advancing to step 8:
If we divide 370 by 173, we get 2 and a remainder of 24.
Write down 2 as next digit of the result. 
Result so far: 245002.0
If we subtract 346 from 370, we get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Step 9:
240 divided by 173 is 1 with a remainder of 67.
Record the quotient 1 as the next digit in the result. 
Result so far: 245002.1
If we take 173 away from 240, we end up with 67.
Since there are no more digits in the dividend, we add a zero to the remainder making it 670, and continue the process.

Going ahead to step 10:
670 divided by 173 is 3 with a remainder of 151.
Record the quotient 3 as the next digit in the result. 
Result so far: 245002.13
If we take 519 away from 670, we end up with 151.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1510, and continue the process.

Step 11:
173 can be fit into 1510 8 times, resulting in a remainder of 126.
Record the quotient 8 as the next digit in the result. 
Result so far: 245002.138
Subtracting 1384 from 1510 leaves us with 126.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1260, and continue the process.

On to step 12:
When dividing 1260 by 173, we get 7 with a remainder of 49.
Use 7 as the next digit of our solution. 
Result so far: 245002.1387
If we subtract 1211 from 1260, we get 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

On to step 13:
490 divided by 173 is 2 with a remainder of 144.
Record the quotient 2 as the next digit in the result. 
Result so far: 245002.13872
If we take 346 away from 490, we end up 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.

Going ahead to step 14:
1440 divided by 173 is 8 with a remainder of 56.
The next digit of our result is 8. 
Result so far: 245002.138728
If we take 1384 away from 1440, we end up with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Moving on to step 15:
The number 173 fits into 560 3 times, leaving a remainder of 41.
Record the quotient 3 as the next digit in the result. 
Result so far: 245002.1387283
If we subtract 519 from 560, we 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.

On to step 16:
When dividing 410 by 173, we get 2 with a remainder of 64.
The number 2 becomes the next digit in our result. 
Result so far: 245002.13872832
If we take 346 away from 410, we end up with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

The quotient of the division is 245002.13872832, and the remainder is 6.4e-08.
