60186704 ÷ 873 
The aim is to understand the frequency of 873 in 60186704.

On to step 1:
6 divided by 873 is 0 with a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Include the next digit (0) from the dividend after 6, then repeat: 60 / 873

Let's proceed to step 2:
873 goes into 60 0 times with a remainder of 60.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 60 leaves us with 60.
Bring next digit (1) of the dividend behind the 60 and repeat the process: 601 / 873

Advancing to step 3:
If we divide 601 by 873, we get 0 and a remainder of 601.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 601 and we're left with 601.
Append the next digit (8) from the dividend to 601 and continue with: 6018 / 873

Step 4:
873 can be fit into 6018 6 times, resulting in a remainder of 780.
The next digit of our result is 6. 
Result so far: 6.0
Subtract 5238 from 6018 to get 780.
Append the next digit (6) from the dividend to 780 and continue with: 7806 / 873

Advancing to step 5:
When dividing 7806 by 873, we get 8 with a remainder of 822.
Write down 8 as next digit of the result. 
Result so far: 68.0
Subtracting 6984 from 7806 leaves us with 822.
Include the next digit (7) from the dividend after 822, then repeat: 8227 / 873

Advancing to step 6:
8227 divided by 873 is 9 with a remainder of 370.
The number 9 becomes the next digit in our result. 
Result so far: 689.0
Subtract 7857 from 8227 to get 370.
Grab the next digit (0) from the dividend, add it to 370, then carry on: 3700 / 873

Advancing to step 7:
The number 873 fits into 3700 4 times, leaving a remainder of 208.
Write down 4 as next digit of the result. 
Result so far: 6894.0
Subtract 3492 from 3700 to get 208.
Append the next digit (4) from the dividend to 208 and continue with: 2084 / 873

Let's proceed to step 8:
2084 divided by 873 is 2 with a remainder of 338.
Record the quotient 2 as the next digit in the result. 
Result so far: 68942.0
If we take 1746 away from 2084, we end up with 338.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3380, and continue the process.

On to step 9:
The number 873 fits into 3380 3 times, leaving a remainder of 761.
Write down 3 as next digit of the result. 
Result so far: 68942.3
Subtract 2619 from 3380 to get 761.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7610, and continue the process.

Moving on to step 10:
When dividing 7610 by 873, we get 8 with a remainder of 626.
The next digit of our result is 8. 
Result so far: 68942.38
Deduct 6984 from 7610 and we're left with 626.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6260, and continue the process.

On to step 11:
If we divide 6260 by 873, we get 7 and a remainder of 149.
Record the quotient 7 as the next digit in the result. 
Result so far: 68942.387
If we subtract 6111 from 6260, we get 149.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1490, and continue the process.

Let's proceed to step 12:
873 goes into 1490 1 times with a remainder of 617.
Record the quotient 1 as the next digit in the result. 
Result so far: 68942.3871
If we subtract 873 from 1490, we get 617.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6170, and continue the process.

Step 13:
873 goes into 6170 7 times with a remainder of 59.
Use 7 as the next digit of our solution. 
Result so far: 68942.38717
Deduct 6111 from 6170 and we're left with 59.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

Advancing to step 14:
873 can be fit into 590 0 times, resulting in a remainder of 590.
Record the quotient 0 as the next digit in the result. 
Result so far: 68942.38717
If we take 0 away from 590, we end up with 590.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5900, and continue the process.

Step 15:
873 can be fit into 5900 6 times, resulting in a remainder of 662.
The next digit of our result is 6. 
Result so far: 68942.3871706
Subtract 5238 from 5900 to get 662.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6620, and continue the process.

On to step 16:
873 goes into 6620 7 times with a remainder of 509.
The next digit of our result is 7. 
Result so far: 68942.38717067
If we subtract 6111 from 6620, we get 509.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5090, and continue the process.

The final outcome is 68942.38717067, with a leftover of 5.09e-07.
