73644860 divided by 487 
The aim is to understand the frequency of 487 in 73644860.

Step 1:
The number 487 fits into 7 0 times, leaving a remainder of 7.
Write down 0 as next digit of 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 / 487

Step 2:
If we divide 73 by 487, we get 0 and a remainder of 73.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 73 and we're left with 73.
Append the next digit (6) from the dividend to 73 and continue with: 736 / 487

Moving on to step 3:
736 divided by 487 is 1 with a remainder of 249.
The next digit of our result is 1. 
Result so far: 1.0
Subtract 487 from 736 to get 249.
Grab the next digit (4) from the dividend, add it to 249, then carry on: 2494 / 487

Going ahead to step 4:
The number 487 fits into 2494 5 times, leaving a remainder of 59.
Use 5 as the next digit of our solution. 
Result so far: 15.0
Deduct 2435 from 2494 and we're left with 59.
Fetch the next digit (4) from the dividend, attach it to 59 and continue: 594 / 487

On to step 5:
487 goes into 594 1 times with a remainder of 107.
Write down 1 as next digit of the result. 
Result so far: 151.0
Subtract 487 from 594 to get 107.
Bring next digit (8) of the dividend behind the 107 and repeat the process: 1078 / 487

Advancing to step 6:
487 goes into 1078 2 times with a remainder of 104.
The next digit of our result is 2. 
Result so far: 1512.0
Subtracting 974 from 1078 leaves us with 104.
Include the next digit (6) from the dividend after 104, then repeat: 1046 / 487

On to step 7:
1046 divided by 487 is 2 with a remainder of 72.
Use 2 as the next digit of our solution. 
Result so far: 15122.0
If we take 974 away from 1046, we end up with 72.
Grab the next digit (0) from the dividend, add it to 72, then carry on: 720 / 487

On to step 8:
720 divided by 487 is 1 with a remainder of 233.
Record the quotient 1 as the next digit in the result. 
Result so far: 151221.0
Deduct 487 from 720 and we're left with 233.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2330, and continue the process.

Let's proceed to step 9:
487 goes into 2330 4 times with a remainder of 382.
Record the quotient 4 as the next digit in the result. 
Result so far: 151221.4
If we subtract 1948 from 2330, we get 382.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3820, and continue the process.

Going ahead to step 10:
487 can be fit into 3820 7 times, resulting in a remainder of 411.
Use 7 as the next digit of our solution. 
Result so far: 151221.47
The remainder is 411 after subtracting 3409 from 3820.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4110, and continue the process.

Going ahead to step 11:
If we divide 4110 by 487, we get 8 and a remainder of 214.
Use 8 as the next digit of our solution. 
Result so far: 151221.478
The remainder is 214 after subtracting 3896 from 4110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2140, and continue the process.

Going ahead to step 12:
487 can be fit into 2140 4 times, resulting in a remainder of 192.
The next digit of our result is 4. 
Result so far: 151221.4784
If we take 1948 away from 2140, we end up with 192.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1920, and continue the process.

Step 13:
When dividing 1920 by 487, we get 3 with a remainder of 459.
Use 3 as the next digit of our solution. 
Result so far: 151221.47843
Subtracting 1461 from 1920 leaves us with 459.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4590, and continue the process.

Advancing to step 14:
When dividing 4590 by 487, we get 9 with a remainder of 207.
The number 9 becomes the next digit in our result. 
Result so far: 151221.478439
Subtracting 4383 from 4590 leaves us with 207.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2070, and continue the process.

Advancing to step 15:
When dividing 2070 by 487, we get 4 with a remainder of 122.
Record the quotient 4 as the next digit in the result. 
Result so far: 151221.4784394
If we subtract 1948 from 2070, we get 122.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1220, and continue the process.

Moving on to step 16:
487 can be fit into 1220 2 times, resulting in a remainder of 246.
Record the quotient 2 as the next digit in the result. 
Result so far: 151221.47843942
If we take 974 away from 1220, we end up with 246.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2460, and continue the process.

The final result is 151221.47843942 with a remainder of 2.46e-07.
