8127502 divided by 407 
The aim is to understand the frequency of 407 in 8127502.

Advancing to step 1:
407 goes into 8 0 times with a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Include the next digit (1) from the dividend after 8, then repeat: 81 / 407

Moving on to step 2:
407 goes into 81 0 times with a remainder of 81.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 81 and we're left with 81.
Append the next digit (2) from the dividend to 81 and continue with: 812 / 407

Advancing to step 3:
407 can be fit into 812 1 times, resulting in a remainder of 405.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtract 407 from 812 to get 405.
Grab the next digit (7) from the dividend, add it to 405, then carry on: 4057 / 407

Going ahead to step 4:
The number 407 fits into 4057 9 times, leaving a remainder of 394.
Use 9 as the next digit of our solution. 
Result so far: 19.0
If we take 3663 away from 4057, we end up with 394.
Fetch the next digit (5) from the dividend, attach it to 394 and continue: 3945 / 407

Let's proceed to step 5:
3945 divided by 407 is 9 with a remainder of 282.
Record the quotient 9 as the next digit in the result. 
Result so far: 199.0
Deduct 3663 from 3945 and we're left with 282.
Grab the next digit (0) from the dividend, add it to 282, then carry on: 2820 / 407

Step 6:
2820 divided by 407 is 6 with a remainder of 378.
Record the quotient 6 as the next digit in the result. 
Result so far: 1996.0
Subtract 2442 from 2820 to get 378.
Take the next digit (2) from the dividend and append it to 378, then repeat: 3782 / 407

Going ahead to step 7:
407 goes into 3782 9 times with a remainder of 119.
Put 9 as the next digit of the answer. 
Result so far: 19969.0
The remainder is 119 after subtracting 3663 from 3782.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1190, and continue the process.

On to step 8:
When dividing 1190 by 407, we get 2 with a remainder of 376.
Record the quotient 2 as the next digit in the result. 
Result so far: 19969.2
If we take 814 away from 1190, we end up with 376.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3760, and continue the process.

Moving on to step 9:
3760 divided by 407 is 9 with a remainder of 97.
The next digit of our result is 9. 
Result so far: 19969.29
If we take 3663 away from 3760, we end up with 97.
Since there are no more digits in the dividend, we add a zero to the remainder making it 970, and continue the process.

Advancing to step 10:
970 divided by 407 is 2 with a remainder of 156.
Write down 2 as next digit of the result. 
Result so far: 19969.292
If we subtract 814 from 970, we get 156.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1560, and continue the process.

Step 11:
407 can be fit into 1560 3 times, resulting in a remainder of 339.
Put 3 as the next digit of the answer. 
Result so far: 19969.2923
If we subtract 1221 from 1560, we get 339.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3390, and continue the process.

Moving on to step 12:
407 can be fit into 3390 8 times, resulting in a remainder of 134.
Record the quotient 8 as the next digit in the result. 
Result so far: 19969.29238
Deduct 3256 from 3390 and we're left with 134.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1340, and continue the process.

Moving on to step 13:
When dividing 1340 by 407, we get 3 with a remainder of 119.
The number 3 becomes the next digit in our result. 
Result so far: 19969.292383
If we take 1221 away from 1340, we end up with 119.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1190, and continue the process.

On to step 14:
407 can be fit into 1190 2 times, resulting in a remainder of 376.
Put 2 as the next digit of the answer. 
Result so far: 19969.2923832
The remainder is 376 after subtracting 814 from 1190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3760, and continue the process.

Let's proceed to step 15:
If we divide 3760 by 407, we get 9 and a remainder of 97.
Put 9 as the next digit of the answer. 
Result so far: 19969.29238329
If we take 3663 away from 3760, we end up with 97.
Since there are no more digits in the dividend, we add a zero to the remainder making it 970, and continue the process.

Our division results in 19969.29238329 with a remaining 9.7e-08.
