78722565 ÷ 407 
The aim is to understand the frequency of 407 in 78722565.

Advancing to step 1:
407 goes into 7 0 times with a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Fetch the next digit (8) from the dividend, attach it to 7 and continue: 78 / 407

Let's proceed to step 2:
407 can be fit into 78 0 times, resulting in a remainder of 78.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 78 and we're left with 78.
Include the next digit (7) from the dividend after 78, then repeat: 787 / 407

Step 3:
787 divided by 407 is 1 with a remainder of 380.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtract 407 from 787 to get 380.
Bring next digit (2) of the dividend behind the 380 and repeat the process: 3802 / 407

On to step 4:
407 goes into 3802 9 times with a remainder of 139.
The number 9 becomes the next digit in our result. 
Result so far: 19.0
Subtract 3663 from 3802 to get 139.
Grab the next digit (2) from the dividend, add it to 139, then carry on: 1392 / 407

Let's proceed to step 5:
407 goes into 1392 3 times with a remainder of 171.
Record the quotient 3 as the next digit in the result. 
Result so far: 193.0
Subtract 1221 from 1392 to get 171.
Fetch the next digit (5) from the dividend, attach it to 171 and continue: 1715 / 407

Advancing to step 6:
The number 407 fits into 1715 4 times, leaving a remainder of 87.
Use 4 as the next digit of our solution. 
Result so far: 1934.0
If we subtract 1628 from 1715, we get 87.
Grab the next digit (6) from the dividend, add it to 87, then carry on: 876 / 407

Step 7:
876 divided by 407 is 2 with a remainder of 62.
Put 2 as the next digit of the answer. 
Result so far: 19342.0
Subtract 814 from 876 to get 62.
Bring next digit (5) of the dividend behind the 62 and repeat the process: 625 / 407

Let's proceed to step 8:
625 divided by 407 is 1 with a remainder of 218.
The number 1 becomes the next digit in our result. 
Result so far: 193421.0
Subtract 407 from 625 to get 218.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2180, and continue the process.

Advancing to step 9:
407 goes into 2180 5 times with a remainder of 145.
Record the quotient 5 as the next digit in the result. 
Result so far: 193421.5
Deduct 2035 from 2180 and we're left with 145.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1450, and continue the process.

Advancing to step 10:
If we divide 1450 by 407, we get 3 and a remainder of 229.
Use 3 as the next digit of our solution. 
Result so far: 193421.53
If we take 1221 away from 1450, we end up with 229.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2290, and continue the process.

Step 11:
407 goes into 2290 5 times with a remainder of 255.
Record the quotient 5 as the next digit in the result. 
Result so far: 193421.535
If we take 2035 away from 2290, we end up with 255.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2550, and continue the process.

Let's proceed to step 12:
2550 divided by 407 is 6 with a remainder of 108.
The number 6 becomes the next digit in our result. 
Result so far: 193421.5356
Subtracting 2442 from 2550 leaves us with 108.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1080, and continue the process.

On to step 13:
If we divide 1080 by 407, we get 2 and a remainder of 266.
Record the quotient 2 as the next digit in the result. 
Result so far: 193421.53562
Deduct 814 from 1080 and we're left with 266.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2660, and continue the process.

Let's proceed to step 14:
When dividing 2660 by 407, we get 6 with a remainder of 218.
Use 6 as the next digit of our solution. 
Result so far: 193421.535626
Subtract 2442 from 2660 to get 218.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2180, and continue the process.

Advancing to step 15:
407 goes into 2180 5 times with a remainder of 145.
Use 5 as the next digit of our solution. 
Result so far: 193421.5356265
Subtracting 2035 from 2180 leaves us with 145.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1450, and continue the process.

Step 16:
1450 divided by 407 is 3 with a remainder of 229.
Put 3 as the next digit of the answer. 
Result so far: 193421.53562653
The remainder is 229 after subtracting 1221 from 1450.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2290, and continue the process.

Our division results in 193421.53562653 with a remaining 2.29e-07.
