We divide 15860413 by 425
The aim is to understand the frequency of 425 in 15860413.

On to step 1:
1 divided by 425 is 0 with a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Bring next digit (5) of the dividend behind the 1 and repeat the process: 15 / 425

On to step 2:
When dividing 15 by 425, we get 0 with a remainder of 15.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 15 to get 15.
Append the next digit (8) from the dividend to 15 and continue with: 158 / 425

Moving on to step 3:
If we divide 158 by 425, we get 0 and a remainder of 158.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 158 after subtracting 0 from 158.
Include the next digit (6) from the dividend after 158, then repeat: 1586 / 425

Moving on to step 4:
425 goes into 1586 3 times with a remainder of 311.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
If we subtract 1275 from 1586, we get 311.
Append the next digit (0) from the dividend to 311 and continue with: 3110 / 425

Step 5:
When dividing 3110 by 425, we get 7 with a remainder of 135.
Record the quotient 7 as the next digit in the result. 
Result so far: 37.0
If we subtract 2975 from 3110, we get 135.
Take the next digit (4) from the dividend and append it to 135, then repeat: 1354 / 425

Going ahead to step 6:
1354 divided by 425 is 3 with a remainder of 79.
Write down 3 as next digit of the result. 
Result so far: 373.0
If we take 1275 away from 1354, we end up with 79.
Fetch the next digit (1) from the dividend, attach it to 79 and continue: 791 / 425

Going ahead to step 7:
The number 425 fits into 791 1 times, leaving a remainder of 366.
The next digit of our result is 1. 
Result so far: 3731.0
If we take 425 away from 791, we end up with 366.
Take the next digit (3) from the dividend and append it to 366, then repeat: 3663 / 425

Advancing to step 8:
When dividing 3663 by 425, we get 8 with a remainder of 263.
Put 8 as the next digit of the answer. 
Result so far: 37318.0
If we subtract 3400 from 3663, we get 263.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2630, and continue the process.

On to step 9:
425 goes into 2630 6 times with a remainder of 80.
Put 6 as the next digit of the answer. 
Result so far: 37318.6
Subtracting 2550 from 2630 leaves us with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

On to step 10:
When dividing 800 by 425, we get 1 with a remainder of 375.
Put 1 as the next digit of the answer. 
Result so far: 37318.61
Deduct 425 from 800 and we're left with 375.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3750, and continue the process.

Moving on to step 11:
3750 divided by 425 is 8 with a remainder of 350.
The number 8 becomes the next digit in our result. 
Result so far: 37318.618
Subtracting 3400 from 3750 leaves us with 350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3500, and continue the process.

On to step 12:
425 goes into 3500 8 times with a remainder of 100.
Record the quotient 8 as the next digit in the result. 
Result so far: 37318.6188
Subtract 3400 from 3500 to get 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

In conclusion, the division gives 37318.6188 with a balance of 0.001.
