We're dividing 30337986 by 418 
The aim is to understand the frequency of 418 in 30337986.

On to step 1:
The number 418 fits into 3 0 times, leaving a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Grab the next digit (0) from the dividend, add it to 3, then carry on: 30 / 418

Step 2:
If we divide 30 by 418, we get 0 and a remainder of 30.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 30 leaves us with 30.
Append the next digit (3) from the dividend to 30 and continue with: 303 / 418

Moving on to step 3:
If we divide 303 by 418, we get 0 and a remainder of 303.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 303, we end up with 303.
Append the next digit (3) from the dividend to 303 and continue with: 3033 / 418

Advancing to step 4:
418 can be fit into 3033 7 times, resulting in a remainder of 107.
Use 7 as the next digit of our solution. 
Result so far: 7.0
Subtract 2926 from 3033 to get 107.
Grab the next digit (7) from the dividend, add it to 107, then carry on: 1077 / 418

Going ahead to step 5:
1077 divided by 418 is 2 with a remainder of 241.
The next digit of our result is 2. 
Result so far: 72.0
If we take 836 away from 1077, we end up with 241.
Bring next digit (9) of the dividend behind the 241 and repeat the process: 2419 / 418

Going ahead to step 6:
418 can be fit into 2419 5 times, resulting in a remainder of 329.
Record the quotient 5 as the next digit in the result. 
Result so far: 725.0
Subtracting 2090 from 2419 leaves us with 329.
Take the next digit (8) from the dividend and append it to 329, then repeat: 3298 / 418

Advancing to step 7:
If we divide 3298 by 418, we get 7 and a remainder of 372.
Use 7 as the next digit of our solution. 
Result so far: 7257.0
If we subtract 2926 from 3298, we get 372.
Grab the next digit (6) from the dividend, add it to 372, then carry on: 3726 / 418

Let's proceed to step 8:
When dividing 3726 by 418, we get 8 with a remainder of 382.
Write down 8 as next digit of the result. 
Result so far: 72578.0
If we take 3344 away from 3726, we end up with 382.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3820, and continue the process.

On to step 9:
When dividing 3820 by 418, we get 9 with a remainder of 58.
Put 9 as the next digit of the answer. 
Result so far: 72578.9
Deduct 3762 from 3820 and we're left with 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

On to step 10:
418 can be fit into 580 1 times, resulting in a remainder of 162.
The next digit of our result is 1. 
Result so far: 72578.91
The remainder is 162 after subtracting 418 from 580.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1620, and continue the process.

On to step 11:
418 goes into 1620 3 times with a remainder of 366.
Use 3 as the next digit of our solution. 
Result so far: 72578.913
Deduct 1254 from 1620 and we're left with 366.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3660, and continue the process.

Let's proceed to step 12:
418 goes into 3660 8 times with a remainder of 316.
Put 8 as the next digit of the answer. 
Result so far: 72578.9138
Subtracting 3344 from 3660 leaves us with 316.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3160, and continue the process.

On to step 13:
418 goes into 3160 7 times with a remainder of 234.
Use 7 as the next digit of our solution. 
Result so far: 72578.91387
Subtracting 2926 from 3160 leaves us with 234.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2340, and continue the process.

On to step 14:
418 can be fit into 2340 5 times, resulting in a remainder of 250.
Put 5 as the next digit of the answer. 
Result so far: 72578.913875
Subtracting 2090 from 2340 leaves us with 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2500, and continue the process.

Advancing to step 15:
2500 divided by 418 is 5 with a remainder of 410.
Write down 5 as next digit of the result. 
Result so far: 72578.9138755
Deduct 2090 from 2500 and we're left with 410.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4100, and continue the process.

The final result is 72578.9138755 with a remainder of 4.1e-06.
