We divide 78424375 by 245
The aim is to understand the frequency of 245 in 78424375.

Moving on to step 1:
245 can be fit into 7 0 times, resulting in a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Take the next digit (8) from the dividend and append it to 7, then repeat: 78 / 245

Going ahead to step 2:
78 divided by 245 is 0 with a remainder of 78.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 78, we end up with 78.
Include the next digit (4) from the dividend after 78, then repeat: 784 / 245

Going ahead to step 3:
When dividing 784 by 245, we get 3 with a remainder of 49.
Write down 3 as next digit of the result. 
Result so far: 3.0
Subtracting 735 from 784 leaves us with 49.
Bring next digit (2) of the dividend behind the 49 and repeat the process: 492 / 245

Going ahead to step 4:
The number 245 fits into 492 2 times, leaving a remainder of 2.
Put 2 as the next digit of the answer. 
Result so far: 32.0
Deduct 490 from 492 and we're left with 2.
Fetch the next digit (4) from the dividend, attach it to 2 and continue: 24 / 245

Going ahead to step 5:
When dividing 24 by 245, we get 0 with a remainder of 24.
The next digit of our result is 0. 
Result so far: 320.0
Deduct 0 from 24 and we're left with 24.
Grab the next digit (3) from the dividend, add it to 24, then carry on: 243 / 245

Step 6:
If we divide 243 by 245, we get 0 and a remainder of 243.
Put 0 as the next digit of the answer. 
Result so far: 3200.0
If we subtract 0 from 243, we get 243.
Take the next digit (7) from the dividend and append it to 243, then repeat: 2437 / 245

Step 7:
When dividing 2437 by 245, we get 9 with a remainder of 232.
Record the quotient 9 as the next digit in the result. 
Result so far: 32009.0
The remainder is 232 after subtracting 2205 from 2437.
Include the next digit (5) from the dividend after 232, then repeat: 2325 / 245

Moving on to step 8:
245 can be fit into 2325 9 times, resulting in a remainder of 120.
Put 9 as the next digit of the answer. 
Result so far: 320099.0
The remainder is 120 after subtracting 2205 from 2325.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Advancing to step 9:
245 goes into 1200 4 times with a remainder of 220.
Write down 4 as next digit of the result. 
Result so far: 320099.4
If we take 980 away from 1200, we end up with 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2200, and continue the process.

On to step 10:
If we divide 2200 by 245, we get 8 and a remainder of 240.
Use 8 as the next digit of our solution. 
Result so far: 320099.48
Subtract 1960 from 2200 to get 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

On to step 11:
When dividing 2400 by 245, we get 9 with a remainder of 195.
Use 9 as the next digit of our solution. 
Result so far: 320099.489
Subtracting 2205 from 2400 leaves us with 195.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1950, and continue the process.

On to step 12:
245 goes into 1950 7 times with a remainder of 235.
Put 7 as the next digit of the answer. 
Result so far: 320099.4897
The remainder is 235 after subtracting 1715 from 1950.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2350, and continue the process.

Step 13:
When dividing 2350 by 245, we get 9 with a remainder of 145.
Put 9 as the next digit of the answer. 
Result so far: 320099.48979
The remainder is 145 after subtracting 2205 from 2350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1450, and continue the process.

Going ahead to step 14:
If we divide 1450 by 245, we get 5 and a remainder of 225.
The number 5 becomes the next digit in our result. 
Result so far: 320099.489795
If we take 1225 away from 1450, we end up with 225.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2250, and continue the process.

Going ahead to step 15:
245 goes into 2250 9 times with a remainder of 45.
Record the quotient 9 as the next digit in the result. 
Result so far: 320099.4897959
Subtract 2205 from 2250 to get 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Moving on to step 16:
245 goes into 450 1 times with a remainder of 205.
Use 1 as the next digit of our solution. 
Result so far: 320099.48979591
Deduct 245 from 450 and we're left with 205.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2050, and continue the process.

The final result is 320099.48979591 with a remainder of 2.05e-07.
