Let's divide 78890538 by 145
The aim is to understand the frequency of 145 in 78890538.

Let's proceed to step 1:
When dividing 7 by 145, we get 0 with a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Grab the next digit (8) from the dividend, add it to 7, then carry on: 78 / 145

Step 2:
145 can be fit into 78 0 times, resulting in a remainder of 78.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 78 after subtracting 0 from 78.
Take the next digit (8) from the dividend and append it to 78, then repeat: 788 / 145

On to step 3:
When dividing 788 by 145, we get 5 with a remainder of 63.
The next digit of our result is 5. 
Result so far: 5.0
Subtract 725 from 788 to get 63.
Bring next digit (9) of the dividend behind the 63 and repeat the process: 639 / 145

Advancing to step 4:
145 can be fit into 639 4 times, resulting in a remainder of 59.
Record the quotient 4 as the next digit in the result. 
Result so far: 54.0
Subtract 580 from 639 to get 59.
Bring next digit (0) of the dividend behind the 59 and repeat the process: 590 / 145

Going ahead to step 5:
590 divided by 145 is 4 with a remainder of 10.
The next digit of our result is 4. 
Result so far: 544.0
Subtracting 580 from 590 leaves us with 10.
Fetch the next digit (5) from the dividend, attach it to 10 and continue: 105 / 145

Going ahead to step 6:
If we divide 105 by 145, we get 0 and a remainder of 105.
Record the quotient 0 as the next digit in the result. 
Result so far: 5440.0
If we subtract 0 from 105, we get 105.
Take the next digit (3) from the dividend and append it to 105, then repeat: 1053 / 145

Step 7:
145 goes into 1053 7 times with a remainder of 38.
The number 7 becomes the next digit in our result. 
Result so far: 54407.0
Deduct 1015 from 1053 and we're left with 38.
Grab the next digit (8) from the dividend, add it to 38, then carry on: 388 / 145

Moving on to step 8:
The number 145 fits into 388 2 times, leaving a remainder of 98.
The next digit of our result is 2. 
Result so far: 544072.0
Subtract 290 from 388 to get 98.
Since there are no more digits in the dividend, we add a zero to the remainder making it 980, and continue the process.

Step 9:
When dividing 980 by 145, we get 6 with a remainder of 110.
Put 6 as the next digit of the answer. 
Result so far: 544072.6
Subtracting 870 from 980 leaves us with 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1100, and continue the process.

On to step 10:
1100 divided by 145 is 7 with a remainder of 85.
Record the quotient 7 as the next digit in the result. 
Result so far: 544072.67
Subtracting 1015 from 1100 leaves us with 85.
Since there are no more digits in the dividend, we add a zero to the remainder making it 850, and continue the process.

Going ahead to step 11:
145 goes into 850 5 times with a remainder of 125.
The next digit of our result is 5. 
Result so far: 544072.675
If we subtract 725 from 850, we get 125.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1250, and continue the process.

On to step 12:
145 can be fit into 1250 8 times, resulting in a remainder of 90.
Write down 8 as next digit of the result. 
Result so far: 544072.6758
Subtracting 1160 from 1250 leaves us with 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

Going ahead to step 13:
If we divide 900 by 145, we get 6 and a remainder of 30.
The next digit of our result is 6. 
Result so far: 544072.67586
Subtracting 870 from 900 leaves us with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

On to step 14:
300 divided by 145 is 2 with a remainder of 10.
The next digit of our result is 2. 
Result so far: 544072.675862
The remainder is 10 after subtracting 290 from 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 15:
If we divide 100 by 145, we get 0 and a remainder of 100.
The number 0 becomes the next digit in our result. 
Result so far: 544072.675862
If we take 0 away from 100, we end up with 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Step 16:
The number 145 fits into 1000 6 times, leaving a remainder of 130.
Write down 6 as next digit of the result. 
Result so far: 544072.67586206
Subtracting 870 from 1000 leaves us with 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

Our division results in 544072.67586206 with a remaining 1.3e-07.
