We divide 980921 by 78
The aim is to understand the frequency of 78 in 980921.

Going ahead to step 1:
78 can be fit into 9 0 times, resulting in a remainder of 9.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 9, we end up with 9.
Append the next digit (8) from the dividend to 9 and continue with: 98 / 78

Step 2:
98 divided by 78 is 1 with a remainder of 20.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we take 78 away from 98, we end up with 20.
Append the next digit (0) from the dividend to 20 and continue with: 200 / 78

Let's proceed to step 3:
78 goes into 200 2 times with a remainder of 44.
Record the quotient 2 as the next digit in the result. 
Result so far: 12.0
If we take 156 away from 200, we end up with 44.
Fetch the next digit (9) from the dividend, attach it to 44 and continue: 449 / 78

Step 4:
The number 78 fits into 449 5 times, leaving a remainder of 59.
Put 5 as the next digit of the answer. 
Result so far: 125.0
Deduct 390 from 449 and we're left with 59.
Append the next digit (2) from the dividend to 59 and continue with: 592 / 78

On to step 5:
If we divide 592 by 78, we get 7 and a remainder of 46.
Use 7 as the next digit of our solution. 
Result so far: 1257.0
Subtracting 546 from 592 leaves us with 46.
Grab the next digit (1) from the dividend, add it to 46, then carry on: 461 / 78

Let's proceed to step 6:
78 goes into 461 5 times with a remainder of 71.
Record the quotient 5 as the next digit in the result. 
Result so far: 12575.0
Subtracting 390 from 461 leaves us with 71.
Since there are no more digits in the dividend, we add a zero to the remainder making it 710, and continue the process.

Going ahead to step 7:
When dividing 710 by 78, we get 9 with a remainder of 8.
Use 9 as the next digit of our solution. 
Result so far: 12575.9
Subtracting 702 from 710 leaves us with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

On to step 8:
If we divide 80 by 78, we get 1 and a remainder of 2.
Record the quotient 1 as the next digit in the result. 
Result so far: 12575.91
Subtracting 78 from 80 leaves us with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Let's proceed to step 9:
When dividing 20 by 78, we get 0 with a remainder of 20.
The next digit of our result is 0. 
Result so far: 12575.91
If we take 0 away from 20, we end up with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Step 10:
78 goes into 200 2 times with a remainder of 44.
Record the quotient 2 as the next digit in the result. 
Result so far: 12575.9102
Subtract 156 from 200 to get 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Advancing to step 11:
78 can be fit into 440 5 times, resulting in a remainder of 50.
Put 5 as the next digit of the answer. 
Result so far: 12575.91025
The remainder is 50 after subtracting 390 from 440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Step 12:
When dividing 500 by 78, we get 6 with a remainder of 32.
Use 6 as the next digit of our solution. 
Result so far: 12575.910256
If we subtract 468 from 500, we get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

On to step 13:
If we divide 320 by 78, we get 4 and a remainder of 8.
Record the quotient 4 as the next digit in the result. 
Result so far: 12575.9102564
Subtracting 312 from 320 leaves us with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Going ahead to step 14:
If we divide 80 by 78, we get 1 and a remainder of 2.
The next digit of our result is 1. 
Result so far: 12575.91025641
The remainder is 2 after subtracting 78 from 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Our division results in 12575.91025641 with a remaining 2e-09.
