Let's divide 61939 by 79
The aim is to understand the frequency of 79 in 61939.

On to step 1:
If we divide 6 by 79, we get 0 and a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Append the next digit (1) from the dividend to 6 and continue with: 61 / 79

Advancing to step 2:
79 goes into 61 0 times with a remainder of 61.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 61 leaves us with 61.
Grab the next digit (9) from the dividend, add it to 61, then carry on: 619 / 79

Moving on to step 3:
When dividing 619 by 79, we get 7 with a remainder of 66.
The number 7 becomes the next digit in our result. 
Result so far: 7.0
Deduct 553 from 619 and we're left with 66.
Append the next digit (3) from the dividend to 66 and continue with: 663 / 79

Let's proceed to step 4:
If we divide 663 by 79, we get 8 and a remainder of 31.
Record the quotient 8 as the next digit in the result. 
Result so far: 78.0
If we subtract 632 from 663, we get 31.
Append the next digit (9) from the dividend to 31 and continue with: 319 / 79

On to step 5:
When dividing 319 by 79, we get 4 with a remainder of 3.
Use 4 as the next digit of our solution. 
Result so far: 784.0
Deduct 316 from 319 and we're left with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Let's proceed to step 6:
79 can be fit into 30 0 times, resulting in a remainder of 30.
The number 0 becomes the next digit in our result. 
Result so far: 784.0
Subtract 0 from 30 to get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Let's proceed to step 7:
The number 79 fits into 300 3 times, leaving a remainder of 63.
Use 3 as the next digit of our solution. 
Result so far: 784.03
Deduct 237 from 300 and we're left with 63.
Since there are no more digits in the dividend, we add a zero to the remainder making it 630, and continue the process.

Let's proceed to step 8:
If we divide 630 by 79, we get 7 and a remainder of 77.
The next digit of our result is 7. 
Result so far: 784.037
If we take 553 away from 630, we end up with 77.
Since there are no more digits in the dividend, we add a zero to the remainder making it 770, and continue the process.

On to step 9:
770 divided by 79 is 9 with a remainder of 59.
The number 9 becomes the next digit in our result. 
Result so far: 784.0379
If we subtract 711 from 770, we get 59.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

On to step 10:
79 goes into 590 7 times with a remainder of 37.
Use 7 as the next digit of our solution. 
Result so far: 784.03797
The remainder is 37 after subtracting 553 from 590.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Moving on to step 11:
79 can be fit into 370 4 times, resulting in a remainder of 54.
Put 4 as the next digit of the answer. 
Result so far: 784.037974
The remainder is 54 after subtracting 316 from 370.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Moving on to step 12:
79 goes into 540 6 times with a remainder of 66.
Use 6 as the next digit of our solution. 
Result so far: 784.0379746
Subtracting 474 from 540 leaves us with 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Moving on to step 13:
79 goes into 660 8 times with a remainder of 28.
Record the quotient 8 as the next digit in the result. 
Result so far: 784.03797468
Subtract 632 from 660 to get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

In conclusion, the division gives 784.03797468 with a balance of 2.8e-08.
