66294563 ÷ 790 
The aim is to understand the frequency of 790 in 66294563.

Step 1:
6 divided by 790 is 0 with a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Grab the next digit (6) from the dividend, add it to 6, then carry on: 66 / 790

Moving on to step 2:
790 goes into 66 0 times with a remainder of 66.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 66 to get 66.
Bring next digit (2) of the dividend behind the 66 and repeat the process: 662 / 790

Advancing to step 3:
790 goes into 662 0 times with a remainder of 662.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 662 leaves us with 662.
Fetch the next digit (9) from the dividend, attach it to 662 and continue: 6629 / 790

Advancing to step 4:
When dividing 6629 by 790, we get 8 with a remainder of 309.
Use 8 as the next digit of our solution. 
Result so far: 8.0
Subtracting 6320 from 6629 leaves us with 309.
Append the next digit (4) from the dividend to 309 and continue with: 3094 / 790

Moving on to step 5:
790 goes into 3094 3 times with a remainder of 724.
Put 3 as the next digit of the answer. 
Result so far: 83.0
If we subtract 2370 from 3094, we get 724.
Bring next digit (5) of the dividend behind the 724 and repeat the process: 7245 / 790

Going ahead to step 6:
When dividing 7245 by 790, we get 9 with a remainder of 135.
Record the quotient 9 as the next digit in the result. 
Result so far: 839.0
Subtracting 7110 from 7245 leaves us with 135.
Include the next digit (6) from the dividend after 135, then repeat: 1356 / 790

Moving on to step 7:
The number 790 fits into 1356 1 times, leaving a remainder of 566.
Use 1 as the next digit of our solution. 
Result so far: 8391.0
Deduct 790 from 1356 and we're left with 566.
Grab the next digit (3) from the dividend, add it to 566, then carry on: 5663 / 790

Moving on to step 8:
790 can be fit into 5663 7 times, resulting in a remainder of 133.
Record the quotient 7 as the next digit in the result. 
Result so far: 83917.0
If we subtract 5530 from 5663, we get 133.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1330, and continue the process.

Advancing to step 9:
If we divide 1330 by 790, we get 1 and a remainder of 540.
Write down 1 as next digit of the result. 
Result so far: 83917.1
If we subtract 790 from 1330, we get 540.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5400, and continue the process.

On to step 10:
When dividing 5400 by 790, we get 6 with a remainder of 660.
Put 6 as the next digit of the answer. 
Result so far: 83917.16
If we subtract 4740 from 5400, we get 660.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6600, and continue the process.

Let's proceed to step 11:
6600 divided by 790 is 8 with a remainder of 280.
Put 8 as the next digit of the answer. 
Result so far: 83917.168
If we take 6320 away from 6600, we end up with 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

On to step 12:
If we divide 2800 by 790, we get 3 and a remainder of 430.
The next digit of our result is 3. 
Result so far: 83917.1683
Subtracting 2370 from 2800 leaves us with 430.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4300, and continue the process.

Moving on to step 13:
790 can be fit into 4300 5 times, resulting in a remainder of 350.
Put 5 as the next digit of the answer. 
Result so far: 83917.16835
If we take 3950 away from 4300, we end up with 350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3500, and continue the process.

Going ahead to step 14:
The number 790 fits into 3500 4 times, leaving a remainder of 340.
The next digit of our result is 4. 
Result so far: 83917.168354
The remainder is 340 after subtracting 3160 from 3500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3400, and continue the process.

Let's proceed to step 15:
The number 790 fits into 3400 4 times, leaving a remainder of 240.
Use 4 as the next digit of our solution. 
Result so far: 83917.1683544
Subtracting 3160 from 3400 leaves us with 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

In conclusion, the division gives 83917.1683544 with a balance of 2.4e-06.
