We look at the division of 81610222 by 790 
The aim is to understand the frequency of 790 in 81610222.

Going ahead to step 1:
The number 790 fits into 8 0 times, leaving a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Take the next digit (1) from the dividend and append it to 8, then repeat: 81 / 790

Let's proceed to step 2:
The number 790 fits into 81 0 times, leaving a remainder of 81.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 81 after subtracting 0 from 81.
Grab the next digit (6) from the dividend, add it to 81, then carry on: 816 / 790

On to step 3:
When dividing 816 by 790, we get 1 with a remainder of 26.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtract 790 from 816 to get 26.
Bring next digit (1) of the dividend behind the 26 and repeat the process: 261 / 790

Let's proceed to step 4:
261 divided by 790 is 0 with a remainder of 261.
Write down 0 as next digit of the result. 
Result so far: 10.0
If we take 0 away from 261, we end up with 261.
Fetch the next digit (0) from the dividend, attach it to 261 and continue: 2610 / 790

Let's proceed to step 5:
When dividing 2610 by 790, we get 3 with a remainder of 240.
Use 3 as the next digit of our solution. 
Result so far: 103.0
If we take 2370 away from 2610, we end up with 240.
Fetch the next digit (2) from the dividend, attach it to 240 and continue: 2402 / 790

On to step 6:
The number 790 fits into 2402 3 times, leaving a remainder of 32.
Put 3 as the next digit of the answer. 
Result so far: 1033.0
If we subtract 2370 from 2402, we get 32.
Grab the next digit (2) from the dividend, add it to 32, then carry on: 322 / 790

Advancing to step 7:
The number 790 fits into 322 0 times, leaving a remainder of 322.
Record the quotient 0 as the next digit in the result. 
Result so far: 10330.0
Subtract 0 from 322 to get 322.
Bring next digit (2) of the dividend behind the 322 and repeat the process: 3222 / 790

On to step 8:
When dividing 3222 by 790, we get 4 with a remainder of 62.
The number 4 becomes the next digit in our result. 
Result so far: 103304.0
If we take 3160 away from 3222, we end up with 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Moving on to step 9:
The number 790 fits into 620 0 times, leaving a remainder of 620.
Write down 0 as next digit of the result. 
Result so far: 103304.0
Deduct 0 from 620 and we're left with 620.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6200, and continue the process.

Advancing to step 10:
790 can be fit into 6200 7 times, resulting in a remainder of 670.
The number 7 becomes the next digit in our result. 
Result so far: 103304.07
The remainder is 670 after subtracting 5530 from 6200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6700, and continue the process.

On to step 11:
When dividing 6700 by 790, we get 8 with a remainder of 380.
Write down 8 as next digit of the result. 
Result so far: 103304.078
If we take 6320 away from 6700, we end up with 380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3800, and continue the process.

Step 12:
790 can be fit into 3800 4 times, resulting in a remainder of 640.
The next digit of our result is 4. 
Result so far: 103304.0784
Deduct 3160 from 3800 and we're left with 640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6400, and continue the process.

Going ahead to step 13:
790 goes into 6400 8 times with a remainder of 80.
Write down 8 as next digit of the result. 
Result so far: 103304.07848
If we subtract 6320 from 6400, we get 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

On to step 14:
800 divided by 790 is 1 with a remainder of 10.
Put 1 as the next digit of the answer. 
Result so far: 103304.078481
Subtract 790 from 800 to get 10.
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 790, we get 0 and a remainder of 100.
Record the quotient 0 as the next digit in the result. 
Result so far: 103304.078481
Subtracting 0 from 100 leaves us 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.

Going ahead to step 16:
If we divide 1000 by 790, we get 1 and a remainder of 210.
Put 1 as the next digit of the answer. 
Result so far: 103304.07848101
Subtracting 790 from 1000 leaves us with 210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2100, and continue the process.

The quotient of the division is 103304.07848101, and the remainder is 2.1e-07.
