15615706 divided by 789 
The aim is to understand the frequency of 789 in 15615706.

Let's proceed to step 1:
789 can be fit into 1 0 times, resulting in a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Bring next digit (5) of the dividend behind the 1 and repeat the process: 15 / 789

Advancing to step 2:
789 can be fit into 15 0 times, resulting in a remainder of 15.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 15 after subtracting 0 from 15.
Fetch the next digit (6) from the dividend, attach it to 15 and continue: 156 / 789

Going ahead to step 3:
789 can be fit into 156 0 times, resulting in a remainder of 156.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 156 and we're left with 156.
Take the next digit (1) from the dividend and append it to 156, then repeat: 1561 / 789

Moving on to step 4:
If we divide 1561 by 789, we get 1 and a remainder of 772.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Deduct 789 from 1561 and we're left with 772.
Grab the next digit (5) from the dividend, add it to 772, then carry on: 7725 / 789

Let's proceed to step 5:
7725 divided by 789 is 9 with a remainder of 624.
Put 9 as the next digit of the answer. 
Result so far: 19.0
Subtracting 7101 from 7725 leaves us with 624.
Include the next digit (7) from the dividend after 624, then repeat: 6247 / 789

Advancing to step 6:
789 can be fit into 6247 7 times, resulting in a remainder of 724.
Record the quotient 7 as the next digit in the result. 
Result so far: 197.0
Subtracting 5523 from 6247 leaves us with 724.
Append the next digit (0) from the dividend to 724 and continue with: 7240 / 789

On to step 7:
789 can be fit into 7240 9 times, resulting in a remainder of 139.
Write down 9 as next digit of the result. 
Result so far: 1979.0
Subtracting 7101 from 7240 leaves us with 139.
Append the next digit (6) from the dividend to 139 and continue with: 1396 / 789

Step 8:
789 can be fit into 1396 1 times, resulting in a remainder of 607.
Put 1 as the next digit of the answer. 
Result so far: 19791.0
Deduct 789 from 1396 and we're left with 607.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6070, and continue the process.

Advancing to step 9:
If we divide 6070 by 789, we get 7 and a remainder of 547.
Use 7 as the next digit of our solution. 
Result so far: 19791.7
Subtract 5523 from 6070 to get 547.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5470, and continue the process.

On to step 10:
5470 divided by 789 is 6 with a remainder of 736.
The number 6 becomes the next digit in our result. 
Result so far: 19791.76
The remainder is 736 after subtracting 4734 from 5470.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7360, and continue the process.

Step 11:
789 can be fit into 7360 9 times, resulting in a remainder of 259.
The next digit of our result is 9. 
Result so far: 19791.769
If we take 7101 away from 7360, we end up with 259.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2590, and continue the process.

On to step 12:
789 goes into 2590 3 times with a remainder of 223.
Write down 3 as next digit of the result. 
Result so far: 19791.7693
If we take 2367 away from 2590, we end up with 223.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2230, and continue the process.

Step 13:
When dividing 2230 by 789, we get 2 with a remainder of 652.
Record the quotient 2 as the next digit in the result. 
Result so far: 19791.76932
If we take 1578 away from 2230, we end up with 652.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6520, and continue the process.

Step 14:
789 can be fit into 6520 8 times, resulting in a remainder of 208.
Write down 8 as next digit of the result. 
Result so far: 19791.769328
If we subtract 6312 from 6520, we get 208.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2080, and continue the process.

Going ahead to step 15:
When dividing 2080 by 789, we get 2 with a remainder of 502.
Use 2 as the next digit of our solution. 
Result so far: 19791.7693282
If we subtract 1578 from 2080, we get 502.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5020, and continue the process.

Advancing to step 16:
789 goes into 5020 6 times with a remainder of 286.
Record the quotient 6 as the next digit in the result. 
Result so far: 19791.76932826
Subtracting 4734 from 5020 leaves us with 286.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2860, and continue the process.

The final result is 19791.76932826 with a remainder of 2.86e-07.
