7558727 divided by 789 
The aim is to understand the frequency of 789 in 7558727.

Step 1:
If we divide 7 by 789, we get 0 and a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Bring next digit (5) of the dividend behind the 7 and repeat the process: 75 / 789

Advancing to step 2:
If we divide 75 by 789, we get 0 and a remainder of 75.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 75, we get 75.
Grab the next digit (5) from the dividend, add it to 75, then carry on: 755 / 789

Going ahead to step 3:
The number 789 fits into 755 0 times, leaving a remainder of 755.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 755 after subtracting 0 from 755.
Take the next digit (8) from the dividend and append it to 755, then repeat: 7558 / 789

Going ahead to step 4:
When dividing 7558 by 789, we get 9 with a remainder of 457.
The next digit of our result is 9. 
Result so far: 9.0
Subtracting 7101 from 7558 leaves us with 457.
Take the next digit (7) from the dividend and append it to 457, then repeat: 4577 / 789

On to step 5:
4577 divided by 789 is 5 with a remainder of 632.
Record the quotient 5 as the next digit in the result. 
Result so far: 95.0
The remainder is 632 after subtracting 3945 from 4577.
Take the next digit (2) from the dividend and append it to 632, then repeat: 6322 / 789

On to step 6:
6322 divided by 789 is 8 with a remainder of 10.
Put 8 as the next digit of the answer. 
Result so far: 958.0
If we subtract 6312 from 6322, we get 10.
Append the next digit (7) from the dividend to 10 and continue with: 107 / 789

Going ahead to step 7:
When dividing 107 by 789, we get 0 with a remainder of 107.
The number 0 becomes the next digit in our result. 
Result so far: 9580.0
If we subtract 0 from 107, we get 107.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1070, and continue the process.

Moving on to step 8:
When dividing 1070 by 789, we get 1 with a remainder of 281.
The number 1 becomes the next digit in our result. 
Result so far: 9580.1
If we take 789 away from 1070, we end up with 281.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2810, and continue the process.

Moving on to step 9:
If we divide 2810 by 789, we get 3 and a remainder of 443.
Put 3 as the next digit of the answer. 
Result so far: 9580.13
If we take 2367 away from 2810, we end up with 443.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4430, and continue the process.

Advancing to step 10:
789 goes into 4430 5 times with a remainder of 485.
The next digit of our result is 5. 
Result so far: 9580.135
Subtract 3945 from 4430 to get 485.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4850, and continue the process.

Moving on to step 11:
789 can be fit into 4850 6 times, resulting in a remainder of 116.
Record the quotient 6 as the next digit in the result. 
Result so far: 9580.1356
Subtract 4734 from 4850 to get 116.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1160, and continue the process.

On to step 12:
1160 divided by 789 is 1 with a remainder of 371.
The next digit of our result is 1. 
Result so far: 9580.13561
If we take 789 away from 1160, we end up with 371.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3710, and continue the process.

Step 13:
3710 divided by 789 is 4 with a remainder of 554.
Record the quotient 4 as the next digit in the result. 
Result so far: 9580.135614
The remainder is 554 after subtracting 3156 from 3710.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5540, and continue the process.

Step 14:
5540 divided by 789 is 7 with a remainder of 17.
Put 7 as the next digit of the answer. 
Result so far: 9580.1356147
Subtract 5523 from 5540 to get 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

On to step 15:
If we divide 170 by 789, we get 0 and a remainder of 170.
Use 0 as the next digit of our solution. 
Result so far: 9580.1356147
The remainder is 170 after subtracting 0 from 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1700, and continue the process.

The quotient of the division is 9580.1356147, and the remainder is 1.7e-07.
