We divide 70773143 by 789
The aim is to understand the frequency of 789 in 70773143.

Advancing to step 1:
789 can be fit into 7 0 times, resulting in a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Bring next digit (0) of the dividend behind the 7 and repeat the process: 70 / 789

Moving on to step 2:
789 can be fit into 70 0 times, resulting in a remainder of 70.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 70, we get 70.
Append the next digit (7) from the dividend to 70 and continue with: 707 / 789

On to step 3:
707 divided by 789 is 0 with a remainder of 707.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 707 and we're left with 707.
Include the next digit (7) from the dividend after 707, then repeat: 7077 / 789

Advancing to step 4:
When dividing 7077 by 789, we get 8 with a remainder of 765.
Record the quotient 8 as the next digit in the result. 
Result so far: 8.0
Subtract 6312 from 7077 to get 765.
Append the next digit (3) from the dividend to 765 and continue with: 7653 / 789

Going ahead to step 5:
789 can be fit into 7653 9 times, resulting in a remainder of 552.
Record the quotient 9 as the next digit in the result. 
Result so far: 89.0
If we subtract 7101 from 7653, we get 552.
Grab the next digit (1) from the dividend, add it to 552, then carry on: 5521 / 789

Step 6:
789 goes into 5521 6 times with a remainder of 787.
The number 6 becomes the next digit in our result. 
Result so far: 896.0
Deduct 4734 from 5521 and we're left with 787.
Append the next digit (4) from the dividend to 787 and continue with: 7874 / 789

Step 7:
The number 789 fits into 7874 9 times, leaving a remainder of 773.
Record the quotient 9 as the next digit in the result. 
Result so far: 8969.0
If we subtract 7101 from 7874, we get 773.
Grab the next digit (3) from the dividend, add it to 773, then carry on: 7733 / 789

Step 8:
789 can be fit into 7733 9 times, resulting in a remainder of 632.
The number 9 becomes the next digit in our result. 
Result so far: 89699.0
Subtracting 7101 from 7733 leaves us with 632.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6320, and continue the process.

Step 9:
789 goes into 6320 8 times with a remainder of 8.
Use 8 as the next digit of our solution. 
Result so far: 89699.8
If we take 6312 away from 6320, we end up with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Step 10:
When dividing 80 by 789, we get 0 with a remainder of 80.
The number 0 becomes the next digit in our result. 
Result so far: 89699.8
Subtracting 0 from 80 leaves us with 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 11:
The number 789 fits into 800 1 times, leaving a remainder of 11.
Write down 1 as next digit of the result. 
Result so far: 89699.801
The remainder is 11 after subtracting 789 from 800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Step 12:
789 can be fit into 110 0 times, resulting in a remainder of 110.
Record the quotient 0 as the next digit in the result. 
Result so far: 89699.801
If we take 0 away from 110, we end up with 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1100, and continue the process.

On to step 13:
789 goes into 1100 1 times with a remainder of 311.
Record the quotient 1 as the next digit in the result. 
Result so far: 89699.80101
Subtract 789 from 1100 to get 311.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3110, and continue the process.

Going ahead to step 14:
The number 789 fits into 3110 3 times, leaving a remainder of 743.
Record the quotient 3 as the next digit in the result. 
Result so far: 89699.801013
If we take 2367 away from 3110, we end up with 743.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7430, and continue the process.

On to step 15:
789 goes into 7430 9 times with a remainder of 329.
Use 9 as the next digit of our solution. 
Result so far: 89699.8010139
If we take 7101 away from 7430, we end up with 329.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3290, and continue the process.

Let's proceed to step 16:
3290 divided by 789 is 4 with a remainder of 134.
Put 4 as the next digit of the answer. 
Result so far: 89699.80101394
If we take 3156 away from 3290, we end up with 134.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1340, and continue the process.

The final result is 89699.80101394 with a remainder of 1.34e-07.
