87723545 divided by 849 
The aim is to understand the frequency of 849 in 87723545.

On to step 1:
The number 849 fits into 8 0 times, leaving a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Grab the next digit (7) from the dividend, add it to 8, then carry on: 87 / 849

Moving on to step 2:
If we divide 87 by 849, we get 0 and a remainder of 87.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 87 to get 87.
Bring next digit (7) of the dividend behind the 87 and repeat the process: 877 / 849

Step 3:
When dividing 877 by 849, we get 1 with a remainder of 28.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Deduct 849 from 877 and we're left with 28.
Append the next digit (2) from the dividend to 28 and continue with: 282 / 849

On to step 4:
849 can be fit into 282 0 times, resulting in a remainder of 282.
Record the quotient 0 as the next digit in the result. 
Result so far: 10.0
Subtracting 0 from 282 leaves us with 282.
Grab the next digit (3) from the dividend, add it to 282, then carry on: 2823 / 849

Advancing to step 5:
849 can be fit into 2823 3 times, resulting in a remainder of 276.
Write down 3 as next digit of the result. 
Result so far: 103.0
Deduct 2547 from 2823 and we're left with 276.
Grab the next digit (5) from the dividend, add it to 276, then carry on: 2765 / 849

Step 6:
849 goes into 2765 3 times with a remainder of 218.
Use 3 as the next digit of our solution. 
Result so far: 1033.0
If we take 2547 away from 2765, we end up with 218.
Include the next digit (4) from the dividend after 218, then repeat: 2184 / 849

Step 7:
If we divide 2184 by 849, we get 2 and a remainder of 486.
Put 2 as the next digit of the answer. 
Result so far: 10332.0
If we subtract 1698 from 2184, we get 486.
Append the next digit (5) from the dividend to 486 and continue with: 4865 / 849

Advancing to step 8:
849 can be fit into 4865 5 times, resulting in a remainder of 620.
The next digit of our result is 5. 
Result so far: 103325.0
Subtracting 4245 from 4865 leaves us 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 9:
849 can be fit into 6200 7 times, resulting in a remainder of 257.
Put 7 as the next digit of the answer. 
Result so far: 103325.7
If we subtract 5943 from 6200, we get 257.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2570, and continue the process.

Going ahead to step 10:
The number 849 fits into 2570 3 times, leaving a remainder of 23.
Record the quotient 3 as the next digit in the result. 
Result so far: 103325.73
If we subtract 2547 from 2570, we get 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Advancing to step 11:
849 can be fit into 230 0 times, resulting in a remainder of 230.
Record the quotient 0 as the next digit in the result. 
Result so far: 103325.73
Subtract 0 from 230 to get 230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2300, and continue the process.

Step 12:
If we divide 2300 by 849, we get 2 and a remainder of 602.
Record the quotient 2 as the next digit in the result. 
Result so far: 103325.7302
The remainder is 602 after subtracting 1698 from 2300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6020, and continue the process.

Going ahead to step 13:
The number 849 fits into 6020 7 times, leaving a remainder of 77.
Write down 7 as next digit of the result. 
Result so far: 103325.73027
The remainder is 77 after subtracting 5943 from 6020.
Since there are no more digits in the dividend, we add a zero to the remainder making it 770, and continue the process.

Advancing to step 14:
770 divided by 849 is 0 with a remainder of 770.
The number 0 becomes the next digit in our result. 
Result so far: 103325.73027
If we take 0 away from 770, we end up with 770.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7700, and continue the process.

Advancing to step 15:
The number 849 fits into 7700 9 times, leaving a remainder of 59.
The number 9 becomes the next digit in our result. 
Result so far: 103325.7302709
If we subtract 7641 from 7700, we get 59.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

Moving on to step 16:
849 can be fit into 590 0 times, resulting in a remainder of 590.
Use 0 as the next digit of our solution. 
Result so far: 103325.7302709
The remainder is 590 after subtracting 0 from 590.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5900, and continue the process.

The final outcome is 103325.7302709, with a leftover of 5.9e-07.
