61838402 ÷ 849 
The aim is to understand the frequency of 849 in 61838402.

Going ahead to step 1:
849 can be fit into 6 0 times, resulting in a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Fetch the next digit (1) from the dividend, attach it to 6 and continue: 61 / 849

Going ahead to step 2:
849 can be fit into 61 0 times, resulting in a remainder of 61.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 61 to get 61.
Append the next digit (8) from the dividend to 61 and continue with: 618 / 849

Let's proceed to step 3:
When dividing 618 by 849, we get 0 with a remainder of 618.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 618 after subtracting 0 from 618.
Append the next digit (3) from the dividend to 618 and continue with: 6183 / 849

Moving on to step 4:
The number 849 fits into 6183 7 times, leaving a remainder of 240.
The next digit of our result is 7. 
Result so far: 7.0
Subtract 5943 from 6183 to get 240.
Grab the next digit (8) from the dividend, add it to 240, then carry on: 2408 / 849

Moving on to step 5:
The number 849 fits into 2408 2 times, leaving a remainder of 710.
The next digit of our result is 2. 
Result so far: 72.0
If we take 1698 away from 2408, we end up with 710.
Take the next digit (4) from the dividend and append it to 710, then repeat: 7104 / 849

On to step 6:
When dividing 7104 by 849, we get 8 with a remainder of 312.
The number 8 becomes the next digit in our result. 
Result so far: 728.0
If we subtract 6792 from 7104, we get 312.
Append the next digit (0) from the dividend to 312 and continue with: 3120 / 849

Step 7:
849 can be fit into 3120 3 times, resulting in a remainder of 573.
The number 3 becomes the next digit in our result. 
Result so far: 7283.0
Deduct 2547 from 3120 and we're left with 573.
Take the next digit (2) from the dividend and append it to 573, then repeat: 5732 / 849

Advancing to step 8:
If we divide 5732 by 849, we get 6 and a remainder of 638.
Use 6 as the next digit of our solution. 
Result so far: 72836.0
Subtract 5094 from 5732 to get 638.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6380, and continue the process.

Advancing to step 9:
When dividing 6380 by 849, we get 7 with a remainder of 437.
The number 7 becomes the next digit in our result. 
Result so far: 72836.7
Subtracting 5943 from 6380 leaves us with 437.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4370, and continue the process.

Moving on to step 10:
The number 849 fits into 4370 5 times, leaving a remainder of 125.
Put 5 as the next digit of the answer. 
Result so far: 72836.75
The remainder is 125 after subtracting 4245 from 4370.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1250, and continue the process.

Let's proceed to step 11:
1250 divided by 849 is 1 with a remainder of 401.
Put 1 as the next digit of the answer. 
Result so far: 72836.751
If we subtract 849 from 1250, we get 401.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4010, and continue the process.

On to step 12:
849 goes into 4010 4 times with a remainder of 614.
The next digit of our result is 4. 
Result so far: 72836.7514
Subtract 3396 from 4010 to get 614.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6140, and continue the process.

On to step 13:
849 goes into 6140 7 times with a remainder of 197.
Use 7 as the next digit of our solution. 
Result so far: 72836.75147
Subtracting 5943 from 6140 leaves us with 197.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1970, and continue the process.

Going ahead to step 14:
The number 849 fits into 1970 2 times, leaving a remainder of 272.
The next digit of our result is 2. 
Result so far: 72836.751472
Subtracting 1698 from 1970 leaves us with 272.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2720, and continue the process.

Going ahead to step 15:
When dividing 2720 by 849, we get 3 with a remainder of 173.
Write down 3 as next digit of the result. 
Result so far: 72836.7514723
If we take 2547 away from 2720, we end up with 173.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1730, and continue the process.

Step 16:
849 goes into 1730 2 times with a remainder of 32.
Put 2 as the next digit of the answer. 
Result so far: 72836.75147232
Subtract 1698 from 1730 to get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

The final outcome is 72836.75147232, with a leftover of 3.2e-08.
