We're dividing 61599956 by 819 
The aim is to understand the frequency of 819 in 61599956.

Step 1:
When dividing 6 by 819, we get 0 with a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Grab the next digit (1) from the dividend, add it to 6, then carry on: 61 / 819

On to step 2:
The number 819 fits into 61 0 times, leaving a remainder of 61.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 61, we end up with 61.
Fetch the next digit (5) from the dividend, attach it to 61 and continue: 615 / 819

Moving on to step 3:
When dividing 615 by 819, we get 0 with a remainder of 615.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 615 to get 615.
Append the next digit (9) from the dividend to 615 and continue with: 6159 / 819

Step 4:
819 can be fit into 6159 7 times, resulting in a remainder of 426.
The number 7 becomes the next digit in our result. 
Result so far: 7.0
Subtract 5733 from 6159 to get 426.
Bring next digit (9) of the dividend behind the 426 and repeat the process: 4269 / 819

Step 5:
The number 819 fits into 4269 5 times, leaving a remainder of 174.
The next digit of our result is 5. 
Result so far: 75.0
Subtracting 4095 from 4269 leaves us with 174.
Append the next digit (9) from the dividend to 174 and continue with: 1749 / 819

Moving on to step 6:
If we divide 1749 by 819, we get 2 and a remainder of 111.
Use 2 as the next digit of our solution. 
Result so far: 752.0
Subtracting 1638 from 1749 leaves us with 111.
Bring next digit (5) of the dividend behind the 111 and repeat the process: 1115 / 819

Let's proceed to step 7:
1115 divided by 819 is 1 with a remainder of 296.
Use 1 as the next digit of our solution. 
Result so far: 7521.0
If we subtract 819 from 1115, we get 296.
Append the next digit (6) from the dividend to 296 and continue with: 2966 / 819

Step 8:
When dividing 2966 by 819, we get 3 with a remainder of 509.
The next digit of our result is 3. 
Result so far: 75213.0
The remainder is 509 after subtracting 2457 from 2966.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5090, and continue the process.

Advancing to step 9:
5090 divided by 819 is 6 with a remainder of 176.
The next digit of our result is 6. 
Result so far: 75213.6
The remainder is 176 after subtracting 4914 from 5090.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1760, and continue the process.

Step 10:
The number 819 fits into 1760 2 times, leaving a remainder of 122.
The next digit of our result is 2. 
Result so far: 75213.62
If we take 1638 away from 1760, we end up with 122.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1220, and continue the process.

Going ahead to step 11:
If we divide 1220 by 819, we get 1 and a remainder of 401.
Use 1 as the next digit of our solution. 
Result so far: 75213.621
Subtracting 819 from 1220 leaves us with 401.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4010, and continue the process.

Let's proceed to step 12:
819 can be fit into 4010 4 times, resulting in a remainder of 734.
Write down 4 as next digit of the result. 
Result so far: 75213.6214
Deduct 3276 from 4010 and we're left with 734.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7340, and continue the process.

Advancing to step 13:
819 can be fit into 7340 8 times, resulting in a remainder of 788.
Record the quotient 8 as the next digit in the result. 
Result so far: 75213.62148
If we subtract 6552 from 7340, we get 788.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7880, and continue the process.

Advancing to step 14:
When dividing 7880 by 819, we get 9 with a remainder of 509.
The number 9 becomes the next digit in our result. 
Result so far: 75213.621489
If we subtract 7371 from 7880, we get 509.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5090, and continue the process.

Advancing to step 15:
819 goes into 5090 6 times with a remainder of 176.
The number 6 becomes the next digit in our result. 
Result so far: 75213.6214896
If we subtract 4914 from 5090, we get 176.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1760, and continue the process.

Let's proceed to step 16:
1760 divided by 819 is 2 with a remainder of 122.
Write down 2 as next digit of the result. 
Result so far: 75213.62148962
Subtract 1638 from 1760 to get 122.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1220, and continue the process.

The quotient of the division is 75213.62148962, and the remainder is 1.22e-07.
