We're dividing 91853580 by 784 
The aim is to understand the frequency of 784 in 91853580.

Let's proceed to step 1:
When dividing 9 by 784, we get 0 with a remainder of 9.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 9 and we're left with 9.
Append the next digit (1) from the dividend to 9 and continue with: 91 / 784

Advancing to step 2:
784 goes into 91 0 times with a remainder of 91.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 91, we end up with 91.
Fetch the next digit (8) from the dividend, attach it to 91 and continue: 918 / 784

On to step 3:
If we divide 918 by 784, we get 1 and a remainder of 134.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtract 784 from 918 to get 134.
Grab the next digit (5) from the dividend, add it to 134, then carry on: 1345 / 784

Going ahead to step 4:
When dividing 1345 by 784, we get 1 with a remainder of 561.
Record the quotient 1 as the next digit in the result. 
Result so far: 11.0
Subtract 784 from 1345 to get 561.
Fetch the next digit (3) from the dividend, attach it to 561 and continue: 5613 / 784

Step 5:
The number 784 fits into 5613 7 times, leaving a remainder of 125.
Put 7 as the next digit of the answer. 
Result so far: 117.0
Subtract 5488 from 5613 to get 125.
Fetch the next digit (5) from the dividend, attach it to 125 and continue: 1255 / 784

Advancing to step 6:
The number 784 fits into 1255 1 times, leaving a remainder of 471.
Write down 1 as next digit of the result. 
Result so far: 1171.0
Deduct 784 from 1255 and we're left with 471.
Fetch the next digit (8) from the dividend, attach it to 471 and continue: 4718 / 784

Let's proceed to step 7:
If we divide 4718 by 784, we get 6 and a remainder of 14.
Write down 6 as next digit of the result. 
Result so far: 11716.0
Subtracting 4704 from 4718 leaves us with 14.
Fetch the next digit (0) from the dividend, attach it to 14 and continue: 140 / 784

Step 8:
140 divided by 784 is 0 with a remainder of 140.
The number 0 becomes the next digit in our result. 
Result so far: 117160.0
Subtract 0 from 140 to get 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

Advancing to step 9:
When dividing 1400 by 784, we get 1 with a remainder of 616.
Put 1 as the next digit of the answer. 
Result so far: 117160.1
If we subtract 784 from 1400, we get 616.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6160, and continue the process.

On to step 10:
If we divide 6160 by 784, we get 7 and a remainder of 672.
Use 7 as the next digit of our solution. 
Result so far: 117160.17
Deduct 5488 from 6160 and we're left with 672.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6720, and continue the process.

Let's proceed to step 11:
784 can be fit into 6720 8 times, resulting in a remainder of 448.
Put 8 as the next digit of the answer. 
Result so far: 117160.178
Subtract 6272 from 6720 to get 448.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4480, and continue the process.

Moving on to step 12:
When dividing 4480 by 784, we get 5 with a remainder of 560.
Record the quotient 5 as the next digit in the result. 
Result so far: 117160.1785
The remainder is 560 after subtracting 3920 from 4480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5600, and continue the process.

Going ahead to step 13:
784 goes into 5600 7 times with a remainder of 112.
Write down 7 as next digit of the result. 
Result so far: 117160.17857
Subtract 5488 from 5600 to get 112.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1120, and continue the process.

Going ahead to step 14:
1120 divided by 784 is 1 with a remainder of 336.
The number 1 becomes the next digit in our result. 
Result so far: 117160.178571
Deduct 784 from 1120 and we're left with 336.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3360, and continue the process.

Going ahead to step 15:
The number 784 fits into 3360 4 times, leaving a remainder of 224.
Write down 4 as next digit of the result. 
Result so far: 117160.1785714
Subtract 3136 from 3360 to get 224.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2240, and continue the process.

Going ahead to step 16:
The number 784 fits into 2240 2 times, leaving a remainder of 672.
The next digit of our result is 2. 
Result so far: 117160.17857142
If we subtract 1568 from 2240, we get 672.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6720, and continue the process.

The final result is 117160.17857142 with a remainder of 6.72e-07.
