We're dividing 85402489 by 783 
The aim is to understand the frequency of 783 in 85402489.

Let's proceed to step 1:
783 can be fit into 8 0 times, resulting in a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Take the next digit (5) from the dividend and append it to 8, then repeat: 85 / 783

Let's proceed to step 2:
783 can be fit into 85 0 times, resulting in a remainder of 85.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 85 after subtracting 0 from 85.
Include the next digit (4) from the dividend after 85, then repeat: 854 / 783

Moving on to step 3:
854 divided by 783 is 1 with a remainder of 71.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
The remainder is 71 after subtracting 783 from 854.
Bring next digit (0) of the dividend behind the 71 and repeat the process: 710 / 783

Going ahead to step 4:
710 divided by 783 is 0 with a remainder of 710.
Write down 0 as next digit of the result. 
Result so far: 10.0
Subtracting 0 from 710 leaves us with 710.
Grab the next digit (2) from the dividend, add it to 710, then carry on: 7102 / 783

Step 5:
783 goes into 7102 9 times with a remainder of 55.
The number 9 becomes the next digit in our result. 
Result so far: 109.0
If we subtract 7047 from 7102, we get 55.
Append the next digit (4) from the dividend to 55 and continue with: 554 / 783

On to step 6:
If we divide 554 by 783, we get 0 and a remainder of 554.
Record the quotient 0 as the next digit in the result. 
Result so far: 1090.0
Deduct 0 from 554 and we're left with 554.
Grab the next digit (8) from the dividend, add it to 554, then carry on: 5548 / 783

Moving on to step 7:
783 goes into 5548 7 times with a remainder of 67.
Record the quotient 7 as the next digit in the result. 
Result so far: 10907.0
If we take 5481 away from 5548, we end up with 67.
Append the next digit (9) from the dividend to 67 and continue with: 679 / 783

Going ahead to step 8:
783 goes into 679 0 times with a remainder of 679.
Use 0 as the next digit of our solution. 
Result so far: 109070.0
Subtract 0 from 679 to get 679.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6790, and continue the process.

Let's proceed to step 9:
When dividing 6790 by 783, we get 8 with a remainder of 526.
Record the quotient 8 as the next digit in the result. 
Result so far: 109070.8
Deduct 6264 from 6790 and we're left with 526.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5260, and continue the process.

Going ahead to step 10:
783 goes into 5260 6 times with a remainder of 562.
Put 6 as the next digit of the answer. 
Result so far: 109070.86
Deduct 4698 from 5260 and we're left with 562.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5620, and continue the process.

Going ahead to step 11:
783 can be fit into 5620 7 times, resulting in a remainder of 139.
Record the quotient 7 as the next digit in the result. 
Result so far: 109070.867
Subtract 5481 from 5620 to get 139.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1390, and continue the process.

On to step 12:
The number 783 fits into 1390 1 times, leaving a remainder of 607.
The number 1 becomes the next digit in our result. 
Result so far: 109070.8671
Deduct 783 from 1390 and we're left with 607.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6070, and continue the process.

Step 13:
If we divide 6070 by 783, we get 7 and a remainder of 589.
Record the quotient 7 as the next digit in the result. 
Result so far: 109070.86717
Subtract 5481 from 6070 to get 589.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5890, and continue the process.

Let's proceed to step 14:
When dividing 5890 by 783, we get 7 with a remainder of 409.
The number 7 becomes the next digit in our result. 
Result so far: 109070.867177
If we subtract 5481 from 5890, we get 409.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4090, and continue the process.

The quotient of the division is 109070.867177, and the remainder is 4.09e-05.
