57525171 ÷ 784 
The aim is to understand the frequency of 784 in 57525171.

Going ahead to step 1:
When dividing 5 by 784, we get 0 with a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Grab the next digit (7) from the dividend, add it to 5, then carry on: 57 / 784

Let's proceed to step 2:
If we divide 57 by 784, we get 0 and a remainder of 57.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 57, we end up with 57.
Fetch the next digit (5) from the dividend, attach it to 57 and continue: 575 / 784

On to step 3:
If we divide 575 by 784, we get 0 and a remainder of 575.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 575, we end up with 575.
Grab the next digit (2) from the dividend, add it to 575, then carry on: 5752 / 784

Step 4:
784 can be fit into 5752 7 times, resulting in a remainder of 264.
Put 7 as the next digit of the answer. 
Result so far: 7.0
Deduct 5488 from 5752 and we're left with 264.
Grab the next digit (5) from the dividend, add it to 264, then carry on: 2645 / 784

On to step 5:
If we divide 2645 by 784, we get 3 and a remainder of 293.
Use 3 as the next digit of our solution. 
Result so far: 73.0
Subtract 2352 from 2645 to get 293.
Append the next digit (1) from the dividend to 293 and continue with: 2931 / 784

Advancing to step 6:
The number 784 fits into 2931 3 times, leaving a remainder of 579.
Record the quotient 3 as the next digit in the result. 
Result so far: 733.0
If we take 2352 away from 2931, we end up with 579.
Take the next digit (7) from the dividend and append it to 579, then repeat: 5797 / 784

Going ahead to step 7:
5797 divided by 784 is 7 with a remainder of 309.
The number 7 becomes the next digit in our result. 
Result so far: 7337.0
If we take 5488 away from 5797, we end up with 309.
Take the next digit (1) from the dividend and append it to 309, then repeat: 3091 / 784

Let's proceed to step 8:
3091 divided by 784 is 3 with a remainder of 739.
Record the quotient 3 as the next digit in the result. 
Result so far: 73373.0
Subtract 2352 from 3091 to get 739.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7390, and continue the process.

Let's proceed to step 9:
If we divide 7390 by 784, we get 9 and a remainder of 334.
Use 9 as the next digit of our solution. 
Result so far: 73373.9
If we take 7056 away from 7390, we end up with 334.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3340, and continue the process.

On to step 10:
3340 divided by 784 is 4 with a remainder of 204.
Use 4 as the next digit of our solution. 
Result so far: 73373.94
Deduct 3136 from 3340 and we're left with 204.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2040, and continue the process.

Advancing to step 11:
The number 784 fits into 2040 2 times, leaving a remainder of 472.
Record the quotient 2 as the next digit in the result. 
Result so far: 73373.942
Subtract 1568 from 2040 to get 472.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4720, and continue the process.

On to step 12:
784 goes into 4720 6 times with a remainder of 16.
Put 6 as the next digit of the answer. 
Result so far: 73373.9426
Subtracting 4704 from 4720 leaves us with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Going ahead to step 13:
784 goes into 160 0 times with a remainder of 160.
The next digit of our result is 0. 
Result so far: 73373.9426
The remainder is 160 after subtracting 0 from 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Advancing to step 14:
If we divide 1600 by 784, we get 2 and a remainder of 32.
Use 2 as the next digit of our solution. 
Result so far: 73373.942602
Deduct 1568 from 1600 and we're left with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Let's proceed to step 15:
When dividing 320 by 784, we get 0 with a remainder of 320.
Write down 0 as next digit of the result. 
Result so far: 73373.942602
Subtracting 0 from 320 leaves us with 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

Step 16:
When dividing 3200 by 784, we get 4 with a remainder of 64.
Write down 4 as next digit of the result. 
Result so far: 73373.94260204
If we subtract 3136 from 3200, we get 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

After the division, we end up with 73373.94260204 and a remainder of 6.4e-08.
