57984498 ÷ 680 
The aim is to understand the frequency of 680 in 57984498.

Going ahead to step 1:
When dividing 5 by 680, we get 0 with a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Append the next digit (7) from the dividend to 5 and continue with: 57 / 680

Advancing to step 2:
57 divided by 680 is 0 with a remainder of 57.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 57 and we're left with 57.
Fetch the next digit (9) from the dividend, attach it to 57 and continue: 579 / 680

Step 3:
579 divided by 680 is 0 with a remainder of 579.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 579, we end up with 579.
Append the next digit (8) from the dividend to 579 and continue with: 5798 / 680

On to step 4:
If we divide 5798 by 680, we get 8 and a remainder of 358.
Record the quotient 8 as the next digit in the result. 
Result so far: 8.0
Deduct 5440 from 5798 and we're left with 358.
Include the next digit (4) from the dividend after 358, then repeat: 3584 / 680

Advancing to step 5:
680 can be fit into 3584 5 times, resulting in a remainder of 184.
Record the quotient 5 as the next digit in the result. 
Result so far: 85.0
If we take 3400 away from 3584, we end up with 184.
Grab the next digit (4) from the dividend, add it to 184, then carry on: 1844 / 680

Going ahead to step 6:
1844 divided by 680 is 2 with a remainder of 484.
Record the quotient 2 as the next digit in the result. 
Result so far: 852.0
If we subtract 1360 from 1844, we get 484.
Take the next digit (9) from the dividend and append it to 484, then repeat: 4849 / 680

Going ahead to step 7:
When dividing 4849 by 680, we get 7 with a remainder of 89.
The next digit of our result is 7. 
Result so far: 8527.0
The remainder is 89 after subtracting 4760 from 4849.
Bring next digit (8) of the dividend behind the 89 and repeat the process: 898 / 680

Step 8:
The number 680 fits into 898 1 times, leaving a remainder of 218.
Record the quotient 1 as the next digit in the result. 
Result so far: 85271.0
Subtracting 680 from 898 leaves us with 218.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2180, and continue the process.

On to step 9:
The number 680 fits into 2180 3 times, leaving a remainder of 140.
Use 3 as the next digit of our solution. 
Result so far: 85271.3
If we take 2040 away from 2180, we end up with 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

Moving on to step 10:
When dividing 1400 by 680, we get 2 with a remainder of 40.
The number 2 becomes the next digit in our result. 
Result so far: 85271.32
If we subtract 1360 from 1400, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Let's proceed to step 11:
The number 680 fits into 400 0 times, leaving a remainder of 400.
Use 0 as the next digit of our solution. 
Result so far: 85271.32
Deduct 0 from 400 and we're left with 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

On to step 12:
680 can be fit into 4000 5 times, resulting in a remainder of 600.
Write down 5 as next digit of the result. 
Result so far: 85271.3205
If we take 3400 away from 4000, we end up with 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6000, and continue the process.

Let's proceed to step 13:
6000 divided by 680 is 8 with a remainder of 560.
Record the quotient 8 as the next digit in the result. 
Result so far: 85271.32058
The remainder is 560 after subtracting 5440 from 6000.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5600, and continue the process.

On to step 14:
The number 680 fits into 5600 8 times, leaving a remainder of 160.
The next digit of our result is 8. 
Result so far: 85271.320588
The remainder is 160 after subtracting 5440 from 5600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

The final outcome is 85271.320588, with a leftover of 1.6e-05.
