67498584 divided by 681 
The aim is to understand the frequency of 681 in 67498584.

Let's proceed to step 1:
681 goes into 6 0 times with a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Append the next digit (7) from the dividend to 6 and continue with: 67 / 681

Let's proceed to step 2:
681 can be fit into 67 0 times, resulting in a remainder of 67.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 67, we end up with 67.
Fetch the next digit (4) from the dividend, attach it to 67 and continue: 674 / 681

Moving on to step 3:
The number 681 fits into 674 0 times, leaving a remainder of 674.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 674, we get 674.
Take the next digit (9) from the dividend and append it to 674, then repeat: 6749 / 681

Let's proceed to step 4:
If we divide 6749 by 681, we get 9 and a remainder of 620.
Write down 9 as next digit of the result. 
Result so far: 9.0
If we subtract 6129 from 6749, we get 620.
Fetch the next digit (8) from the dividend, attach it to 620 and continue: 6208 / 681

Moving on to step 5:
6208 divided by 681 is 9 with a remainder of 79.
The next digit of our result is 9. 
Result so far: 99.0
If we subtract 6129 from 6208, we get 79.
Include the next digit (5) from the dividend after 79, then repeat: 795 / 681

Going ahead to step 6:
681 can be fit into 795 1 times, resulting in a remainder of 114.
The number 1 becomes the next digit in our result. 
Result so far: 991.0
If we subtract 681 from 795, we get 114.
Take the next digit (8) from the dividend and append it to 114, then repeat: 1148 / 681

Moving on to step 7:
681 can be fit into 1148 1 times, resulting in a remainder of 467.
Record the quotient 1 as the next digit in the result. 
Result so far: 9911.0
Subtracting 681 from 1148 leaves us with 467.
Take the next digit (4) from the dividend and append it to 467, then repeat: 4674 / 681

Let's proceed to step 8:
If we divide 4674 by 681, we get 6 and a remainder of 588.
The next digit of our result is 6. 
Result so far: 99116.0
The remainder is 588 after subtracting 4086 from 4674.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5880, and continue the process.

Let's proceed to step 9:
The number 681 fits into 5880 8 times, leaving a remainder of 432.
Put 8 as the next digit of the answer. 
Result so far: 99116.8
Deduct 5448 from 5880 and we're left with 432.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4320, and continue the process.

Going ahead to step 10:
If we divide 4320 by 681, we get 6 and a remainder of 234.
Record the quotient 6 as the next digit in the result. 
Result so far: 99116.86
If we subtract 4086 from 4320, we get 234.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2340, and continue the process.

On to step 11:
681 can be fit into 2340 3 times, resulting in a remainder of 297.
The number 3 becomes the next digit in our result. 
Result so far: 99116.863
Subtracting 2043 from 2340 leaves us with 297.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2970, and continue the process.

Advancing to step 12:
681 can be fit into 2970 4 times, resulting in a remainder of 246.
Use 4 as the next digit of our solution. 
Result so far: 99116.8634
The remainder is 246 after subtracting 2724 from 2970.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2460, and continue the process.

Step 13:
681 can be fit into 2460 3 times, resulting in a remainder of 417.
The number 3 becomes the next digit in our result. 
Result so far: 99116.86343
Subtract 2043 from 2460 to get 417.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4170, and continue the process.

On to step 14:
When dividing 4170 by 681, we get 6 with a remainder of 84.
The next digit of our result is 6. 
Result so far: 99116.863436
Deduct 4086 from 4170 and we're left with 84.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

Going ahead to step 15:
If we divide 840 by 681, we get 1 and a remainder of 159.
The next digit of our result is 1. 
Result so far: 99116.8634361
Deduct 681 from 840 and we're left with 159.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1590, and continue the process.

On to step 16:
1590 divided by 681 is 2 with a remainder of 228.
Use 2 as the next digit of our solution. 
Result so far: 99116.86343612
If we take 1362 away from 1590, we end up with 228.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2280, and continue the process.

The final outcome is 99116.86343612, with a leftover of 2.28e-07.
