43526407 ÷ 681 
The aim is to understand the frequency of 681 in 43526407.

Going ahead to step 1:
The number 681 fits into 4 0 times, leaving a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Grab the next digit (3) from the dividend, add it to 4, then carry on: 43 / 681

Advancing to step 2:
If we divide 43 by 681, we get 0 and a remainder of 43.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 43, we get 43.
Append the next digit (5) from the dividend to 43 and continue with: 435 / 681

Moving on to step 3:
681 can be fit into 435 0 times, resulting in a remainder of 435.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 435, we end up with 435.
Append the next digit (2) from the dividend to 435 and continue with: 4352 / 681

Going ahead to step 4:
When dividing 4352 by 681, we get 6 with a remainder of 266.
Record the quotient 6 as the next digit in the result. 
Result so far: 6.0
If we take 4086 away from 4352, we end up with 266.
Append the next digit (6) from the dividend to 266 and continue with: 2666 / 681

On to step 5:
681 can be fit into 2666 3 times, resulting in a remainder of 623.
Record the quotient 3 as the next digit in the result. 
Result so far: 63.0
Deduct 2043 from 2666 and we're left with 623.
Fetch the next digit (4) from the dividend, attach it to 623 and continue: 6234 / 681

Advancing to step 6:
The number 681 fits into 6234 9 times, leaving a remainder of 105.
Put 9 as the next digit of the answer. 
Result so far: 639.0
Deduct 6129 from 6234 and we're left with 105.
Take the next digit (0) from the dividend and append it to 105, then repeat: 1050 / 681

Let's proceed to step 7:
1050 divided by 681 is 1 with a remainder of 369.
Write down 1 as next digit of the result. 
Result so far: 6391.0
If we take 681 away from 1050, we end up with 369.
Bring next digit (7) of the dividend behind the 369 and repeat the process: 3697 / 681

Moving on to step 8:
The number 681 fits into 3697 5 times, leaving a remainder of 292.
Record the quotient 5 as the next digit in the result. 
Result so far: 63915.0
If we subtract 3405 from 3697, we get 292.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2920, and continue the process.

Step 9:
681 can be fit into 2920 4 times, resulting in a remainder of 196.
Write down 4 as next digit of the result. 
Result so far: 63915.4
Deduct 2724 from 2920 and we're left with 196.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1960, and continue the process.

Going ahead to step 10:
681 can be fit into 1960 2 times, resulting in a remainder of 598.
Put 2 as the next digit of the answer. 
Result so far: 63915.42
If we subtract 1362 from 1960, we get 598.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5980, and continue the process.

Step 11:
681 can be fit into 5980 8 times, resulting in a remainder of 532.
Record the quotient 8 as the next digit in the result. 
Result so far: 63915.428
Subtracting 5448 from 5980 leaves us with 532.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5320, and continue the process.

On to step 12:
When dividing 5320 by 681, we get 7 with a remainder of 553.
Use 7 as the next digit of our solution. 
Result so far: 63915.4287
If we take 4767 away from 5320, we end up with 553.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5530, and continue the process.

On to step 13:
681 can be fit into 5530 8 times, resulting in a remainder of 82.
The number 8 becomes the next digit in our result. 
Result so far: 63915.42878
The remainder is 82 after subtracting 5448 from 5530.
Since there are no more digits in the dividend, we add a zero to the remainder making it 820, and continue the process.

Moving on to step 14:
820 divided by 681 is 1 with a remainder of 139.
Use 1 as the next digit of our solution. 
Result so far: 63915.428781
If we subtract 681 from 820, we 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.

Step 15:
If we divide 1390 by 681, we get 2 and a remainder of 28.
Record the quotient 2 as the next digit in the result. 
Result so far: 63915.4287812
If we subtract 1362 from 1390, we get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Going ahead to step 16:
If we divide 280 by 681, we get 0 and a remainder of 280.
Record the quotient 0 as the next digit in the result. 
Result so far: 63915.4287812
Subtracting 0 from 280 leaves us with 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

The quotient of the division is 63915.4287812, and the remainder is 2.8e-07.
