We're dividing 34207680 by 691 
The aim is to understand the frequency of 691 in 34207680.

Step 1:
If we divide 3 by 691, we get 0 and a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Grab the next digit (4) from the dividend, add it to 3, then carry on: 34 / 691

Let's proceed to step 2:
When dividing 34 by 691, we get 0 with a remainder of 34.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 34 to get 34.
Take the next digit (2) from the dividend and append it to 34, then repeat: 342 / 691

Step 3:
691 goes into 342 0 times with a remainder of 342.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 342 and we're left with 342.
Fetch the next digit (0) from the dividend, attach it to 342 and continue: 3420 / 691

Step 4:
3420 divided by 691 is 4 with a remainder of 656.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
Subtract 2764 from 3420 to get 656.
Bring next digit (7) of the dividend behind the 656 and repeat the process: 6567 / 691

On to step 5:
691 can be fit into 6567 9 times, resulting in a remainder of 348.
The number 9 becomes the next digit in our result. 
Result so far: 49.0
Subtract 6219 from 6567 to get 348.
Fetch the next digit (6) from the dividend, attach it to 348 and continue: 3486 / 691

Going ahead to step 6:
When dividing 3486 by 691, we get 5 with a remainder of 31.
Write down 5 as next digit of the result. 
Result so far: 495.0
If we take 3455 away from 3486, we end up with 31.
Take the next digit (8) from the dividend and append it to 31, then repeat: 318 / 691

Advancing to step 7:
318 divided by 691 is 0 with a remainder of 318.
Use 0 as the next digit of our solution. 
Result so far: 4950.0
If we take 0 away from 318, we end up with 318.
Grab the next digit (0) from the dividend, add it to 318, then carry on: 3180 / 691

Advancing to step 8:
The number 691 fits into 3180 4 times, leaving a remainder of 416.
The next digit of our result is 4. 
Result so far: 49504.0
If we subtract 2764 from 3180, we get 416.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4160, and continue the process.

Let's proceed to step 9:
When dividing 4160 by 691, we get 6 with a remainder of 14.
Write down 6 as next digit of the result. 
Result so far: 49504.6
If we subtract 4146 from 4160, we get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Step 10:
691 goes into 140 0 times with a remainder of 140.
Write down 0 as next digit of the result. 
Result so far: 49504.6
If we subtract 0 from 140, we get 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

On to step 11:
If we divide 1400 by 691, we get 2 and a remainder of 18.
The next digit of our result is 2. 
Result so far: 49504.602
If we subtract 1382 from 1400, we get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Step 12:
691 can be fit into 180 0 times, resulting in a remainder of 180.
Record the quotient 0 as the next digit in the result. 
Result so far: 49504.602
Subtract 0 from 180 to get 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

Going ahead to step 13:
The number 691 fits into 1800 2 times, leaving a remainder of 418.
Write down 2 as next digit of the result. 
Result so far: 49504.60202
If we take 1382 away from 1800, we end up with 418.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4180, and continue the process.

On to step 14:
If we divide 4180 by 691, we get 6 and a remainder of 34.
Put 6 as the next digit of the answer. 
Result so far: 49504.602026
The remainder is 34 after subtracting 4146 from 4180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Going ahead to step 15:
The number 691 fits into 340 0 times, leaving a remainder of 340.
Record the quotient 0 as the next digit in the result. 
Result so far: 49504.602026
If we subtract 0 from 340, we get 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3400, and continue the process.

On to step 16:
691 goes into 3400 4 times with a remainder of 636.
The number 4 becomes the next digit in our result. 
Result so far: 49504.60202604
Deduct 2764 from 3400 and we're left with 636.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6360, and continue the process.

The final outcome is 49504.60202604, with a leftover of 6.36e-07.
