64685138 divided by 691 
We want to divide 64685138 by 691.

Let's proceed to step 1:
If we divide 6 by 691, we get 0 and a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Append the next digit (4) from the dividend to 6 and continue with: 64 / 691

Advancing to step 2:
When dividing 64 by 691, we get 0 with a remainder of 64.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 64, we get 64.
Take the next digit (6) from the dividend and append it to 64, then repeat: 646 / 691

Going ahead to step 3:
691 can be fit into 646 0 times, resulting in a remainder of 646.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 646 after subtracting 0 from 646.
Grab the next digit (8) from the dividend, add it to 646, then carry on: 6468 / 691

On to step 4:
691 goes into 6468 9 times with a remainder of 249.
Use 9 as the next digit of our solution. 
Result so far: 9.0
Deduct 6219 from 6468 and we're left with 249.
Append the next digit (5) from the dividend to 249 and continue with: 2495 / 691

On to step 5:
The number 691 fits into 2495 3 times, leaving a remainder of 422.
Use 3 as the next digit of our solution. 
Result so far: 93.0
Subtract 2073 from 2495 to get 422.
Include the next digit (1) from the dividend after 422, then repeat: 4221 / 691

Advancing to step 6:
691 goes into 4221 6 times with a remainder of 75.
The number 6 becomes the next digit in our result. 
Result so far: 936.0
The remainder is 75 after subtracting 4146 from 4221.
Bring next digit (3) of the dividend behind the 75 and repeat the process: 753 / 691

Moving on to step 7:
If we divide 753 by 691, we get 1 and a remainder of 62.
Write down 1 as next digit of the result. 
Result so far: 9361.0
Deduct 691 from 753 and we're left with 62.
Fetch the next digit (8) from the dividend, attach it to 62 and continue: 628 / 691

Going ahead to step 8:
691 can be fit into 628 0 times, resulting in a remainder of 628.
Write down 0 as next digit of the result. 
Result so far: 93610.0
Subtract 0 from 628 to get 628.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6280, and continue the process.

Moving on to step 9:
691 goes into 6280 9 times with a remainder of 61.
Put 9 as the next digit of the answer. 
Result so far: 93610.9
If we subtract 6219 from 6280, we get 61.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

Let's proceed to step 10:
If we divide 610 by 691, we get 0 and a remainder of 610.
The number 0 becomes the next digit in our result. 
Result so far: 93610.9
Subtracting 0 from 610 leaves us with 610.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6100, and continue the process.

Let's proceed to step 11:
691 goes into 6100 8 times with a remainder of 572.
Put 8 as the next digit of the answer. 
Result so far: 93610.908
If we take 5528 away from 6100, we end up with 572.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5720, and continue the process.

Let's proceed to step 12:
691 goes into 5720 8 times with a remainder of 192.
Put 8 as the next digit of the answer. 
Result so far: 93610.9088
Subtract 5528 from 5720 to get 192.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1920, and continue the process.

The final result is 93610.9088 with a remainder of 0.00192.
