64385543 divided by 691 
Our goal is to divide 64385543 by 691.

Going ahead to step 1:
691 can be fit into 6 0 times, resulting in a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Take the next digit (4) from the dividend and append it to 6, then repeat: 64 / 691

Step 2:
If we divide 64 by 691, we get 0 and a remainder of 64.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 64 to get 64.
Take the next digit (3) from the dividend and append it to 64, then repeat: 643 / 691

On to step 3:
691 can be fit into 643 0 times, resulting in a remainder of 643.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 643 after subtracting 0 from 643.
Grab the next digit (8) from the dividend, add it to 643, then carry on: 6438 / 691

Step 4:
The number 691 fits into 6438 9 times, leaving a remainder of 219.
Record the quotient 9 as the next digit in the result. 
Result so far: 9.0
Deduct 6219 from 6438 and we're left with 219.
Fetch the next digit (5) from the dividend, attach it to 219 and continue: 2195 / 691

Step 5:
When dividing 2195 by 691, we get 3 with a remainder of 122.
The next digit of our result is 3. 
Result so far: 93.0
If we take 2073 away from 2195, we end up with 122.
Take the next digit (5) from the dividend and append it to 122, then repeat: 1225 / 691

Step 6:
1225 divided by 691 is 1 with a remainder of 534.
The next digit of our result is 1. 
Result so far: 931.0
If we take 691 away from 1225, we end up with 534.
Grab the next digit (4) from the dividend, add it to 534, then carry on: 5344 / 691

Let's proceed to step 7:
The number 691 fits into 5344 7 times, leaving a remainder of 507.
Put 7 as the next digit of the answer. 
Result so far: 9317.0
If we subtract 4837 from 5344, we get 507.
Take the next digit (3) from the dividend and append it to 507, then repeat: 5073 / 691

Going ahead to step 8:
5073 divided by 691 is 7 with a remainder of 236.
Put 7 as the next digit of the answer. 
Result so far: 93177.0
Subtracting 4837 from 5073 leaves us with 236.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2360, and continue the process.

Going ahead to step 9:
When dividing 2360 by 691, we get 3 with a remainder of 287.
Use 3 as the next digit of our solution. 
Result so far: 93177.3
If we subtract 2073 from 2360, we get 287.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2870, and continue the process.

Moving on to step 10:
691 goes into 2870 4 times with a remainder of 106.
Write down 4 as next digit of the result. 
Result so far: 93177.34
The remainder is 106 after subtracting 2764 from 2870.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1060, and continue the process.

Let's proceed to step 11:
1060 divided by 691 is 1 with a remainder of 369.
Use 1 as the next digit of our solution. 
Result so far: 93177.341
Subtracting 691 from 1060 leaves us with 369.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3690, and continue the process.

Step 12:
691 can be fit into 3690 5 times, resulting in a remainder of 235.
Put 5 as the next digit of the answer. 
Result so far: 93177.3415
Deduct 3455 from 3690 and we're left with 235.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2350, and continue the process.

Advancing to step 13:
When dividing 2350 by 691, we get 3 with a remainder of 277.
The number 3 becomes the next digit in our result. 
Result so far: 93177.34153
If we take 2073 away from 2350, we end up with 277.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2770, and continue the process.

Advancing to step 14:
2770 divided by 691 is 4 with a remainder of 6.
Use 4 as the next digit of our solution. 
Result so far: 93177.341534
Subtract 2764 from 2770 to get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

On to step 15:
60 divided by 691 is 0 with a remainder of 60.
The next digit of our result is 0. 
Result so far: 93177.341534
If we take 0 away from 60, we end up with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Going ahead to step 16:
If we divide 600 by 691, we get 0 and a remainder of 600.
Record the quotient 0 as the next digit in the result. 
Result so far: 93177.341534
If we subtract 0 from 600, we get 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6000, and continue the process.

After the division, we end up with 93177.341534 and a remainder of 6e-07.
