45845654 ÷ 691 
Our goal is to divide 45845654 by 691.

Advancing to step 1:
The number 691 fits into 4 0 times, leaving a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Grab the next digit (5) from the dividend, add it to 4, then carry on: 45 / 691

Step 2:
If we divide 45 by 691, we get 0 and a remainder of 45.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 45 after subtracting 0 from 45.
Append the next digit (8) from the dividend to 45 and continue with: 458 / 691

Advancing to step 3:
If we divide 458 by 691, we get 0 and a remainder of 458.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 458, we end up with 458.
Fetch the next digit (4) from the dividend, attach it to 458 and continue: 4584 / 691

Moving on to step 4:
691 can be fit into 4584 6 times, resulting in a remainder of 438.
Use 6 as the next digit of our solution. 
Result so far: 6.0
Subtracting 4146 from 4584 leaves us with 438.
Take the next digit (5) from the dividend and append it to 438, then repeat: 4385 / 691

Moving on to step 5:
The number 691 fits into 4385 6 times, leaving a remainder of 239.
Use 6 as the next digit of our solution. 
Result so far: 66.0
The remainder is 239 after subtracting 4146 from 4385.
Include the next digit (6) from the dividend after 239, then repeat: 2396 / 691

Advancing to step 6:
691 goes into 2396 3 times with a remainder of 323.
Use 3 as the next digit of our solution. 
Result so far: 663.0
If we take 2073 away from 2396, we end up with 323.
Include the next digit (5) from the dividend after 323, then repeat: 3235 / 691

Step 7:
691 can be fit into 3235 4 times, resulting in a remainder of 471.
Write down 4 as next digit of the result. 
Result so far: 6634.0
If we take 2764 away from 3235, we end up with 471.
Grab the next digit (4) from the dividend, add it to 471, then carry on: 4714 / 691

Going ahead to step 8:
The number 691 fits into 4714 6 times, leaving a remainder of 568.
Record the quotient 6 as the next digit in the result. 
Result so far: 66346.0
The remainder is 568 after subtracting 4146 from 4714.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5680, and continue the process.

Advancing to step 9:
When dividing 5680 by 691, we get 8 with a remainder of 152.
Write down 8 as next digit of the result. 
Result so far: 66346.8
Subtract 5528 from 5680 to get 152.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1520, and continue the process.

Advancing to step 10:
When dividing 1520 by 691, we get 2 with a remainder of 138.
The next digit of our result is 2. 
Result so far: 66346.82
If we subtract 1382 from 1520, we get 138.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1380, and continue the process.

Advancing to step 11:
691 can be fit into 1380 1 times, resulting in a remainder of 689.
Record the quotient 1 as the next digit in the result. 
Result so far: 66346.821
Subtracting 691 from 1380 leaves us with 689.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6890, and continue the process.

Let's proceed to step 12:
691 can be fit into 6890 9 times, resulting in a remainder of 671.
Write down 9 as next digit of the result. 
Result so far: 66346.8219
The remainder is 671 after subtracting 6219 from 6890.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6710, and continue the process.

Moving on to step 13:
691 goes into 6710 9 times with a remainder of 491.
Use 9 as the next digit of our solution. 
Result so far: 66346.82199
Subtract 6219 from 6710 to get 491.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4910, and continue the process.

Our division results in 66346.82199 with a remaining 0.000491.
