We look at the division of 691645 by 31 
We're looking to find how many times 31 goes into 691645.

Moving on to step 1:
31 goes into 6 0 times with a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Fetch the next digit (9) from the dividend, attach it to 6 and continue: 69 / 31

Going ahead to step 2:
If we divide 69 by 31, we get 2 and a remainder of 7.
Use 2 as the next digit of our solution. 
Result so far: 2.0
Subtract 62 from 69 to get 7.
Append the next digit (1) from the dividend to 7 and continue with: 71 / 31

Going ahead to step 3:
When dividing 71 by 31, we get 2 with a remainder of 9.
The next digit of our result is 2. 
Result so far: 22.0
If we subtract 62 from 71, we get 9.
Take the next digit (6) from the dividend and append it to 9, then repeat: 96 / 31

Going ahead to step 4:
96 divided by 31 is 3 with a remainder of 3.
Write down 3 as next digit of the result. 
Result so far: 223.0
If we subtract 93 from 96, we get 3.
Take the next digit (4) from the dividend and append it to 3, then repeat: 34 / 31

Going ahead to step 5:
When dividing 34 by 31, we get 1 with a remainder of 3.
Use 1 as the next digit of our solution. 
Result so far: 2231.0
If we subtract 31 from 34, we get 3.
Include the next digit (5) from the dividend after 3, then repeat: 35 / 31

Let's proceed to step 6:
31 can be fit into 35 1 times, resulting in a remainder of 4.
Record the quotient 1 as the next digit in the result. 
Result so far: 22311.0
Subtracting 31 from 35 leaves us with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

On to step 7:
When dividing 40 by 31, we get 1 with a remainder of 9.
Use 1 as the next digit of our solution. 
Result so far: 22311.1
Deduct 31 from 40 and we're left with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Moving on to step 8:
90 divided by 31 is 2 with a remainder of 28.
The next digit of our result is 2. 
Result so far: 22311.12
Subtracting 62 from 90 leaves us with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Let's proceed to step 9:
280 divided by 31 is 9 with a remainder of 1.
Put 9 as the next digit of the answer. 
Result so far: 22311.129
If we take 279 away from 280, we end up with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Advancing to step 10:
31 can be fit into 10 0 times, resulting in a remainder of 10.
Put 0 as the next digit of the answer. 
Result so far: 22311.129
The remainder is 10 after subtracting 0 from 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 11:
100 divided by 31 is 3 with a remainder of 7.
Put 3 as the next digit of the answer. 
Result so far: 22311.12903
The remainder is 7 after subtracting 93 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Let's proceed to step 12:
31 can be fit into 70 2 times, resulting in a remainder of 8.
Use 2 as the next digit of our solution. 
Result so far: 22311.129032
Deduct 62 from 70 and we're left with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Let's proceed to step 13:
31 can be fit into 80 2 times, resulting in a remainder of 18.
The number 2 becomes the next digit in our result. 
Result so far: 22311.1290322
If we subtract 62 from 80, 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.

The final outcome is 22311.1290322, with a leftover of 1.8e-07.
