1373399 ÷ 691 
We want to figure out the number of times 1373399 can be divided by 691.

Moving on to step 1:
691 can be fit into 1 0 times, resulting in a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Take the next digit (3) from the dividend and append it to 1, then repeat: 13 / 691

Advancing to step 2:
691 goes into 13 0 times with a remainder of 13.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 13 and we're left with 13.
Take the next digit (7) from the dividend and append it to 13, then repeat: 137 / 691

Moving on to step 3:
The number 691 fits into 137 0 times, leaving a remainder of 137.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 137 and we're left with 137.
Grab the next digit (3) from the dividend, add it to 137, then carry on: 1373 / 691

Moving on to step 4:
691 goes into 1373 1 times with a remainder of 682.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtract 691 from 1373 to get 682.
Fetch the next digit (3) from the dividend, attach it to 682 and continue: 6823 / 691

Step 5:
The number 691 fits into 6823 9 times, leaving a remainder of 604.
Use 9 as the next digit of our solution. 
Result so far: 19.0
Deduct 6219 from 6823 and we're left with 604.
Include the next digit (9) from the dividend after 604, then repeat: 6049 / 691

Moving on to step 6:
6049 divided by 691 is 8 with a remainder of 521.
Write down 8 as next digit of the result. 
Result so far: 198.0
Subtracting 5528 from 6049 leaves us with 521.
Bring next digit (9) of the dividend behind the 521 and repeat the process: 5219 / 691

Advancing to step 7:
691 goes into 5219 7 times with a remainder of 382.
The number 7 becomes the next digit in our result. 
Result so far: 1987.0
Subtract 4837 from 5219 to get 382.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3820, and continue the process.

Moving on to step 8:
691 can be fit into 3820 5 times, resulting in a remainder of 365.
The number 5 becomes the next digit in our result. 
Result so far: 1987.5
Deduct 3455 from 3820 and we're left with 365.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3650, and continue the process.

Step 9:
691 goes into 3650 5 times with a remainder of 195.
Use 5 as the next digit of our solution. 
Result so far: 1987.55
Deduct 3455 from 3650 and we're left with 195.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1950, and continue the process.

After the division, we end up with 1987.55 and a remainder of 0.195.
