19911993 ÷ 693 
Our goal is to divide 19911993 by 693.

Advancing to step 1:
The number 693 fits into 1 0 times, leaving a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Take the next digit (9) from the dividend and append it to 1, then repeat: 19 / 693

On to step 2:
693 goes into 19 0 times with a remainder of 19.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 19 leaves us with 19.
Append the next digit (9) from the dividend to 19 and continue with: 199 / 693

On to step 3:
If we divide 199 by 693, we get 0 and a remainder of 199.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 199, we get 199.
Take the next digit (1) from the dividend and append it to 199, then repeat: 1991 / 693

On to step 4:
693 goes into 1991 2 times with a remainder of 605.
Write down 2 as next digit of the result. 
Result so far: 2.0
If we subtract 1386 from 1991, we get 605.
Fetch the next digit (1) from the dividend, attach it to 605 and continue: 6051 / 693

On to step 5:
693 goes into 6051 8 times with a remainder of 507.
Record the quotient 8 as the next digit in the result. 
Result so far: 28.0
If we subtract 5544 from 6051, we get 507.
Take the next digit (9) from the dividend and append it to 507, then repeat: 5079 / 693

Advancing to step 6:
693 goes into 5079 7 times with a remainder of 228.
The number 7 becomes the next digit in our result. 
Result so far: 287.0
If we take 4851 away from 5079, we end up with 228.
Include the next digit (9) from the dividend after 228, then repeat: 2289 / 693

Moving on to step 7:
When dividing 2289 by 693, we get 3 with a remainder of 210.
Record the quotient 3 as the next digit in the result. 
Result so far: 2873.0
If we take 2079 away from 2289, we end up with 210.
Append the next digit (3) from the dividend to 210 and continue with: 2103 / 693

Step 8:
693 can be fit into 2103 3 times, resulting in a remainder of 24.
Record the quotient 3 as the next digit in the result. 
Result so far: 28733.0
Subtracting 2079 from 2103 leaves us with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Going ahead to step 9:
693 goes into 240 0 times with a remainder of 240.
Record the quotient 0 as the next digit in the result. 
Result so far: 28733.0
If we subtract 0 from 240, we get 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

On to step 10:
693 can be fit into 2400 3 times, resulting in a remainder of 321.
The number 3 becomes the next digit in our result. 
Result so far: 28733.03
Subtract 2079 from 2400 to get 321.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3210, and continue the process.

Moving on to step 11:
3210 divided by 693 is 4 with a remainder of 438.
Use 4 as the next digit of our solution. 
Result so far: 28733.034
Subtract 2772 from 3210 to get 438.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4380, and continue the process.

Going ahead to step 12:
693 goes into 4380 6 times with a remainder of 222.
Put 6 as the next digit of the answer. 
Result so far: 28733.0346
If we take 4158 away from 4380, we end up with 222.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2220, and continue the process.

Step 13:
693 goes into 2220 3 times with a remainder of 141.
Record the quotient 3 as the next digit in the result. 
Result so far: 28733.03463
The remainder is 141 after subtracting 2079 from 2220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1410, and continue the process.

Step 14:
If we divide 1410 by 693, we get 2 and a remainder of 24.
Put 2 as the next digit of the answer. 
Result so far: 28733.034632
If we take 1386 away from 1410, we end up with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Advancing to step 15:
693 goes into 240 0 times with a remainder of 240.
The next digit of our result is 0. 
Result so far: 28733.034632
If we subtract 0 from 240, we get 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

On to step 16:
If we divide 2400 by 693, we get 3 and a remainder of 321.
The number 3 becomes the next digit in our result. 
Result so far: 28733.03463203
If we subtract 2079 from 2400, we get 321.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3210, and continue the process.

In conclusion, the division gives 28733.03463203 with a balance of 3.21e-07.
