73021 divided by 31 
We're looking to find how many times 31 goes into 73021.

Advancing to step 1:
The number 31 fits into 7 0 times, leaving a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Bring next digit (3) of the dividend behind the 7 and repeat the process: 73 / 31

Moving on to step 2:
The number 31 fits into 73 2 times, leaving a remainder of 11.
Put 2 as the next digit of the answer. 
Result so far: 2.0
The remainder is 11 after subtracting 62 from 73.
Grab the next digit (0) from the dividend, add it to 11, then carry on: 110 / 31

Advancing to step 3:
110 divided by 31 is 3 with a remainder of 17.
Put 3 as the next digit of the answer. 
Result so far: 23.0
The remainder is 17 after subtracting 93 from 110.
Append the next digit (2) from the dividend to 17 and continue with: 172 / 31

Let's proceed to step 4:
172 divided by 31 is 5 with a remainder of 17.
Record the quotient 5 as the next digit in the result. 
Result so far: 235.0
Subtract 155 from 172 to get 17.
Take the next digit (1) from the dividend and append it to 17, then repeat: 171 / 31

Step 5:
If we divide 171 by 31, we get 5 and a remainder of 16.
The number 5 becomes the next digit in our result. 
Result so far: 2355.0
Deduct 155 from 171 and we're left with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Advancing to step 6:
If we divide 160 by 31, we get 5 and a remainder of 5.
Put 5 as the next digit of the answer. 
Result so far: 2355.5
Subtract 155 from 160 to get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Let's proceed to step 7:
If we divide 50 by 31, we get 1 and a remainder of 19.
The number 1 becomes the next digit in our result. 
Result so far: 2355.51
Deduct 31 from 50 and we're left with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Step 8:
When dividing 190 by 31, we get 6 with a remainder of 4.
Record the quotient 6 as the next digit in the result. 
Result so far: 2355.516
If we take 186 away from 190, we end up 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.

Step 9:
If we divide 40 by 31, we get 1 and a remainder of 9.
The number 1 becomes the next digit in our result. 
Result so far: 2355.5161
Subtracting 31 from 40 leaves us 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.

Advancing to step 10:
31 goes into 90 2 times with a remainder of 28.
Record the quotient 2 as the next digit in the result. 
Result so far: 2355.51612
If we take 62 away from 90, we end up 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 11:
The number 31 fits into 280 9 times, leaving a remainder of 1.
Record the quotient 9 as the next digit in the result. 
Result so far: 2355.516129
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.

Moving on to step 12:
31 can be fit into 10 0 times, resulting in a remainder of 10.
The next digit of our result is 0. 
Result so far: 2355.516129
If we take 0 away from 10, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 13:
31 can be fit into 100 3 times, resulting in a remainder of 7.
The number 3 becomes the next digit in our result. 
Result so far: 2355.51612903
Subtracting 93 from 100 leaves us with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Our division results in 2355.51612903 with a remaining 7e-09.
