We divide 72004203 by 210
We're looking to find how many times 210 goes into 72004203.

Let's proceed to step 1:
7 divided by 210 is 0 with a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Fetch the next digit (2) from the dividend, attach it to 7 and continue: 72 / 210

Step 2:
72 divided by 210 is 0 with a remainder of 72.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 72 leaves us with 72.
Grab the next digit (0) from the dividend, add it to 72, then carry on: 720 / 210

Moving on to step 3:
210 goes into 720 3 times with a remainder of 90.
Use 3 as the next digit of our solution. 
Result so far: 3.0
Subtract 630 from 720 to get 90.
Fetch the next digit (0) from the dividend, attach it to 90 and continue: 900 / 210

Advancing to step 4:
210 goes into 900 4 times with a remainder of 60.
The number 4 becomes the next digit in our result. 
Result so far: 34.0
Subtract 840 from 900 to get 60.
Include the next digit (4) from the dividend after 60, then repeat: 604 / 210

Advancing to step 5:
The number 210 fits into 604 2 times, leaving a remainder of 184.
The number 2 becomes the next digit in our result. 
Result so far: 342.0
The remainder is 184 after subtracting 420 from 604.
Take the next digit (2) from the dividend and append it to 184, then repeat: 1842 / 210

Let's proceed to step 6:
210 can be fit into 1842 8 times, resulting in a remainder of 162.
Record the quotient 8 as the next digit in the result. 
Result so far: 3428.0
The remainder is 162 after subtracting 1680 from 1842.
Include the next digit (0) from the dividend after 162, then repeat: 1620 / 210

Moving on to step 7:
1620 divided by 210 is 7 with a remainder of 150.
Use 7 as the next digit of our solution. 
Result so far: 34287.0
If we subtract 1470 from 1620, we get 150.
Grab the next digit (3) from the dividend, add it to 150, then carry on: 1503 / 210

Step 8:
When dividing 1503 by 210, we get 7 with a remainder of 33.
Record the quotient 7 as the next digit in the result. 
Result so far: 342877.0
If we take 1470 away from 1503, we end up with 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Advancing to step 9:
The number 210 fits into 330 1 times, leaving a remainder of 120.
Use 1 as the next digit of our solution. 
Result so far: 342877.1
If we subtract 210 from 330, we get 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Step 10:
The number 210 fits into 1200 5 times, leaving a remainder of 150.
The number 5 becomes the next digit in our result. 
Result so far: 342877.15
If we take 1050 away from 1200, we end up with 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

Advancing to step 11:
If we divide 1500 by 210, we get 7 and a remainder of 30.
Write down 7 as next digit of the result. 
Result so far: 342877.157
Subtracting 1470 from 1500 leaves us with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Advancing to step 12:
When dividing 300 by 210, we get 1 with a remainder of 90.
Put 1 as the next digit of the answer. 
Result so far: 342877.1571
If we subtract 210 from 300, we get 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

Advancing to step 13:
210 can be fit into 900 4 times, resulting in a remainder of 60.
The number 4 becomes the next digit in our result. 
Result so far: 342877.15714
Subtracting 840 from 900 leaves us with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Going ahead to step 14:
210 goes into 600 2 times with a remainder of 180.
Write down 2 as next digit of the result. 
Result so far: 342877.157142
If we take 420 away from 600, we end up with 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

Step 15:
If we divide 1800 by 210, we get 8 and a remainder of 120.
Put 8 as the next digit of the answer. 
Result so far: 342877.1571428
Deduct 1680 from 1800 and we're left with 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Let's proceed to step 16:
If we divide 1200 by 210, we get 5 and a remainder of 150.
Record the quotient 5 as the next digit in the result. 
Result so far: 342877.15714285
Subtracting 1050 from 1200 leaves us with 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

After the division, we end up with 342877.15714285 and a remainder of 1.5e-07.
