We divide 30871038 by 210
We're looking to find how many times 210 goes into 30871038.

Let's proceed to step 1:
When dividing 3 by 210, we get 0 with a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Grab the next digit (0) from the dividend, add it to 3, then carry on: 30 / 210

On to step 2:
When dividing 30 by 210, we get 0 with a remainder of 30.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 30 leaves us with 30.
Take the next digit (8) from the dividend and append it to 30, then repeat: 308 / 210

Advancing to step 3:
210 can be fit into 308 1 times, resulting in a remainder of 98.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtracting 210 from 308 leaves us with 98.
Fetch the next digit (7) from the dividend, attach it to 98 and continue: 987 / 210

Advancing to step 4:
210 goes into 987 4 times with a remainder of 147.
The number 4 becomes the next digit in our result. 
Result so far: 14.0
Subtract 840 from 987 to get 147.
Include the next digit (1) from the dividend after 147, then repeat: 1471 / 210

Step 5:
1471 divided by 210 is 7 with a remainder of 1.
The number 7 becomes the next digit in our result. 
Result so far: 147.0
Subtract 1470 from 1471 to get 1.
Include the next digit (0) from the dividend after 1, then repeat: 10 / 210

On to step 6:
When dividing 10 by 210, we get 0 with a remainder of 10.
The number 0 becomes the next digit in our result. 
Result so far: 1470.0
If we subtract 0 from 10, we get 10.
Grab the next digit (3) from the dividend, add it to 10, then carry on: 103 / 210

On to step 7:
The number 210 fits into 103 0 times, leaving a remainder of 103.
Record the quotient 0 as the next digit in the result. 
Result so far: 14700.0
Subtract 0 from 103 to get 103.
Fetch the next digit (8) from the dividend, attach it to 103 and continue: 1038 / 210

On to step 8:
1038 divided by 210 is 4 with a remainder of 198.
Write down 4 as next digit of the result. 
Result so far: 147004.0
Deduct 840 from 1038 and we're left with 198.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1980, and continue the process.

Step 9:
210 goes into 1980 9 times with a remainder of 90.
Write down 9 as next digit of the result. 
Result so far: 147004.9
Deduct 1890 from 1980 and we're left with 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

On to step 10:
If we divide 900 by 210, we get 4 and a remainder of 60.
The number 4 becomes the next digit in our result. 
Result so far: 147004.94
Deduct 840 from 900 and we're left 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.

Advancing to step 11:
210 goes into 600 2 times with a remainder of 180.
The number 2 becomes the next digit in our result. 
Result so far: 147004.942
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.

Moving on to step 12:
If we divide 1800 by 210, we get 8 and a remainder of 120.
Use 8 as the next digit of our solution. 
Result so far: 147004.9428
If we subtract 1680 from 1800, 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.

On to step 13:
1200 divided by 210 is 5 with a remainder of 150.
The next digit of our result is 5. 
Result so far: 147004.94285
Subtract 1050 from 1200 to get 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

Let's proceed to step 14:
210 goes into 1500 7 times with a remainder of 30.
The number 7 becomes the next digit in our result. 
Result so far: 147004.942857
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.

Going ahead to step 15:
If we divide 300 by 210, we get 1 and a remainder of 90.
The next digit of our result is 1. 
Result so far: 147004.9428571
Subtract 210 from 300 to 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.

On to step 16:
If we divide 900 by 210, we get 4 and a remainder of 60.
Record the quotient 4 as the next digit in the result. 
Result so far: 147004.94285714
If we subtract 840 from 900, we get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

After the division, we end up with 147004.94285714 and a remainder of 6e-08.
