Let's divide 73224351 by 210
We want to divide 73224351 by 210.

Let's proceed to step 1:
7 divided by 210 is 0 with a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Fetch the next digit (3) from the dividend, attach it to 7 and continue: 73 / 210

Advancing to step 2:
If we divide 73 by 210, we get 0 and a remainder of 73.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 73 to get 73.
Fetch the next digit (2) from the dividend, attach it to 73 and continue: 732 / 210

Let's proceed to step 3:
When dividing 732 by 210, we get 3 with a remainder of 102.
Put 3 as the next digit of the answer. 
Result so far: 3.0
If we take 630 away from 732, we end up with 102.
Take the next digit (2) from the dividend and append it to 102, then repeat: 1022 / 210

On to step 4:
If we divide 1022 by 210, we get 4 and a remainder of 182.
Put 4 as the next digit of the answer. 
Result so far: 34.0
Deduct 840 from 1022 and we're left with 182.
Fetch the next digit (4) from the dividend, attach it to 182 and continue: 1824 / 210

Let's proceed to step 5:
If we divide 1824 by 210, we get 8 and a remainder of 144.
Put 8 as the next digit of the answer. 
Result so far: 348.0
If we take 1680 away from 1824, we end up with 144.
Append the next digit (3) from the dividend to 144 and continue with: 1443 / 210

Let's proceed to step 6:
When dividing 1443 by 210, we get 6 with a remainder of 183.
Write down 6 as next digit of the result. 
Result so far: 3486.0
Deduct 1260 from 1443 and we're left with 183.
Append the next digit (5) from the dividend to 183 and continue with: 1835 / 210

Step 7:
If we divide 1835 by 210, we get 8 and a remainder of 155.
Use 8 as the next digit of our solution. 
Result so far: 34868.0
Subtracting 1680 from 1835 leaves us with 155.
Fetch the next digit (1) from the dividend, attach it to 155 and continue: 1551 / 210

Step 8:
The number 210 fits into 1551 7 times, leaving a remainder of 81.
The next digit of our result is 7. 
Result so far: 348687.0
If we subtract 1470 from 1551, we get 81.
Since there are no more digits in the dividend, we add a zero to the remainder making it 810, and continue the process.

Advancing to step 9:
When dividing 810 by 210, we get 3 with a remainder of 180.
The number 3 becomes the next digit in our result. 
Result so far: 348687.3
Subtracting 630 from 810 leaves us 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.

Let's proceed to step 10:
When dividing 1800 by 210, we get 8 with a remainder of 120.
Write down 8 as next digit of the result. 
Result so far: 348687.38
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.

On to step 11:
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: 348687.385
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.

Moving on to step 12:
210 can be fit into 1500 7 times, resulting in a remainder of 30.
Record the quotient 7 as the next digit in the result. 
Result so far: 348687.3857
Deduct 1470 from 1500 and we're left 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.

Let's proceed to step 13:
If we divide 300 by 210, we get 1 and a remainder of 90.
Write down 1 as next digit of the result. 
Result so far: 348687.38571
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.

Step 14:
900 divided by 210 is 4 with a remainder of 60.
Record the quotient 4 as the next digit in the result. 
Result so far: 348687.385714
If we take 840 away from 900, we end up 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.

Step 15:
The number 210 fits into 600 2 times, leaving a remainder of 180.
Write down 2 as next digit of the result. 
Result so far: 348687.3857142
Deduct 420 from 600 and we're left 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 16:
When dividing 1800 by 210, we get 8 with a remainder of 120.
Write down 8 as next digit of the result. 
Result so far: 348687.38571428
Subtracting 1680 from 1800 leaves us 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.

The final result is 348687.38571428 with a remainder of 1.2e-07.
