Let's divide 78832520 by 210
Let's see how many times 210 fits into 78832520.

Moving on to step 1:
210 can be fit into 7 0 times, resulting in a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Take the next digit (8) from the dividend and append it to 7, then repeat: 78 / 210

Moving on to step 2:
The number 210 fits into 78 0 times, leaving a remainder of 78.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 78 and we're left with 78.
Grab the next digit (8) from the dividend, add it to 78, then carry on: 788 / 210

Advancing to step 3:
If we divide 788 by 210, we get 3 and a remainder of 158.
The next digit of our result is 3. 
Result so far: 3.0
Deduct 630 from 788 and we're left with 158.
Append the next digit (3) from the dividend to 158 and continue with: 1583 / 210

On to step 4:
The number 210 fits into 1583 7 times, leaving a remainder of 113.
The number 7 becomes the next digit in our result. 
Result so far: 37.0
If we subtract 1470 from 1583, we get 113.
Append the next digit (2) from the dividend to 113 and continue with: 1132 / 210

Step 5:
210 can be fit into 1132 5 times, resulting in a remainder of 82.
The next digit of our result is 5. 
Result so far: 375.0
Subtract 1050 from 1132 to get 82.
Fetch the next digit (5) from the dividend, attach it to 82 and continue: 825 / 210

Advancing to step 6:
When dividing 825 by 210, we get 3 with a remainder of 195.
The number 3 becomes the next digit in our result. 
Result so far: 3753.0
Subtracting 630 from 825 leaves us with 195.
Bring next digit (2) of the dividend behind the 195 and repeat the process: 1952 / 210

Step 7:
1952 divided by 210 is 9 with a remainder of 62.
The number 9 becomes the next digit in our result. 
Result so far: 37539.0
Subtracting 1890 from 1952 leaves us with 62.
Fetch the next digit (0) from the dividend, attach it to 62 and continue: 620 / 210

Let's proceed to step 8:
If we divide 620 by 210, we get 2 and a remainder of 200.
The next digit of our result is 2. 
Result so far: 375392.0
The remainder is 200 after subtracting 420 from 620.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

Moving on to step 9:
2000 divided by 210 is 9 with a remainder of 110.
Put 9 as the next digit of the answer. 
Result so far: 375392.9
Subtract 1890 from 2000 to get 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1100, and continue the process.

Step 10:
The number 210 fits into 1100 5 times, leaving a remainder of 50.
The number 5 becomes the next digit in our result. 
Result so far: 375392.95
If we take 1050 away from 1100, we end up with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Moving on to step 11:
The number 210 fits into 500 2 times, leaving a remainder of 80.
Record the quotient 2 as the next digit in the result. 
Result so far: 375392.952
Subtracting 420 from 500 leaves us with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Going ahead to step 12:
210 can be fit into 800 3 times, resulting in a remainder of 170.
The number 3 becomes the next digit in our result. 
Result so far: 375392.9523
The remainder is 170 after subtracting 630 from 800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1700, and continue the process.

Moving on to step 13:
The number 210 fits into 1700 8 times, leaving a remainder of 20.
Use 8 as the next digit of our solution. 
Result so far: 375392.95238
Subtracting 1680 from 1700 leaves us with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

On to step 14:
200 divided by 210 is 0 with a remainder of 200.
Use 0 as the next digit of our solution. 
Result so far: 375392.95238
Deduct 0 from 200 and we're left with 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

Advancing to step 15:
The number 210 fits into 2000 9 times, leaving a remainder of 110.
Use 9 as the next digit of our solution. 
Result so far: 375392.9523809
Subtract 1890 from 2000 to get 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1100, and continue the process.

Step 16:
The number 210 fits into 1100 5 times, leaving a remainder of 50.
Use 5 as the next digit of our solution. 
Result so far: 375392.95238095
The remainder is 50 after subtracting 1050 from 1100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Our division results in 375392.95238095 with a remaining 5e-08.
