61929838 ÷ 210 
We want to divide 61929838 by 210.

Going ahead to step 1:
210 can be fit into 6 0 times, resulting in a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Take the next digit (1) from the dividend and append it to 6, then repeat: 61 / 210

Let's proceed to step 2:
210 goes into 61 0 times with a remainder of 61.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 61 after subtracting 0 from 61.
Take the next digit (9) from the dividend and append it to 61, then repeat: 619 / 210

Step 3:
210 goes into 619 2 times with a remainder of 199.
The next digit of our result is 2. 
Result so far: 2.0
The remainder is 199 after subtracting 420 from 619.
Append the next digit (2) from the dividend to 199 and continue with: 1992 / 210

Step 4:
When dividing 1992 by 210, we get 9 with a remainder of 102.
Put 9 as the next digit of the answer. 
Result so far: 29.0
If we subtract 1890 from 1992, we get 102.
Grab the next digit (9) from the dividend, add it to 102, then carry on: 1029 / 210

On to step 5:
210 can be fit into 1029 4 times, resulting in a remainder of 189.
The next digit of our result is 4. 
Result so far: 294.0
Deduct 840 from 1029 and we're left with 189.
Include the next digit (8) from the dividend after 189, then repeat: 1898 / 210

Let's proceed to step 6:
The number 210 fits into 1898 9 times, leaving a remainder of 8.
Put 9 as the next digit of the answer. 
Result so far: 2949.0
If we subtract 1890 from 1898, we get 8.
Fetch the next digit (3) from the dividend, attach it to 8 and continue: 83 / 210

On to step 7:
The number 210 fits into 83 0 times, leaving a remainder of 83.
Record the quotient 0 as the next digit in the result. 
Result so far: 29490.0
Deduct 0 from 83 and we're left with 83.
Grab the next digit (8) from the dividend, add it to 83, then carry on: 838 / 210

Advancing to step 8:
When dividing 838 by 210, we get 3 with a remainder of 208.
Use 3 as the next digit of our solution. 
Result so far: 294903.0
Subtract 630 from 838 to get 208.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2080, and continue the process.

On to step 9:
If we divide 2080 by 210, we get 9 and a remainder of 190.
The number 9 becomes the next digit in our result. 
Result so far: 294903.9
Subtract 1890 from 2080 to get 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1900, and continue the process.

Advancing to step 10:
When dividing 1900 by 210, we get 9 with a remainder of 10.
The next digit of our result is 9. 
Result so far: 294903.99
If we subtract 1890 from 1900, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

The quotient of the division is 294903.99, and the remainder is 0.01.
