Let's divide 61137874 by 321
Let's see how many times 321 fits into 61137874.

On to step 1:
321 can be fit into 6 0 times, resulting in a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Grab the next digit (1) from the dividend, add it to 6, then carry on: 61 / 321

Going ahead to step 2:
61 divided by 321 is 0 with a remainder of 61.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 61, we get 61.
Append the next digit (1) from the dividend to 61 and continue with: 611 / 321

Step 3:
When dividing 611 by 321, we get 1 with a remainder of 290.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we subtract 321 from 611, we get 290.
Append the next digit (3) from the dividend to 290 and continue with: 2903 / 321

Moving on to step 4:
If we divide 2903 by 321, we get 9 and a remainder of 14.
The number 9 becomes the next digit in our result. 
Result so far: 19.0
If we subtract 2889 from 2903, we get 14.
Grab the next digit (7) from the dividend, add it to 14, then carry on: 147 / 321

Moving on to step 5:
The number 321 fits into 147 0 times, leaving a remainder of 147.
Use 0 as the next digit of our solution. 
Result so far: 190.0
The remainder is 147 after subtracting 0 from 147.
Fetch the next digit (8) from the dividend, attach it to 147 and continue: 1478 / 321

Advancing to step 6:
321 goes into 1478 4 times with a remainder of 194.
Use 4 as the next digit of our solution. 
Result so far: 1904.0
Deduct 1284 from 1478 and we're left with 194.
Take the next digit (7) from the dividend and append it to 194, then repeat: 1947 / 321

Advancing to step 7:
321 can be fit into 1947 6 times, resulting in a remainder of 21.
Use 6 as the next digit of our solution. 
Result so far: 19046.0
Subtracting 1926 from 1947 leaves us with 21.
Bring next digit (4) of the dividend behind the 21 and repeat the process: 214 / 321

Let's proceed to step 8:
If we divide 214 by 321, we get 0 and a remainder of 214.
Use 0 as the next digit of our solution. 
Result so far: 190460.0
The remainder is 214 after subtracting 0 from 214.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2140, and continue the process.

Advancing to step 9:
When dividing 2140 by 321, we get 6 with a remainder of 214.
The next digit of our result is 6. 
Result so far: 190460.6
The remainder is 214 after subtracting 1926 from 2140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2140, and continue the process.

Going ahead to step 10:
The number 321 fits into 2140 6 times, leaving a remainder of 214.
Record the quotient 6 as the next digit in the result. 
Result so far: 190460.66
If we take 1926 away from 2140, we end up with 214.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2140, and continue the process.

The quotient of the division is 190460.66, and the remainder is 0.214.
