858963 ÷ 53 
Let's see how many times 53 fits into 858963.

Step 1:
The number 53 fits into 8 0 times, leaving a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Grab the next digit (5) from the dividend, add it to 8, then carry on: 85 / 53

Let's proceed to step 2:
If we divide 85 by 53, we get 1 and a remainder of 32.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
The remainder is 32 after subtracting 53 from 85.
Include the next digit (8) from the dividend after 32, then repeat: 328 / 53

Step 3:
53 goes into 328 6 times with a remainder of 10.
Use 6 as the next digit of our solution. 
Result so far: 16.0
Deduct 318 from 328 and we're left with 10.
Grab the next digit (9) from the dividend, add it to 10, then carry on: 109 / 53

Going ahead to step 4:
109 divided by 53 is 2 with a remainder of 3.
Record the quotient 2 as the next digit in the result. 
Result so far: 162.0
If we subtract 106 from 109, we get 3.
Include the next digit (6) from the dividend after 3, then repeat: 36 / 53

Going ahead to step 5:
The number 53 fits into 36 0 times, leaving a remainder of 36.
Record the quotient 0 as the next digit in the result. 
Result so far: 1620.0
If we take 0 away from 36, we end up with 36.
Bring next digit (3) of the dividend behind the 36 and repeat the process: 363 / 53

Step 6:
When dividing 363 by 53, we get 6 with a remainder of 45.
The next digit of our result is 6. 
Result so far: 16206.0
Subtract 318 from 363 to get 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

On to step 7:
If we divide 450 by 53, we get 8 and a remainder of 26.
Record the quotient 8 as the next digit in the result. 
Result so far: 16206.8
Subtract 424 from 450 to get 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Step 8:
260 divided by 53 is 4 with a remainder of 48.
Put 4 as the next digit of the answer. 
Result so far: 16206.84
If we take 212 away from 260, we end up with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Step 9:
53 can be fit into 480 9 times, resulting in a remainder of 3.
Put 9 as the next digit of the answer. 
Result so far: 16206.849
If we subtract 477 from 480, we get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

On to step 10:
53 goes into 30 0 times with a remainder of 30.
Record the quotient 0 as the next digit in the result. 
Result so far: 16206.849
If we subtract 0 from 30, we get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

On to step 11:
53 goes into 300 5 times with a remainder of 35.
Use 5 as the next digit of our solution. 
Result so far: 16206.84905
Subtract 265 from 300 to get 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Let's proceed to step 12:
53 can be fit into 350 6 times, resulting in a remainder of 32.
Record the quotient 6 as the next digit in the result. 
Result so far: 16206.849056
Deduct 318 from 350 and we're left with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Let's proceed to step 13:
The number 53 fits into 320 6 times, leaving a remainder of 2.
Record the quotient 6 as the next digit in the result. 
Result so far: 16206.8490566
Subtract 318 from 320 to get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

The quotient of the division is 16206.8490566, and the remainder is 2e-08.
