663691 ÷ 53 
We want to divide 663691 by 53.

Going ahead to step 1:
53 can be fit into 6 0 times, resulting in a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Grab the next digit (6) from the dividend, add it to 6, then carry on: 66 / 53

Let's proceed to step 2:
53 goes into 66 1 times with a remainder of 13.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtract 53 from 66 to get 13.
Bring next digit (3) of the dividend behind the 13 and repeat the process: 133 / 53

Moving on to step 3:
When dividing 133 by 53, we get 2 with a remainder of 27.
The number 2 becomes the next digit in our result. 
Result so far: 12.0
If we take 106 away from 133, we end up with 27.
Append the next digit (6) from the dividend to 27 and continue with: 276 / 53

Step 4:
The number 53 fits into 276 5 times, leaving a remainder of 11.
Put 5 as the next digit of the answer. 
Result so far: 125.0
Deduct 265 from 276 and we're left with 11.
Append the next digit (9) from the dividend to 11 and continue with: 119 / 53

Moving on to step 5:
53 goes into 119 2 times with a remainder of 13.
The number 2 becomes the next digit in our result. 
Result so far: 1252.0
If we take 106 away from 119, we end up with 13.
Fetch the next digit (1) from the dividend, attach it to 13 and continue: 131 / 53

Step 6:
131 divided by 53 is 2 with a remainder of 25.
Use 2 as the next digit of our solution. 
Result so far: 12522.0
The remainder is 25 after subtracting 106 from 131.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Going ahead to step 7:
53 can be fit into 250 4 times, resulting in a remainder of 38.
Put 4 as the next digit of the answer. 
Result so far: 12522.4
If we take 212 away from 250, we end up with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Let's proceed to step 8:
380 divided by 53 is 7 with a remainder of 9.
Write down 7 as next digit of the result. 
Result so far: 12522.47
The remainder is 9 after subtracting 371 from 380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Let's proceed to step 9:
53 can be fit into 90 1 times, resulting in a remainder of 37.
Record the quotient 1 as the next digit in the result. 
Result so far: 12522.471
The remainder is 37 after subtracting 53 from 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Let's proceed to step 10:
370 divided by 53 is 6 with a remainder of 52.
The number 6 becomes the next digit in our result. 
Result so far: 12522.4716
Subtract 318 from 370 to get 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Let's proceed to step 11:
If we divide 520 by 53, we get 9 and a remainder of 43.
Write down 9 as next digit of the result. 
Result so far: 12522.47169
The remainder is 43 after subtracting 477 from 520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Going ahead to step 12:
53 goes into 430 8 times with a remainder of 6.
Write down 8 as next digit of the result. 
Result so far: 12522.471698
The remainder is 6 after subtracting 424 from 430.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Advancing to step 13:
53 can be fit into 60 1 times, resulting in a remainder of 7.
Use 1 as the next digit of our solution. 
Result so far: 12522.4716981
Subtract 53 from 60 to get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Going ahead to step 14:
The number 53 fits into 70 1 times, leaving a remainder of 17.
Record the quotient 1 as the next digit in the result. 
Result so far: 12522.47169811
The remainder is 17 after subtracting 53 from 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Our division results in 12522.47169811 with a remaining 1.7e-08.
