We divide 210640 by 53
We want to figure out the number of times 210640 can be divided by 53.

Step 1:
The number 53 fits into 2 0 times, leaving a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Grab the next digit (1) from the dividend, add it to 2, then carry on: 21 / 53

Going ahead to step 2:
53 can be fit into 21 0 times, resulting in a remainder of 21.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 21 to get 21.
Append the next digit (0) from the dividend to 21 and continue with: 210 / 53

Let's proceed to step 3:
When dividing 210 by 53, we get 3 with a remainder of 51.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
If we take 159 away from 210, we end up with 51.
Grab the next digit (6) from the dividend, add it to 51, then carry on: 516 / 53

Let's proceed to step 4:
If we divide 516 by 53, we get 9 and a remainder of 39.
Record the quotient 9 as the next digit in the result. 
Result so far: 39.0
The remainder is 39 after subtracting 477 from 516.
Fetch the next digit (4) from the dividend, attach it to 39 and continue: 394 / 53

Step 5:
394 divided by 53 is 7 with a remainder of 23.
Write down 7 as next digit of the result. 
Result so far: 397.0
If we subtract 371 from 394, we get 23.
Fetch the next digit (0) from the dividend, attach it to 23 and continue: 230 / 53

Going ahead to step 6:
When dividing 230 by 53, we get 4 with a remainder of 18.
Write down 4 as next digit of the result. 
Result so far: 3974.0
Deduct 212 from 230 and we're left with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Going ahead to step 7:
53 can be fit into 180 3 times, resulting in a remainder of 21.
Write down 3 as next digit of the result. 
Result so far: 3974.3
If we subtract 159 from 180, we get 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Going ahead to step 8:
53 goes into 210 3 times with a remainder of 51.
Put 3 as the next digit of the answer. 
Result so far: 3974.33
Subtract 159 from 210 to get 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

In conclusion, the division gives 3974.33 with a balance of 0.051.
