537643 ÷ 51 
We want to divide 537643 by 51.

Let's proceed to step 1:
The number 51 fits into 5 0 times, leaving a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Grab the next digit (3) from the dividend, add it to 5, then carry on: 53 / 51

Moving on to step 2:
When dividing 53 by 51, we get 1 with a remainder of 2.
The next digit of our result is 1. 
Result so far: 1.0
Deduct 51 from 53 and we're left with 2.
Grab the next digit (7) from the dividend, add it to 2, then carry on: 27 / 51

Let's proceed to step 3:
If we divide 27 by 51, we get 0 and a remainder of 27.
The number 0 becomes the next digit in our result. 
Result so far: 10.0
If we subtract 0 from 27, we get 27.
Fetch the next digit (6) from the dividend, attach it to 27 and continue: 276 / 51

Going ahead to step 4:
51 goes into 276 5 times with a remainder of 21.
The number 5 becomes the next digit in our result. 
Result so far: 105.0
Deduct 255 from 276 and we're left with 21.
Take the next digit (4) from the dividend and append it to 21, then repeat: 214 / 51

Step 5:
If we divide 214 by 51, we get 4 and a remainder of 10.
Use 4 as the next digit of our solution. 
Result so far: 1054.0
The remainder is 10 after subtracting 204 from 214.
Append the next digit (3) from the dividend to 10 and continue with: 103 / 51

Advancing to step 6:
51 can be fit into 103 2 times, resulting in a remainder of 1.
The number 2 becomes the next digit in our result. 
Result so far: 10542.0
The remainder is 1 after subtracting 102 from 103.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Moving on to step 7:
When dividing 10 by 51, we get 0 with a remainder of 10.
The next digit of our result is 0. 
Result so far: 10542.0
If we take 0 away from 10, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 8:
The number 51 fits into 100 1 times, leaving a remainder of 49.
Record the quotient 1 as the next digit in the result. 
Result so far: 10542.01
Subtract 51 from 100 to get 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Moving on to step 9:
490 divided by 51 is 9 with a remainder of 31.
The number 9 becomes the next digit in our result. 
Result so far: 10542.019
The remainder is 31 after subtracting 459 from 490.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

On to step 10:
When dividing 310 by 51, we get 6 with a remainder of 4.
The number 6 becomes the next digit in our result. 
Result so far: 10542.0196
Subtracting 306 from 310 leaves us with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Let's proceed to step 11:
40 divided by 51 is 0 with a remainder of 40.
Use 0 as the next digit of our solution. 
Result so far: 10542.0196
Subtracting 0 from 40 leaves us with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Let's proceed to step 12:
51 goes into 400 7 times with a remainder of 43.
The number 7 becomes the next digit in our result. 
Result so far: 10542.019607
Subtract 357 from 400 to get 43.
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 13:
When dividing 430 by 51, we get 8 with a remainder of 22.
Put 8 as the next digit of the answer. 
Result so far: 10542.0196078
Deduct 408 from 430 and we're left with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Let's proceed to step 14:
51 goes into 220 4 times with a remainder of 16.
Record the quotient 4 as the next digit in the result. 
Result so far: 10542.01960784
Subtract 204 from 220 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

The final outcome is 10542.01960784, with a leftover of 1.6e-08.
