Let's divide 45487 by 51
We want to divide 45487 by 51.

On to step 1:
When dividing 4 by 51, we get 0 with a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Bring next digit (5) of the dividend behind the 4 and repeat the process: 45 / 51

Advancing to step 2:
When dividing 45 by 51, we get 0 with a remainder of 45.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 45 to get 45.
Take the next digit (4) from the dividend and append it to 45, then repeat: 454 / 51

On to step 3:
51 can be fit into 454 8 times, resulting in a remainder of 46.
The next digit of our result is 8. 
Result so far: 8.0
If we take 408 away from 454, we end up with 46.
Take the next digit (8) from the dividend and append it to 46, then repeat: 468 / 51

Moving on to step 4:
51 can be fit into 468 9 times, resulting in a remainder of 9.
The next digit of our result is 9. 
Result so far: 89.0
Deduct 459 from 468 and we're left with 9.
Append the next digit (7) from the dividend to 9 and continue with: 97 / 51

Let's proceed to step 5:
51 goes into 97 1 times with a remainder of 46.
Use 1 as the next digit of our solution. 
Result so far: 891.0
If we subtract 51 from 97, we get 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

On to step 6:
51 goes into 460 9 times with a remainder of 1.
The number 9 becomes the next digit in our result. 
Result so far: 891.9
The remainder is 1 after subtracting 459 from 460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Let's proceed to step 7:
51 can be fit into 10 0 times, resulting in a remainder of 10.
The number 0 becomes the next digit in our result. 
Result so far: 891.9
The remainder is 10 after subtracting 0 from 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 8:
51 can be fit into 100 1 times, resulting in a remainder of 49.
The next digit of our result is 1. 
Result so far: 891.901
Deduct 51 from 100 and we're left with 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Going ahead to step 9:
490 divided by 51 is 9 with a remainder of 31.
Use 9 as the next digit of our solution. 
Result so far: 891.9019
Deduct 459 from 490 and we're left with 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Going ahead to step 10:
When dividing 310 by 51, we get 6 with a remainder of 4.
Record the quotient 6 as the next digit in the result. 
Result so far: 891.90196
The remainder is 4 after subtracting 306 from 310.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Advancing to step 11:
If we divide 40 by 51, we get 0 and a remainder of 40.
The next digit of our result is 0. 
Result so far: 891.90196
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.

Advancing to step 12:
51 goes into 400 7 times with a remainder of 43.
Put 7 as the next digit of the answer. 
Result so far: 891.9019607
If we take 357 away from 400, we end up with 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Moving on to step 13:
430 divided by 51 is 8 with a remainder of 22.
Put 8 as the next digit of the answer. 
Result so far: 891.90196078
Subtracting 408 from 430 leaves us 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.

The final outcome is 891.90196078, with a leftover of 2.2e-08.
