We're dividing 53419490 by 486 
We're looking to find how many times 486 goes into 53419490.

Step 1:
5 divided by 486 is 0 with a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Grab the next digit (3) from the dividend, add it to 5, then carry on: 53 / 486

Step 2:
53 divided by 486 is 0 with a remainder of 53.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 53, we get 53.
Take the next digit (4) from the dividend and append it to 53, then repeat: 534 / 486

On to step 3:
486 can be fit into 534 1 times, resulting in a remainder of 48.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtract 486 from 534 to get 48.
Append the next digit (1) from the dividend to 48 and continue with: 481 / 486

Going ahead to step 4:
When dividing 481 by 486, we get 0 with a remainder of 481.
Write down 0 as next digit of the result. 
Result so far: 10.0
If we take 0 away from 481, we end up with 481.
Take the next digit (9) from the dividend and append it to 481, then repeat: 4819 / 486

Let's proceed to step 5:
If we divide 4819 by 486, we get 9 and a remainder of 445.
Write down 9 as next digit of the result. 
Result so far: 109.0
Deduct 4374 from 4819 and we're left with 445.
Append the next digit (4) from the dividend to 445 and continue with: 4454 / 486

Advancing to step 6:
486 goes into 4454 9 times with a remainder of 80.
Record the quotient 9 as the next digit in the result. 
Result so far: 1099.0
The remainder is 80 after subtracting 4374 from 4454.
Grab the next digit (9) from the dividend, add it to 80, then carry on: 809 / 486

Let's proceed to step 7:
486 can be fit into 809 1 times, resulting in a remainder of 323.
The number 1 becomes the next digit in our result. 
Result so far: 10991.0
Subtract 486 from 809 to get 323.
Include the next digit (0) from the dividend after 323, then repeat: 3230 / 486

Moving on to step 8:
486 can be fit into 3230 6 times, resulting in a remainder of 314.
The number 6 becomes the next digit in our result. 
Result so far: 109916.0
Deduct 2916 from 3230 and we're left with 314.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3140, and continue the process.

Advancing to step 9:
When dividing 3140 by 486, we get 6 with a remainder of 224.
Record the quotient 6 as the next digit in the result. 
Result so far: 109916.6
The remainder is 224 after subtracting 2916 from 3140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2240, and continue the process.

On to step 10:
When dividing 2240 by 486, we get 4 with a remainder of 296.
The number 4 becomes the next digit in our result. 
Result so far: 109916.64
The remainder is 296 after subtracting 1944 from 2240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2960, and continue the process.

Going ahead to step 11:
When dividing 2960 by 486, we get 6 with a remainder of 44.
Write down 6 as next digit of the result. 
Result so far: 109916.646
If we subtract 2916 from 2960, we get 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

On to step 12:
When dividing 440 by 486, we get 0 with a remainder of 440.
Record the quotient 0 as the next digit in the result. 
Result so far: 109916.646
If we take 0 away from 440, we end up with 440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4400, and continue the process.

Step 13:
The number 486 fits into 4400 9 times, leaving a remainder of 26.
Write down 9 as next digit of the result. 
Result so far: 109916.64609
Subtracting 4374 from 4400 leaves us with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Advancing to step 14:
The number 486 fits into 260 0 times, leaving a remainder of 260.
Use 0 as the next digit of our solution. 
Result so far: 109916.64609
Subtracting 0 from 260 leaves us with 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2600, and continue the process.

Let's proceed to step 15:
The number 486 fits into 2600 5 times, leaving a remainder of 170.
Use 5 as the next digit of our solution. 
Result so far: 109916.6460905
If we subtract 2430 from 2600, we get 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1700, and continue the process.

Step 16:
486 can be fit into 1700 3 times, resulting in a remainder of 242.
The next digit of our result is 3. 
Result so far: 109916.64609053
If we take 1458 away from 1700, we end up with 242.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2420, and continue the process.

The final outcome is 109916.64609053, with a leftover of 2.42e-07.
