We look at the division of 53397719 by 424 
We want to divide 53397719 by 424.

On to step 1:
If we divide 5 by 424, we get 0 and a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Append the next digit (3) from the dividend to 5 and continue with: 53 / 424

Moving on to step 2:
If we divide 53 by 424, we get 0 and a remainder of 53.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 53, we get 53.
Take the next digit (3) from the dividend and append it to 53, then repeat: 533 / 424

Advancing to step 3:
533 divided by 424 is 1 with a remainder of 109.
The next digit of our result is 1. 
Result so far: 1.0
If we subtract 424 from 533, we get 109.
Bring next digit (9) of the dividend behind the 109 and repeat the process: 1099 / 424

Let's proceed to step 4:
The number 424 fits into 1099 2 times, leaving a remainder of 251.
Use 2 as the next digit of our solution. 
Result so far: 12.0
If we take 848 away from 1099, we end up with 251.
Grab the next digit (7) from the dividend, add it to 251, then carry on: 2517 / 424

Let's proceed to step 5:
When dividing 2517 by 424, we get 5 with a remainder of 397.
The number 5 becomes the next digit in our result. 
Result so far: 125.0
Deduct 2120 from 2517 and we're left with 397.
Grab the next digit (7) from the dividend, add it to 397, then carry on: 3977 / 424

Let's proceed to step 6:
424 goes into 3977 9 times with a remainder of 161.
Put 9 as the next digit of the answer. 
Result so far: 1259.0
Subtracting 3816 from 3977 leaves us with 161.
Bring next digit (1) of the dividend behind the 161 and repeat the process: 1611 / 424

Let's proceed to step 7:
1611 divided by 424 is 3 with a remainder of 339.
The number 3 becomes the next digit in our result. 
Result so far: 12593.0
If we subtract 1272 from 1611, we get 339.
Bring next digit (9) of the dividend behind the 339 and repeat the process: 3399 / 424

Moving on to step 8:
When dividing 3399 by 424, we get 8 with a remainder of 7.
Write down 8 as next digit of the result. 
Result so far: 125938.0
Subtracting 3392 from 3399 leaves us with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Let's proceed to step 9:
If we divide 70 by 424, we get 0 and a remainder of 70.
Put 0 as the next digit of the answer. 
Result so far: 125938.0
Subtracting 0 from 70 leaves us with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Moving on to step 10:
424 can be fit into 700 1 times, resulting in a remainder of 276.
The next digit of our result is 1. 
Result so far: 125938.01
Deduct 424 from 700 and we're left with 276.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2760, and continue the process.

On to step 11:
If we divide 2760 by 424, we get 6 and a remainder of 216.
The number 6 becomes the next digit in our result. 
Result so far: 125938.016
The remainder is 216 after subtracting 2544 from 2760.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2160, and continue the process.

On to step 12:
The number 424 fits into 2160 5 times, leaving a remainder of 40.
Use 5 as the next digit of our solution. 
Result so far: 125938.0165
Subtracting 2120 from 2160 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.

Step 13:
When dividing 400 by 424, we get 0 with a remainder of 400.
Write down 0 as next digit of the result. 
Result so far: 125938.0165
The remainder is 400 after subtracting 0 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

On to step 14:
424 can be fit into 4000 9 times, resulting in a remainder of 184.
The next digit of our result is 9. 
Result so far: 125938.016509
The remainder is 184 after subtracting 3816 from 4000.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1840, and continue the process.

Moving on to step 15:
1840 divided by 424 is 4 with a remainder of 144.
Put 4 as the next digit of the answer. 
Result so far: 125938.0165094
Subtracting 1696 from 1840 leaves us with 144.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1440, and continue the process.

Advancing to step 16:
424 goes into 1440 3 times with a remainder of 168.
The number 3 becomes the next digit in our result. 
Result so far: 125938.01650943
If we subtract 1272 from 1440, we get 168.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1680, and continue the process.

The final outcome is 125938.01650943, with a leftover of 1.68e-07.
