We look at the division of 53712442 by 599 
We want to figure out the number of times 53712442 can be divided by 599.

Let's proceed to step 1:
The number 599 fits into 5 0 times, leaving a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Fetch the next digit (3) from the dividend, attach it to 5 and continue: 53 / 599

On to step 2:
The number 599 fits into 53 0 times, leaving a remainder of 53.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 53 and we're left with 53.
Include the next digit (7) from the dividend after 53, then repeat: 537 / 599

Moving on to step 3:
599 goes into 537 0 times with a remainder of 537.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 537, we end up with 537.
Include the next digit (1) from the dividend after 537, then repeat: 5371 / 599

On to step 4:
5371 divided by 599 is 8 with a remainder of 579.
Use 8 as the next digit of our solution. 
Result so far: 8.0
If we take 4792 away from 5371, we end up with 579.
Include the next digit (2) from the dividend after 579, then repeat: 5792 / 599

Advancing to step 5:
599 can be fit into 5792 9 times, resulting in a remainder of 401.
Write down 9 as next digit of the result. 
Result so far: 89.0
The remainder is 401 after subtracting 5391 from 5792.
Append the next digit (4) from the dividend to 401 and continue with: 4014 / 599

Moving on to step 6:
4014 divided by 599 is 6 with a remainder of 420.
Write down 6 as next digit of the result. 
Result so far: 896.0
The remainder is 420 after subtracting 3594 from 4014.
Take the next digit (4) from the dividend and append it to 420, then repeat: 4204 / 599

Step 7:
4204 divided by 599 is 7 with a remainder of 11.
Write down 7 as next digit of the result. 
Result so far: 8967.0
Deduct 4193 from 4204 and we're left with 11.
Fetch the next digit (2) from the dividend, attach it to 11 and continue: 112 / 599

Let's proceed to step 8:
112 divided by 599 is 0 with a remainder of 112.
Record the quotient 0 as the next digit in the result. 
Result so far: 89670.0
If we subtract 0 from 112, we get 112.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1120, and continue the process.

Step 9:
599 can be fit into 1120 1 times, resulting in a remainder of 521.
Use 1 as the next digit of our solution. 
Result so far: 89670.1
Subtracting 599 from 1120 leaves us with 521.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5210, and continue the process.

Moving on to step 10:
When dividing 5210 by 599, we get 8 with a remainder of 418.
The number 8 becomes the next digit in our result. 
Result so far: 89670.18
Subtract 4792 from 5210 to get 418.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4180, and continue the process.

Step 11:
The number 599 fits into 4180 6 times, leaving a remainder of 586.
Use 6 as the next digit of our solution. 
Result so far: 89670.186
Subtract 3594 from 4180 to get 586.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5860, and continue the process.

Going ahead to step 12:
If we divide 5860 by 599, we get 9 and a remainder of 469.
Record the quotient 9 as the next digit in the result. 
Result so far: 89670.1869
Deduct 5391 from 5860 and we're left with 469.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4690, and continue the process.

Step 13:
The number 599 fits into 4690 7 times, leaving a remainder of 497.
Record the quotient 7 as the next digit in the result. 
Result so far: 89670.18697
Subtract 4193 from 4690 to get 497.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4970, and continue the process.

On to step 14:
If we divide 4970 by 599, we get 8 and a remainder of 178.
Use 8 as the next digit of our solution. 
Result so far: 89670.186978
Subtract 4792 from 4970 to get 178.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1780, and continue the process.

Let's proceed to step 15:
The number 599 fits into 1780 2 times, leaving a remainder of 582.
Record the quotient 2 as the next digit in the result. 
Result so far: 89670.1869782
Subtracting 1198 from 1780 leaves us with 582.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5820, and continue the process.

On to step 16:
599 goes into 5820 9 times with a remainder of 429.
Put 9 as the next digit of the answer. 
Result so far: 89670.18697829
The remainder is 429 after subtracting 5391 from 5820.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4290, and continue the process.

After the division, we end up with 89670.18697829 and a remainder of 4.29e-07.
