53172099 ÷ 601 
We want to divide 53172099 by 601.

Step 1:
When dividing 5 by 601, we get 0 with 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.
Bring next digit (3) of the dividend behind the 5 and repeat the process: 53 / 601

Moving on to step 2:
The number 601 fits into 53 0 times, leaving a remainder of 53.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 53, we get 53.
Fetch the next digit (1) from the dividend, attach it to 53 and continue: 531 / 601

Let's proceed to step 3:
531 divided by 601 is 0 with a remainder of 531.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 531 leaves us with 531.
Fetch the next digit (7) from the dividend, attach it to 531 and continue: 5317 / 601

Let's proceed to step 4:
When dividing 5317 by 601, we get 8 with a remainder of 509.
Put 8 as the next digit of the answer. 
Result so far: 8.0
The remainder is 509 after subtracting 4808 from 5317.
Bring next digit (2) of the dividend behind the 509 and repeat the process: 5092 / 601

Step 5:
5092 divided by 601 is 8 with a remainder of 284.
Put 8 as the next digit of the answer. 
Result so far: 88.0
Deduct 4808 from 5092 and we're left with 284.
Take the next digit (0) from the dividend and append it to 284, then repeat: 2840 / 601

Let's proceed to step 6:
The number 601 fits into 2840 4 times, leaving a remainder of 436.
Write down 4 as next digit of the result. 
Result so far: 884.0
If we take 2404 away from 2840, we end up with 436.
Include the next digit (9) from the dividend after 436, then repeat: 4369 / 601

Going ahead to step 7:
The number 601 fits into 4369 7 times, leaving a remainder of 162.
Write down 7 as next digit of the result. 
Result so far: 8847.0
Subtract 4207 from 4369 to get 162.
Bring next digit (9) of the dividend behind the 162 and repeat the process: 1629 / 601

Let's proceed to step 8:
When dividing 1629 by 601, we get 2 with a remainder of 427.
Record the quotient 2 as the next digit in the result. 
Result so far: 88472.0
If we take 1202 away from 1629, we end up with 427.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4270, and continue the process.

Moving on to step 9:
601 goes into 4270 7 times with a remainder of 63.
Put 7 as the next digit of the answer. 
Result so far: 88472.7
If we subtract 4207 from 4270, we get 63.
Since there are no more digits in the dividend, we add a zero to the remainder making it 630, and continue the process.

Let's proceed to step 10:
601 can be fit into 630 1 times, resulting in a remainder of 29.
Record the quotient 1 as the next digit in the result. 
Result so far: 88472.71
Subtract 601 from 630 to get 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Going ahead to step 11:
The number 601 fits into 290 0 times, leaving a remainder of 290.
Put 0 as the next digit of the answer. 
Result so far: 88472.71
The remainder is 290 after subtracting 0 from 290.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2900, and continue the process.

Going ahead to step 12:
The number 601 fits into 2900 4 times, leaving a remainder of 496.
Record the quotient 4 as the next digit in the result. 
Result so far: 88472.7104
Subtracting 2404 from 2900 leaves us with 496.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4960, and continue the process.

Step 13:
601 can be fit into 4960 8 times, resulting in a remainder of 152.
The number 8 becomes the next digit in our result. 
Result so far: 88472.71048
If we subtract 4808 from 4960, we get 152.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1520, and continue the process.

Advancing to step 14:
The number 601 fits into 1520 2 times, leaving a remainder of 318.
The number 2 becomes the next digit in our result. 
Result so far: 88472.710482
Subtracting 1202 from 1520 leaves us with 318.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3180, and continue the process.

On to step 15:
601 can be fit into 3180 5 times, resulting in a remainder of 175.
Put 5 as the next digit of the answer. 
Result so far: 88472.7104825
Deduct 3005 from 3180 and we're left with 175.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1750, and continue the process.

Moving on to step 16:
601 can be fit into 1750 2 times, resulting in a remainder of 548.
Write down 2 as next digit of the result. 
Result so far: 88472.71048252
If we take 1202 away from 1750, we end up with 548.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5480, and continue the process.

The final outcome is 88472.71048252, with a leftover of 5.48e-07.
