Let's divide 52351099 by 639
Our goal is to divide 52351099 by 639.

Moving on to step 1:
639 goes into 5 0 times 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.
Include the next digit (2) from the dividend after 5, then repeat: 52 / 639

Let's proceed to step 2:
639 can be fit into 52 0 times, resulting in a remainder of 52.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 52, we get 52.
Fetch the next digit (3) from the dividend, attach it to 52 and continue: 523 / 639

Advancing to step 3:
If we divide 523 by 639, we get 0 and a remainder of 523.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 523 and we're left with 523.
Take the next digit (5) from the dividend and append it to 523, then repeat: 5235 / 639

Moving on to step 4:
If we divide 5235 by 639, we get 8 and a remainder of 123.
Write down 8 as next digit of the result. 
Result so far: 8.0
Deduct 5112 from 5235 and we're left with 123.
Include the next digit (1) from the dividend after 123, then repeat: 1231 / 639

Advancing to step 5:
639 goes into 1231 1 times with a remainder of 592.
Put 1 as the next digit of the answer. 
Result so far: 81.0
The remainder is 592 after subtracting 639 from 1231.
Include the next digit (0) from the dividend after 592, then repeat: 5920 / 639

Advancing to step 6:
When dividing 5920 by 639, we get 9 with a remainder of 169.
Record the quotient 9 as the next digit in the result. 
Result so far: 819.0
Deduct 5751 from 5920 and we're left with 169.
Fetch the next digit (9) from the dividend, attach it to 169 and continue: 1699 / 639

Advancing to step 7:
When dividing 1699 by 639, we get 2 with a remainder of 421.
Put 2 as the next digit of the answer. 
Result so far: 8192.0
Subtract 1278 from 1699 to get 421.
Append the next digit (9) from the dividend to 421 and continue with: 4219 / 639

Step 8:
When dividing 4219 by 639, we get 6 with a remainder of 385.
Put 6 as the next digit of the answer. 
Result so far: 81926.0
Subtract 3834 from 4219 to get 385.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3850, and continue the process.

Going ahead to step 9:
639 goes into 3850 6 times with a remainder of 16.
Record the quotient 6 as the next digit in the result. 
Result so far: 81926.6
If we subtract 3834 from 3850, we get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Step 10:
639 goes into 160 0 times with a remainder of 160.
Write down 0 as next digit of the result. 
Result so far: 81926.6
Subtracting 0 from 160 leaves us with 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Moving on to step 11:
If we divide 1600 by 639, we get 2 and a remainder of 322.
Use 2 as the next digit of our solution. 
Result so far: 81926.602
Subtracting 1278 from 1600 leaves us with 322.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3220, and continue the process.

Moving on to step 12:
639 can be fit into 3220 5 times, resulting in a remainder of 25.
Write down 5 as next digit of the result. 
Result so far: 81926.6025
Deduct 3195 from 3220 and we're left with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

On to step 13:
The number 639 fits into 250 0 times, leaving a remainder of 250.
The next digit of our result is 0. 
Result so far: 81926.6025
Subtracting 0 from 250 leaves us with 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2500, and continue the process.

Moving on to step 14:
The number 639 fits into 2500 3 times, leaving a remainder of 583.
The next digit of our result is 3. 
Result so far: 81926.602503
Deduct 1917 from 2500 and we're left with 583.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5830, and continue the process.

Going ahead to step 15:
639 goes into 5830 9 times with a remainder of 79.
Use 9 as the next digit of our solution. 
Result so far: 81926.6025039
Deduct 5751 from 5830 and we're left with 79.
Since there are no more digits in the dividend, we add a zero to the remainder making it 790, and continue the process.

Moving on to step 16:
The number 639 fits into 790 1 times, leaving a remainder of 151.
Write down 1 as next digit of the result. 
Result so far: 81926.60250391
Subtract 639 from 790 to get 151.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1510, and continue the process.

Our division results in 81926.60250391 with a remaining 1.51e-07.
