4139085 ÷ 802 
We want to figure out the number of times 4139085 can be divided by 802.

Step 1:
4 divided by 802 is 0 with a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Take the next digit (1) from the dividend and append it to 4, then repeat: 41 / 802

Moving on to step 2:
41 divided by 802 is 0 with a remainder of 41.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 41 and we're left with 41.
Grab the next digit (3) from the dividend, add it to 41, then carry on: 413 / 802

Advancing to step 3:
413 divided by 802 is 0 with a remainder of 413.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 413 leaves us with 413.
Fetch the next digit (9) from the dividend, attach it to 413 and continue: 4139 / 802

Going ahead to step 4:
If we divide 4139 by 802, we get 5 and a remainder of 129.
Record the quotient 5 as the next digit in the result. 
Result so far: 5.0
Subtracting 4010 from 4139 leaves us with 129.
Grab the next digit (0) from the dividend, add it to 129, then carry on: 1290 / 802

Moving on to step 5:
The number 802 fits into 1290 1 times, leaving a remainder of 488.
The number 1 becomes the next digit in our result. 
Result so far: 51.0
If we take 802 away from 1290, we end up with 488.
Include the next digit (8) from the dividend after 488, then repeat: 4888 / 802

Let's proceed to step 6:
When dividing 4888 by 802, we get 6 with a remainder of 76.
The number 6 becomes the next digit in our result. 
Result so far: 516.0
If we subtract 4812 from 4888, we get 76.
Fetch the next digit (5) from the dividend, attach it to 76 and continue: 765 / 802

Going ahead to step 7:
765 divided by 802 is 0 with a remainder of 765.
Put 0 as the next digit of the answer. 
Result so far: 5160.0
If we take 0 away from 765, we end up with 765.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7650, and continue the process.

Moving on to step 8:
7650 divided by 802 is 9 with a remainder of 432.
Use 9 as the next digit of our solution. 
Result so far: 5160.9
If we take 7218 away from 7650, we end up with 432.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4320, and continue the process.

On to step 9:
802 goes into 4320 5 times with a remainder of 310.
The next digit of our result is 5. 
Result so far: 5160.95
If we subtract 4010 from 4320, we get 310.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3100, and continue the process.

Moving on to step 10:
The number 802 fits into 3100 3 times, leaving a remainder of 694.
Use 3 as the next digit of our solution. 
Result so far: 5160.953
Subtracting 2406 from 3100 leaves us with 694.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6940, and continue the process.

On to step 11:
The number 802 fits into 6940 8 times, leaving a remainder of 524.
Write down 8 as next digit of the result. 
Result so far: 5160.9538
Subtract 6416 from 6940 to get 524.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5240, and continue the process.

Step 12:
When dividing 5240 by 802, we get 6 with a remainder of 428.
Record the quotient 6 as the next digit in the result. 
Result so far: 5160.95386
Deduct 4812 from 5240 and we're left with 428.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4280, and continue the process.

Moving on to step 13:
When dividing 4280 by 802, we get 5 with a remainder of 270.
Put 5 as the next digit of the answer. 
Result so far: 5160.953865
If we subtract 4010 from 4280, we get 270.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2700, and continue the process.

Step 14:
802 can be fit into 2700 3 times, resulting in a remainder of 294.
The number 3 becomes the next digit in our result. 
Result so far: 5160.9538653
If we take 2406 away from 2700, we end up with 294.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2940, and continue the process.

On to step 15:
802 goes into 2940 3 times with a remainder of 534.
The number 3 becomes the next digit in our result. 
Result so far: 5160.95386533
Deduct 2406 from 2940 and we're left with 534.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5340, and continue the process.

In conclusion, the division gives 5160.95386533 with a balance of 5.34e-07.
