We're dividing 72507151 by 802 
We want to figure out the number of times 72507151 can be divided by 802.

Step 1:
802 goes into 7 0 times with a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Fetch the next digit (2) from the dividend, attach it to 7 and continue: 72 / 802

Going ahead to step 2:
72 divided by 802 is 0 with a remainder of 72.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 72, we get 72.
Include the next digit (5) from the dividend after 72, then repeat: 725 / 802

Going ahead to step 3:
When dividing 725 by 802, we get 0 with a remainder of 725.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 725, we end up with 725.
Include the next digit (0) from the dividend after 725, then repeat: 7250 / 802

Advancing to step 4:
802 can be fit into 7250 9 times, resulting in a remainder of 32.
The next digit of our result is 9. 
Result so far: 9.0
If we subtract 7218 from 7250, we get 32.
Append the next digit (7) from the dividend to 32 and continue with: 327 / 802

Moving on to step 5:
802 goes into 327 0 times with a remainder of 327.
Put 0 as the next digit of the answer. 
Result so far: 90.0
If we subtract 0 from 327, we get 327.
Append the next digit (1) from the dividend to 327 and continue with: 3271 / 802

Step 6:
3271 divided by 802 is 4 with a remainder of 63.
Use 4 as the next digit of our solution. 
Result so far: 904.0
If we subtract 3208 from 3271, we get 63.
Append the next digit (5) from the dividend to 63 and continue with: 635 / 802

Moving on to step 7:
635 divided by 802 is 0 with a remainder of 635.
Record the quotient 0 as the next digit in the result. 
Result so far: 9040.0
Deduct 0 from 635 and we're left with 635.
Grab the next digit (1) from the dividend, add it to 635, then carry on: 6351 / 802

Step 8:
6351 divided by 802 is 7 with a remainder of 737.
The number 7 becomes the next digit in our result. 
Result so far: 90407.0
Subtracting 5614 from 6351 leaves us with 737.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7370, and continue the process.

Step 9:
802 can be fit into 7370 9 times, resulting in a remainder of 152.
The number 9 becomes the next digit in our result. 
Result so far: 90407.9
Subtracting 7218 from 7370 leaves us with 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 10:
If we divide 1520 by 802, we get 1 and a remainder of 718.
Record the quotient 1 as the next digit in the result. 
Result so far: 90407.91
Subtract 802 from 1520 to get 718.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7180, and continue the process.

Step 11:
The number 802 fits into 7180 8 times, leaving a remainder of 764.
Record the quotient 8 as the next digit in the result. 
Result so far: 90407.918
If we subtract 6416 from 7180, we get 764.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7640, and continue the process.

Moving on to step 12:
The number 802 fits into 7640 9 times, leaving a remainder of 422.
The number 9 becomes the next digit in our result. 
Result so far: 90407.9189
Subtracting 7218 from 7640 leaves us with 422.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4220, and continue the process.

On to step 13:
4220 divided by 802 is 5 with a remainder of 210.
Put 5 as the next digit of the answer. 
Result so far: 90407.91895
The remainder is 210 after subtracting 4010 from 4220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2100, and continue the process.

Moving on to step 14:
The number 802 fits into 2100 2 times, leaving a remainder of 496.
Put 2 as the next digit of the answer. 
Result so far: 90407.918952
Subtract 1604 from 2100 to get 496.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4960, and continue the process.

On to step 15:
802 can be fit into 4960 6 times, resulting in a remainder of 148.
The number 6 becomes the next digit in our result. 
Result so far: 90407.9189526
Subtract 4812 from 4960 to get 148.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1480, and continue the process.

Step 16:
If we divide 1480 by 802, we get 1 and a remainder of 678.
Put 1 as the next digit of the answer. 
Result so far: 90407.91895261
Deduct 802 from 1480 and we're left with 678.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6780, and continue the process.

Our division results in 90407.91895261 with a remaining 6.78e-07.
