75138069 divided by 800 
We want to figure out the number of times 75138069 can be divided by 800.

Moving on to step 1:
If we divide 7 by 800, we get 0 and a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Grab the next digit (5) from the dividend, add it to 7, then carry on: 75 / 800

Step 2:
If we divide 75 by 800, we get 0 and a remainder of 75.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 75 after subtracting 0 from 75.
Include the next digit (1) from the dividend after 75, then repeat: 751 / 800

Let's proceed to step 3:
751 divided by 800 is 0 with a remainder of 751.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 751 to get 751.
Grab the next digit (3) from the dividend, add it to 751, then carry on: 7513 / 800

Moving on to step 4:
If we divide 7513 by 800, we get 9 and a remainder of 313.
Record the quotient 9 as the next digit in the result. 
Result so far: 9.0
If we subtract 7200 from 7513, we get 313.
Append the next digit (8) from the dividend to 313 and continue with: 3138 / 800

Step 5:
3138 divided by 800 is 3 with a remainder of 738.
Use 3 as the next digit of our solution. 
Result so far: 93.0
If we subtract 2400 from 3138, we get 738.
Append the next digit (0) from the dividend to 738 and continue with: 7380 / 800

Let's proceed to step 6:
When dividing 7380 by 800, we get 9 with a remainder of 180.
The next digit of our result is 9. 
Result so far: 939.0
Deduct 7200 from 7380 and we're left with 180.
Grab the next digit (6) from the dividend, add it to 180, then carry on: 1806 / 800

Moving on to step 7:
1806 divided by 800 is 2 with a remainder of 206.
Write down 2 as next digit of the result. 
Result so far: 9392.0
Deduct 1600 from 1806 and we're left with 206.
Fetch the next digit (9) from the dividend, attach it to 206 and continue: 2069 / 800

Step 8:
2069 divided by 800 is 2 with a remainder of 469.
Write down 2 as next digit of the result. 
Result so far: 93922.0
Subtract 1600 from 2069 to get 469.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4690, and continue the process.

Going ahead to step 9:
If we divide 4690 by 800, we get 5 and a remainder of 690.
Record the quotient 5 as the next digit in the result. 
Result so far: 93922.5
Subtract 4000 from 4690 to get 690.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6900, and continue the process.

Step 10:
800 can be fit into 6900 8 times, resulting in a remainder of 500.
The next digit of our result is 8. 
Result so far: 93922.58
Subtract 6400 from 6900 to get 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5000, and continue the process.

Moving on to step 11:
800 can be fit into 5000 6 times, resulting in a remainder of 200.
The number 6 becomes the next digit in our result. 
Result so far: 93922.586
If we subtract 4800 from 5000, we get 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

On to step 12:
800 goes into 2000 2 times with a remainder of 400.
Put 2 as the next digit of the answer. 
Result so far: 93922.5862
Deduct 1600 from 2000 and we're left with 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

Going ahead to step 13:
When dividing 4000 by 800, we get 5 with a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 93922.58625
Subtract 4000 from 4000 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 14:
If we divide 0 by 800, we get 0 and a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 93922.58625
Deduct 0 from 0 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 15:
800 can be fit into 0 0 times, resulting in a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 93922.58625
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The quotient of the division is 93922.58625, and the remainder is 0.0.
