We divide 81880990 by 749
We want to figure out the number of times 81880990 can be divided by 749.

Moving on to step 1:
If we divide 8 by 749, we get 0 and a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Bring next digit (1) of the dividend behind the 8 and repeat the process: 81 / 749

On to step 2:
81 divided by 749 is 0 with a remainder of 81.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 81, we get 81.
Take the next digit (8) from the dividend and append it to 81, then repeat: 818 / 749

Advancing to step 3:
When dividing 818 by 749, we get 1 with a remainder of 69.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
The remainder is 69 after subtracting 749 from 818.
Bring next digit (8) of the dividend behind the 69 and repeat the process: 698 / 749

Advancing to step 4:
When dividing 698 by 749, we get 0 with a remainder of 698.
Write down 0 as next digit of the result. 
Result so far: 10.0
The remainder is 698 after subtracting 0 from 698.
Append the next digit (0) from the dividend to 698 and continue with: 6980 / 749

Moving on to step 5:
The number 749 fits into 6980 9 times, leaving a remainder of 239.
Use 9 as the next digit of our solution. 
Result so far: 109.0
The remainder is 239 after subtracting 6741 from 6980.
Append the next digit (9) from the dividend to 239 and continue with: 2399 / 749

Moving on to step 6:
2399 divided by 749 is 3 with a remainder of 152.
The number 3 becomes the next digit in our result. 
Result so far: 1093.0
The remainder is 152 after subtracting 2247 from 2399.
Take the next digit (9) from the dividend and append it to 152, then repeat: 1529 / 749

Let's proceed to step 7:
If we divide 1529 by 749, we get 2 and a remainder of 31.
The next digit of our result is 2. 
Result so far: 10932.0
If we subtract 1498 from 1529, we get 31.
Include the next digit (0) from the dividend after 31, then repeat: 310 / 749

Step 8:
749 can be fit into 310 0 times, resulting in a remainder of 310.
Use 0 as the next digit of our solution. 
Result so far: 109320.0
The remainder is 310 after subtracting 0 from 310.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3100, and continue the process.

Going ahead to step 9:
If we divide 3100 by 749, we get 4 and a remainder of 104.
Record the quotient 4 as the next digit in the result. 
Result so far: 109320.4
Deduct 2996 from 3100 and we're left with 104.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1040, and continue the process.

Moving on to step 10:
If we divide 1040 by 749, we get 1 and a remainder of 291.
Use 1 as the next digit of our solution. 
Result so far: 109320.41
The remainder is 291 after subtracting 749 from 1040.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2910, and continue the process.

Moving on to step 11:
The number 749 fits into 2910 3 times, leaving a remainder of 663.
Use 3 as the next digit of our solution. 
Result so far: 109320.413
If we subtract 2247 from 2910, we get 663.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6630, and continue the process.

Step 12:
The number 749 fits into 6630 8 times, leaving a remainder of 638.
Record the quotient 8 as the next digit in the result. 
Result so far: 109320.4138
Deduct 5992 from 6630 and we're left with 638.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6380, and continue the process.

On to step 13:
The number 749 fits into 6380 8 times, leaving a remainder of 388.
The number 8 becomes the next digit in our result. 
Result so far: 109320.41388
The remainder is 388 after subtracting 5992 from 6380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3880, and continue the process.

After the division, we end up with 109320.41388 and a remainder of 0.000388.
