76680251 ÷ 45 
We're looking to find how many times 45 goes into 76680251.

Moving on to step 1:
7 divided by 45 is 0 with a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Append the next digit (6) from the dividend to 7 and continue with: 76 / 45

Moving on to step 2:
If we divide 76 by 45, we get 1 and a remainder of 31.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
The remainder is 31 after subtracting 45 from 76.
Take the next digit (6) from the dividend and append it to 31, then repeat: 316 / 45

Going ahead to step 3:
When dividing 316 by 45, we get 7 with a remainder of 1.
Put 7 as the next digit of the answer. 
Result so far: 17.0
Subtract 315 from 316 to get 1.
Fetch the next digit (8) from the dividend, attach it to 1 and continue: 18 / 45

Going ahead to step 4:
If we divide 18 by 45, we get 0 and a remainder of 18.
Record the quotient 0 as the next digit in the result. 
Result so far: 170.0
If we subtract 0 from 18, we get 18.
Include the next digit (0) from the dividend after 18, then repeat: 180 / 45

Step 5:
If we divide 180 by 45, we get 4 and a remainder of 0.
The next digit of our result is 4. 
Result so far: 1704.0
The remainder is 0 after subtracting 180 from 180.
Fetch the next digit (2) from the dividend, attach it to 0 and continue: 2 / 45

Moving on to step 6:
45 goes into 2 0 times with a remainder of 2.
The next digit of our result is 0. 
Result so far: 17040.0
Deduct 0 from 2 and we're left with 2.
Append the next digit (5) from the dividend to 2 and continue with: 25 / 45

Advancing to step 7:
If we divide 25 by 45, we get 0 and a remainder of 25.
Record the quotient 0 as the next digit in the result. 
Result so far: 170400.0
Subtract 0 from 25 to get 25.
Grab the next digit (1) from the dividend, add it to 25, then carry on: 251 / 45

Let's proceed to step 8:
45 goes into 251 5 times with a remainder of 26.
Put 5 as the next digit of the answer. 
Result so far: 1704005.0
If we subtract 225 from 251, we get 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Step 9:
If we divide 260 by 45, we get 5 and a remainder of 35.
The number 5 becomes the next digit in our result. 
Result so far: 1704005.5
The remainder is 35 after subtracting 225 from 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Let's proceed to step 10:
The number 45 fits into 350 7 times, leaving a remainder of 35.
Record the quotient 7 as the next digit in the result. 
Result so far: 1704005.57
If we subtract 315 from 350, we get 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Step 11:
The number 45 fits into 350 7 times, leaving a remainder of 35.
The next digit of our result is 7. 
Result so far: 1704005.577
Deduct 315 from 350 and we're left with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

The final outcome is 1704005.577, with a leftover of 0.0035.
