We divide 78400974 by 689
We want to figure out the number of times 78400974 can be divided by 689.

Let's proceed to step 1:
The number 689 fits into 7 0 times, leaving a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Take the next digit (8) from the dividend and append it to 7, then repeat: 78 / 689

Going ahead to step 2:
When dividing 78 by 689, we get 0 with a remainder of 78.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 78 leaves us with 78.
Grab the next digit (4) from the dividend, add it to 78, then carry on: 784 / 689

Let's proceed to step 3:
689 goes into 784 1 times with a remainder of 95.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtracting 689 from 784 leaves us with 95.
Take the next digit (0) from the dividend and append it to 95, then repeat: 950 / 689

Step 4:
If we divide 950 by 689, we get 1 and a remainder of 261.
Use 1 as the next digit of our solution. 
Result so far: 11.0
Subtracting 689 from 950 leaves us with 261.
Fetch the next digit (0) from the dividend, attach it to 261 and continue: 2610 / 689

Going ahead to step 5:
689 can be fit into 2610 3 times, resulting in a remainder of 543.
The next digit of our result is 3. 
Result so far: 113.0
Deduct 2067 from 2610 and we're left with 543.
Take the next digit (9) from the dividend and append it to 543, then repeat: 5439 / 689

Step 6:
The number 689 fits into 5439 7 times, leaving a remainder of 616.
Put 7 as the next digit of the answer. 
Result so far: 1137.0
The remainder is 616 after subtracting 4823 from 5439.
Append the next digit (7) from the dividend to 616 and continue with: 6167 / 689

Moving on to step 7:
When dividing 6167 by 689, we get 8 with a remainder of 655.
The next digit of our result is 8. 
Result so far: 11378.0
Deduct 5512 from 6167 and we're left with 655.
Append the next digit (4) from the dividend to 655 and continue with: 6554 / 689

Going ahead to step 8:
689 goes into 6554 9 times with a remainder of 353.
The next digit of our result is 9. 
Result so far: 113789.0
If we subtract 6201 from 6554, we get 353.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3530, and continue the process.

Moving on to step 9:
689 can be fit into 3530 5 times, resulting in a remainder of 85.
Record the quotient 5 as the next digit in the result. 
Result so far: 113789.5
If we take 3445 away from 3530, we end up with 85.
Since there are no more digits in the dividend, we add a zero to the remainder making it 850, and continue the process.

Step 10:
The number 689 fits into 850 1 times, leaving a remainder of 161.
Put 1 as the next digit of the answer. 
Result so far: 113789.51
If we take 689 away from 850, we end up with 161.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1610, and continue the process.

Advancing to step 11:
689 goes into 1610 2 times with a remainder of 232.
The number 2 becomes the next digit in our result. 
Result so far: 113789.512
Subtracting 1378 from 1610 leaves us with 232.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2320, and continue the process.

Let's proceed to step 12:
If we divide 2320 by 689, we get 3 and a remainder of 253.
The next digit of our result is 3. 
Result so far: 113789.5123
Subtracting 2067 from 2320 leaves us with 253.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2530, and continue the process.

Moving on to step 13:
689 goes into 2530 3 times with a remainder of 463.
Record the quotient 3 as the next digit in the result. 
Result so far: 113789.51233
If we subtract 2067 from 2530, we get 463.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4630, and continue the process.

Our division results in 113789.51233 with a remaining 0.000463.
