We're dividing 78745625 by 661 
We want to figure out the number of times 78745625 can be divided by 661.

Step 1:
661 goes into 7 0 times 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.
Bring next digit (8) of the dividend behind the 7 and repeat the process: 78 / 661

Advancing to step 2:
If we divide 78 by 661, we get 0 and 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 (7) from the dividend, add it to 78, then carry on: 787 / 661

Let's proceed to step 3:
The number 661 fits into 787 1 times, leaving a remainder of 126.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we subtract 661 from 787, we get 126.
Include the next digit (4) from the dividend after 126, then repeat: 1264 / 661

Advancing to step 4:
The number 661 fits into 1264 1 times, leaving a remainder of 603.
The next digit of our result is 1. 
Result so far: 11.0
The remainder is 603 after subtracting 661 from 1264.
Grab the next digit (5) from the dividend, add it to 603, then carry on: 6035 / 661

Going ahead to step 5:
If we divide 6035 by 661, we get 9 and a remainder of 86.
Put 9 as the next digit of the answer. 
Result so far: 119.0
Deduct 5949 from 6035 and we're left with 86.
Append the next digit (6) from the dividend to 86 and continue with: 866 / 661

Let's proceed to step 6:
If we divide 866 by 661, we get 1 and a remainder of 205.
The next digit of our result is 1. 
Result so far: 1191.0
Deduct 661 from 866 and we're left with 205.
Grab the next digit (2) from the dividend, add it to 205, then carry on: 2052 / 661

On to step 7:
661 can be fit into 2052 3 times, resulting in a remainder of 69.
Record the quotient 3 as the next digit in the result. 
Result so far: 11913.0
If we subtract 1983 from 2052, we get 69.
Append the next digit (5) from the dividend to 69 and continue with: 695 / 661

Advancing to step 8:
When dividing 695 by 661, we get 1 with a remainder of 34.
The next digit of our result is 1. 
Result so far: 119131.0
If we take 661 away from 695, we end up with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Moving on to step 9:
661 can be fit into 340 0 times, resulting in a remainder of 340.
Use 0 as the next digit of our solution. 
Result so far: 119131.0
If we take 0 away from 340, we end up with 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3400, and continue the process.

Advancing to step 10:
3400 divided by 661 is 5 with a remainder of 95.
The next digit of our result is 5. 
Result so far: 119131.05
If we take 3305 away from 3400, we end up with 95.
Since there are no more digits in the dividend, we add a zero to the remainder making it 950, and continue the process.

Moving on to step 11:
The number 661 fits into 950 1 times, leaving a remainder of 289.
Put 1 as the next digit of the answer. 
Result so far: 119131.051
If we take 661 away from 950, we end up with 289.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2890, and continue the process.

Advancing to step 12:
661 goes into 2890 4 times with a remainder of 246.
The next digit of our result is 4. 
Result so far: 119131.0514
Subtract 2644 from 2890 to get 246.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2460, and continue the process.

Let's proceed to step 13:
661 goes into 2460 3 times with a remainder of 477.
Record the quotient 3 as the next digit in the result. 
Result so far: 119131.05143
If we subtract 1983 from 2460, we get 477.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4770, and continue the process.

On to step 14:
661 goes into 4770 7 times with a remainder of 143.
Put 7 as the next digit of the answer. 
Result so far: 119131.051437
Deduct 4627 from 4770 and we're left with 143.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1430, and continue the process.

Step 15:
661 goes into 1430 2 times with a remainder of 108.
Use 2 as the next digit of our solution. 
Result so far: 119131.0514372
Deduct 1322 from 1430 and we're left with 108.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1080, and continue the process.

Advancing to step 16:
If we divide 1080 by 661, we get 1 and a remainder of 419.
Use 1 as the next digit of our solution. 
Result so far: 119131.05143721
Subtracting 661 from 1080 leaves us with 419.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4190, and continue the process.

In conclusion, the division gives 119131.05143721 with a balance of 4.19e-07.
