We're dividing 76210235 by 661 
Our goal is to divide 76210235 by 661.

Step 1:
If we divide 7 by 661, 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.
Include the next digit (6) from the dividend after 7, then repeat: 76 / 661

Moving on to step 2:
76 divided by 661 is 0 with a remainder of 76.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 76, we get 76.
Grab the next digit (2) from the dividend, add it to 76, then carry on: 762 / 661

Going ahead to step 3:
If we divide 762 by 661, we get 1 and a remainder of 101.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Deduct 661 from 762 and we're left with 101.
Grab the next digit (1) from the dividend, add it to 101, then carry on: 1011 / 661

Moving on to step 4:
661 goes into 1011 1 times with a remainder of 350.
Write down 1 as next digit of the result. 
Result so far: 11.0
If we subtract 661 from 1011, we get 350.
Append the next digit (0) from the dividend to 350 and continue with: 3500 / 661

Advancing to step 5:
661 goes into 3500 5 times with a remainder of 195.
Record the quotient 5 as the next digit in the result. 
Result so far: 115.0
If we subtract 3305 from 3500, we get 195.
Append the next digit (2) from the dividend to 195 and continue with: 1952 / 661

Step 6:
When dividing 1952 by 661, we get 2 with a remainder of 630.
The next digit of our result is 2. 
Result so far: 1152.0
Subtracting 1322 from 1952 leaves us with 630.
Take the next digit (3) from the dividend and append it to 630, then repeat: 6303 / 661

On to step 7:
6303 divided by 661 is 9 with a remainder of 354.
The next digit of our result is 9. 
Result so far: 11529.0
Deduct 5949 from 6303 and we're left with 354.
Fetch the next digit (5) from the dividend, attach it to 354 and continue: 3545 / 661

Moving on to step 8:
The number 661 fits into 3545 5 times, leaving a remainder of 240.
Record the quotient 5 as the next digit in the result. 
Result so far: 115295.0
Subtract 3305 from 3545 to get 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

Advancing to step 9:
2400 divided by 661 is 3 with a remainder of 417.
Write down 3 as next digit of the result. 
Result so far: 115295.3
Deduct 1983 from 2400 and we're left with 417.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4170, and continue the process.

Step 10:
If we divide 4170 by 661, we get 6 and a remainder of 204.
Write down 6 as next digit of the result. 
Result so far: 115295.36
The remainder is 204 after subtracting 3966 from 4170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2040, and continue the process.

On to step 11:
661 can be fit into 2040 3 times, resulting in a remainder of 57.
Use 3 as the next digit of our solution. 
Result so far: 115295.363
The remainder is 57 after subtracting 1983 from 2040.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

Step 12:
When dividing 570 by 661, we get 0 with a remainder of 570.
Put 0 as the next digit of the answer. 
Result so far: 115295.363
Subtract 0 from 570 to get 570.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5700, and continue the process.

Advancing to step 13:
If we divide 5700 by 661, we get 8 and a remainder of 412.
The number 8 becomes the next digit in our result. 
Result so far: 115295.36308
Deduct 5288 from 5700 and we're left with 412.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4120, and continue the process.

On to step 14:
4120 divided by 661 is 6 with a remainder of 154.
Put 6 as the next digit of the answer. 
Result so far: 115295.363086
Subtracting 3966 from 4120 leaves us with 154.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1540, and continue the process.

Step 15:
1540 divided by 661 is 2 with a remainder of 218.
Write down 2 as next digit of the result. 
Result so far: 115295.3630862
The remainder is 218 after subtracting 1322 from 1540.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2180, and continue the process.

Advancing to step 16:
661 can be fit into 2180 3 times, resulting in a remainder of 197.
The next digit of our result is 3. 
Result so far: 115295.36308623
If we take 1983 away from 2180, we end up with 197.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1970, and continue the process.

The quotient of the division is 115295.36308623, and the remainder is 1.97e-07.
