We're dividing 66835858 by 721 
We want to figure out the number of times 66835858 can be divided by 721.

Moving on to step 1:
721 goes into 6 0 times with a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Grab the next digit (6) from the dividend, add it to 6, then carry on: 66 / 721

Step 2:
The number 721 fits into 66 0 times, leaving a remainder of 66.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 66, we get 66.
Fetch the next digit (8) from the dividend, attach it to 66 and continue: 668 / 721

Step 3:
721 can be fit into 668 0 times, resulting in a remainder of 668.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 668, we end up with 668.
Append the next digit (3) from the dividend to 668 and continue with: 6683 / 721

Advancing to step 4:
The number 721 fits into 6683 9 times, leaving a remainder of 194.
Put 9 as the next digit of the answer. 
Result so far: 9.0
The remainder is 194 after subtracting 6489 from 6683.
Bring next digit (5) of the dividend behind the 194 and repeat the process: 1945 / 721

Step 5:
1945 divided by 721 is 2 with a remainder of 503.
The next digit of our result is 2. 
Result so far: 92.0
The remainder is 503 after subtracting 1442 from 1945.
Fetch the next digit (8) from the dividend, attach it to 503 and continue: 5038 / 721

Advancing to step 6:
The number 721 fits into 5038 6 times, leaving a remainder of 712.
The next digit of our result is 6. 
Result so far: 926.0
Deduct 4326 from 5038 and we're left with 712.
Bring next digit (5) of the dividend behind the 712 and repeat the process: 7125 / 721

On to step 7:
The number 721 fits into 7125 9 times, leaving a remainder of 636.
Use 9 as the next digit of our solution. 
Result so far: 9269.0
Deduct 6489 from 7125 and we're left with 636.
Bring next digit (8) of the dividend behind the 636 and repeat the process: 6368 / 721

Advancing to step 8:
If we divide 6368 by 721, we get 8 and a remainder of 600.
Put 8 as the next digit of the answer. 
Result so far: 92698.0
Subtract 5768 from 6368 to get 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6000, and continue the process.

Moving on to step 9:
If we divide 6000 by 721, we get 8 and a remainder of 232.
The number 8 becomes the next digit in our result. 
Result so far: 92698.8
If we subtract 5768 from 6000, we get 232.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2320, and continue the process.

Step 10:
721 goes into 2320 3 times with a remainder of 157.
Record the quotient 3 as the next digit in the result. 
Result so far: 92698.83
The remainder is 157 after subtracting 2163 from 2320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1570, and continue the process.

Advancing to step 11:
The number 721 fits into 1570 2 times, leaving a remainder of 128.
Write down 2 as next digit of the result. 
Result so far: 92698.832
The remainder is 128 after subtracting 1442 from 1570.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1280, and continue the process.

Advancing to step 12:
The number 721 fits into 1280 1 times, leaving a remainder of 559.
The number 1 becomes the next digit in our result. 
Result so far: 92698.8321
If we take 721 away from 1280, we end up with 559.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5590, and continue the process.

Advancing to step 13:
721 can be fit into 5590 7 times, resulting in a remainder of 543.
Record the quotient 7 as the next digit in the result. 
Result so far: 92698.83217
If we subtract 5047 from 5590, we get 543.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5430, and continue the process.

Moving on to step 14:
721 goes into 5430 7 times with a remainder of 383.
Put 7 as the next digit of the answer. 
Result so far: 92698.832177
The remainder is 383 after subtracting 5047 from 5430.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3830, and continue the process.

Our division results in 92698.832177 with a remaining 3.83e-05.
