Let's divide 81638421 by 722
Let's see how many times 722 fits into 81638421.

Moving on to step 1:
When dividing 8 by 722, we get 0 with a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Fetch the next digit (1) from the dividend, attach it to 8 and continue: 81 / 722

Moving on to step 2:
The number 722 fits into 81 0 times, leaving a remainder of 81.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 81 and we're left with 81.
Take the next digit (6) from the dividend and append it to 81, then repeat: 816 / 722

Step 3:
If we divide 816 by 722, we get 1 and a remainder of 94.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtract 722 from 816 to get 94.
Append the next digit (3) from the dividend to 94 and continue with: 943 / 722

Step 4:
If we divide 943 by 722, we get 1 and a remainder of 221.
The number 1 becomes the next digit in our result. 
Result so far: 11.0
Subtracting 722 from 943 leaves us with 221.
Grab the next digit (8) from the dividend, add it to 221, then carry on: 2218 / 722

Going ahead to step 5:
The number 722 fits into 2218 3 times, leaving a remainder of 52.
Use 3 as the next digit of our solution. 
Result so far: 113.0
Subtract 2166 from 2218 to get 52.
Append the next digit (4) from the dividend to 52 and continue with: 524 / 722

Advancing to step 6:
If we divide 524 by 722, we get 0 and a remainder of 524.
The number 0 becomes the next digit in our result. 
Result so far: 1130.0
Subtract 0 from 524 to get 524.
Bring next digit (2) of the dividend behind the 524 and repeat the process: 5242 / 722

On to step 7:
722 goes into 5242 7 times with a remainder of 188.
The number 7 becomes the next digit in our result. 
Result so far: 11307.0
The remainder is 188 after subtracting 5054 from 5242.
Append the next digit (1) from the dividend to 188 and continue with: 1881 / 722

Going ahead to step 8:
1881 divided by 722 is 2 with a remainder of 437.
Put 2 as the next digit of the answer. 
Result so far: 113072.0
Deduct 1444 from 1881 and we're left with 437.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4370, and continue the process.

Going ahead to step 9:
When dividing 4370 by 722, we get 6 with a remainder of 38.
Write down 6 as next digit of the result. 
Result so far: 113072.6
Subtracting 4332 from 4370 leaves us with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Advancing to step 10:
380 divided by 722 is 0 with a remainder of 380.
The number 0 becomes the next digit in our result. 
Result so far: 113072.6
Deduct 0 from 380 and we're left with 380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3800, and continue the process.

Moving on to step 11:
722 can be fit into 3800 5 times, resulting in a remainder of 190.
Put 5 as the next digit of the answer. 
Result so far: 113072.605
The remainder is 190 after subtracting 3610 from 3800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1900, and continue the process.

Advancing to step 12:
When dividing 1900 by 722, we get 2 with a remainder of 456.
The next digit of our result is 2. 
Result so far: 113072.6052
Subtracting 1444 from 1900 leaves us with 456.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4560, and continue the process.

On to step 13:
The number 722 fits into 4560 6 times, leaving a remainder of 228.
The next digit of our result is 6. 
Result so far: 113072.60526
Subtract 4332 from 4560 to get 228.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2280, and continue the process.

Advancing to step 14:
The number 722 fits into 2280 3 times, leaving a remainder of 114.
The next digit of our result is 3. 
Result so far: 113072.605263
If we subtract 2166 from 2280, we get 114.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1140, and continue the process.

Advancing to step 15:
722 can be fit into 1140 1 times, resulting in a remainder of 418.
Record the quotient 1 as the next digit in the result. 
Result so far: 113072.6052631
Subtract 722 from 1140 to get 418.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4180, and continue the process.

Let's proceed to step 16:
If we divide 4180 by 722, we get 5 and a remainder of 570.
Record the quotient 5 as the next digit in the result. 
Result so far: 113072.60526315
Subtract 3610 from 4180 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.

The final outcome is 113072.60526315, with a leftover of 5.7e-07.
