Let's divide 48421234 by 721
Our goal is to divide 48421234 by 721.

Advancing to step 1:
4 divided by 721 is 0 with a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Grab the next digit (8) from the dividend, add it to 4, then carry on: 48 / 721

Moving on to step 2:
721 can be fit into 48 0 times, resulting in a remainder of 48.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 48 and we're left with 48.
Grab the next digit (4) from the dividend, add it to 48, then carry on: 484 / 721

Advancing to step 3:
484 divided by 721 is 0 with a remainder of 484.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 484 after subtracting 0 from 484.
Append the next digit (2) from the dividend to 484 and continue with: 4842 / 721

Advancing to step 4:
4842 divided by 721 is 6 with a remainder of 516.
Use 6 as the next digit of our solution. 
Result so far: 6.0
If we subtract 4326 from 4842, we get 516.
Bring next digit (1) of the dividend behind the 516 and repeat the process: 5161 / 721

Going ahead to step 5:
The number 721 fits into 5161 7 times, leaving a remainder of 114.
Record the quotient 7 as the next digit in the result. 
Result so far: 67.0
The remainder is 114 after subtracting 5047 from 5161.
Take the next digit (2) from the dividend and append it to 114, then repeat: 1142 / 721

Advancing to step 6:
1142 divided by 721 is 1 with a remainder of 421.
Use 1 as the next digit of our solution. 
Result so far: 671.0
If we subtract 721 from 1142, we get 421.
Bring next digit (3) of the dividend behind the 421 and repeat the process: 4213 / 721

Going ahead to step 7:
The number 721 fits into 4213 5 times, leaving a remainder of 608.
The number 5 becomes the next digit in our result. 
Result so far: 6715.0
If we subtract 3605 from 4213, we get 608.
Bring next digit (4) of the dividend behind the 608 and repeat the process: 6084 / 721

Step 8:
721 can be fit into 6084 8 times, resulting in a remainder of 316.
Use 8 as the next digit of our solution. 
Result so far: 67158.0
Subtracting 5768 from 6084 leaves us with 316.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3160, and continue the process.

Advancing to step 9:
3160 divided by 721 is 4 with a remainder of 276.
Record the quotient 4 as the next digit in the result. 
Result so far: 67158.4
If we subtract 2884 from 3160, we get 276.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2760, and continue the process.

Step 10:
The number 721 fits into 2760 3 times, leaving a remainder of 597.
The next digit of our result is 3. 
Result so far: 67158.43
Subtracting 2163 from 2760 leaves us with 597.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5970, and continue the process.

On to step 11:
721 goes into 5970 8 times with a remainder of 202.
Use 8 as the next digit of our solution. 
Result so far: 67158.438
Deduct 5768 from 5970 and we're left with 202.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2020, and continue the process.

Let's proceed to step 12:
721 goes into 2020 2 times with a remainder of 578.
Use 2 as the next digit of our solution. 
Result so far: 67158.4382
Deduct 1442 from 2020 and we're left with 578.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5780, and continue the process.

Advancing to step 13:
If we divide 5780 by 721, we get 8 and a remainder of 12.
Write down 8 as next digit of the result. 
Result so far: 67158.43828
If we take 5768 away from 5780, we end up with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Advancing to step 14:
When dividing 120 by 721, we get 0 with a remainder of 120.
The next digit of our result is 0. 
Result so far: 67158.43828
Subtracting 0 from 120 leaves us with 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Advancing to step 15:
721 can be fit into 1200 1 times, resulting in a remainder of 479.
Write down 1 as next digit of the result. 
Result so far: 67158.4382801
Deduct 721 from 1200 and we're left with 479.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4790, and continue the process.

Moving on to step 16:
If we divide 4790 by 721, we get 6 and a remainder of 464.
Put 6 as the next digit of the answer. 
Result so far: 67158.43828016
The remainder is 464 after subtracting 4326 from 4790.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4640, and continue the process.

The final outcome is 67158.43828016, with a leftover of 4.64e-07.
