45558856 ÷ 721 
Our goal is to divide 45558856 by 721.

Step 1:
721 can be fit into 4 0 times, resulting in a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Grab the next digit (5) from the dividend, add it to 4, then carry on: 45 / 721

Moving on to step 2:
If we divide 45 by 721, we get 0 and a remainder of 45.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 45 after subtracting 0 from 45.
Append the next digit (5) from the dividend to 45 and continue with: 455 / 721

Let's proceed to step 3:
721 goes into 455 0 times with a remainder of 455.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 455 to get 455.
Include the next digit (5) from the dividend after 455, then repeat: 4555 / 721

Advancing to step 4:
4555 divided by 721 is 6 with a remainder of 229.
The next digit of our result is 6. 
Result so far: 6.0
Deduct 4326 from 4555 and we're left with 229.
Bring next digit (8) of the dividend behind the 229 and repeat the process: 2298 / 721

On to step 5:
The number 721 fits into 2298 3 times, leaving a remainder of 135.
Use 3 as the next digit of our solution. 
Result so far: 63.0
Subtracting 2163 from 2298 leaves us with 135.
Append the next digit (8) from the dividend to 135 and continue with: 1358 / 721

Moving on to step 6:
When dividing 1358 by 721, we get 1 with a remainder of 637.
Put 1 as the next digit of the answer. 
Result so far: 631.0
Deduct 721 from 1358 and we're left with 637.
Include the next digit (5) from the dividend after 637, then repeat: 6375 / 721

Let's proceed to step 7:
The number 721 fits into 6375 8 times, leaving a remainder of 607.
Use 8 as the next digit of our solution. 
Result so far: 6318.0
Subtract 5768 from 6375 to get 607.
Take the next digit (6) from the dividend and append it to 607, then repeat: 6076 / 721

Advancing to step 8:
721 can be fit into 6076 8 times, resulting in a remainder of 308.
Record the quotient 8 as the next digit in the result. 
Result so far: 63188.0
Subtracting 5768 from 6076 leaves us with 308.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3080, and continue the process.

Step 9:
The number 721 fits into 3080 4 times, leaving a remainder of 196.
Write down 4 as next digit of the result. 
Result so far: 63188.4
If we subtract 2884 from 3080, we get 196.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1960, and continue the process.

Let's proceed to step 10:
721 can be fit into 1960 2 times, resulting in a remainder of 518.
Use 2 as the next digit of our solution. 
Result so far: 63188.42
If we take 1442 away from 1960, we end up with 518.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5180, and continue the process.

Moving on to step 11:
5180 divided by 721 is 7 with a remainder of 133.
Put 7 as the next digit of the answer. 
Result so far: 63188.427
The remainder is 133 after subtracting 5047 from 5180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1330, and continue the process.

Advancing to step 12:
721 goes into 1330 1 times with a remainder of 609.
Use 1 as the next digit of our solution. 
Result so far: 63188.4271
Deduct 721 from 1330 and we're left with 609.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6090, and continue the process.

Let's proceed to step 13:
721 can be fit into 6090 8 times, resulting in a remainder of 322.
Record the quotient 8 as the next digit in the result. 
Result so far: 63188.42718
Subtract 5768 from 6090 to get 322.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3220, and continue the process.

Step 14:
The number 721 fits into 3220 4 times, leaving a remainder of 336.
The number 4 becomes the next digit in our result. 
Result so far: 63188.427184
If we subtract 2884 from 3220, we get 336.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3360, and continue the process.

On to step 15:
721 can be fit into 3360 4 times, resulting in a remainder of 476.
Write down 4 as next digit of the result. 
Result so far: 63188.4271844
If we take 2884 away from 3360, we end up with 476.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4760, and continue the process.

The quotient of the division is 63188.4271844, and the remainder is 4.76e-06.
