Let's divide 45103577 by 868
Our goal is to divide 45103577 by 868.

Moving on to step 1:
If we divide 4 by 868, we get 0 and a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Take the next digit (5) from the dividend and append it to 4, then repeat: 45 / 868

Step 2:
The number 868 fits into 45 0 times, leaving a remainder of 45.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 45 after subtracting 0 from 45.
Include the next digit (1) from the dividend after 45, then repeat: 451 / 868

Advancing to step 3:
If we divide 451 by 868, we get 0 and a remainder of 451.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 451, we get 451.
Bring next digit (0) of the dividend behind the 451 and repeat the process: 4510 / 868

On to step 4:
868 goes into 4510 5 times with a remainder of 170.
The number 5 becomes the next digit in our result. 
Result so far: 5.0
The remainder is 170 after subtracting 4340 from 4510.
Take the next digit (3) from the dividend and append it to 170, then repeat: 1703 / 868

Advancing to step 5:
1703 divided by 868 is 1 with a remainder of 835.
Put 1 as the next digit of the answer. 
Result so far: 51.0
Deduct 868 from 1703 and we're left with 835.
Append the next digit (5) from the dividend to 835 and continue with: 8355 / 868

On to step 6:
When dividing 8355 by 868, we get 9 with a remainder of 543.
The next digit of our result is 9. 
Result so far: 519.0
If we subtract 7812 from 8355, we get 543.
Take the next digit (7) from the dividend and append it to 543, then repeat: 5437 / 868

Advancing to step 7:
5437 divided by 868 is 6 with a remainder of 229.
Use 6 as the next digit of our solution. 
Result so far: 5196.0
Subtract 5208 from 5437 to get 229.
Grab the next digit (7) from the dividend, add it to 229, then carry on: 2297 / 868

Let's proceed to step 8:
When dividing 2297 by 868, we get 2 with a remainder of 561.
Use 2 as the next digit of our solution. 
Result so far: 51962.0
Subtract 1736 from 2297 to get 561.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5610, and continue the process.

On to step 9:
868 goes into 5610 6 times with a remainder of 402.
The number 6 becomes the next digit in our result. 
Result so far: 51962.6
If we take 5208 away from 5610, we end up with 402.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4020, and continue the process.

Advancing to step 10:
If we divide 4020 by 868, we get 4 and a remainder of 548.
Record the quotient 4 as the next digit in the result. 
Result so far: 51962.64
Subtracting 3472 from 4020 leaves us with 548.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5480, and continue the process.

Let's proceed to step 11:
5480 divided by 868 is 6 with a remainder of 272.
The number 6 becomes the next digit in our result. 
Result so far: 51962.646
The remainder is 272 after subtracting 5208 from 5480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2720, and continue the process.

Moving on to step 12:
When dividing 2720 by 868, we get 3 with a remainder of 116.
Record the quotient 3 as the next digit in the result. 
Result so far: 51962.6463
The remainder is 116 after subtracting 2604 from 2720.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1160, and continue the process.

Step 13:
868 can be fit into 1160 1 times, resulting in a remainder of 292.
Put 1 as the next digit of the answer. 
Result so far: 51962.64631
Subtracting 868 from 1160 leaves us with 292.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2920, and continue the process.

Moving on to step 14:
If we divide 2920 by 868, we get 3 and a remainder of 316.
Write down 3 as next digit of the result. 
Result so far: 51962.646313
The remainder is 316 after subtracting 2604 from 2920.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3160, and continue the process.

On to step 15:
868 can be fit into 3160 3 times, resulting in a remainder of 556.
The number 3 becomes the next digit in our result. 
Result so far: 51962.6463133
Subtracting 2604 from 3160 leaves us with 556.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5560, and continue the process.

After the division, we end up with 51962.6463133 and a remainder of 5.56e-06.
