We're dividing 45621521 by 649 
Our goal is to divide 45621521 by 649.

Going ahead to step 1:
If we divide 4 by 649, we get 0 and a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Grab the next digit (5) from the dividend, add it to 4, then carry on: 45 / 649

On to step 2:
The number 649 fits into 45 0 times, leaving a remainder of 45.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 45, we get 45.
Grab the next digit (6) from the dividend, add it to 45, then carry on: 456 / 649

Let's proceed to step 3:
649 can be fit into 456 0 times, resulting in a remainder of 456.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 456 leaves us with 456.
Include the next digit (2) from the dividend after 456, then repeat: 4562 / 649

Let's proceed to step 4:
649 goes into 4562 7 times with a remainder of 19.
Put 7 as the next digit of the answer. 
Result so far: 7.0
Subtract 4543 from 4562 to get 19.
Append the next digit (1) from the dividend to 19 and continue with: 191 / 649

Advancing to step 5:
649 goes into 191 0 times with a remainder of 191.
Record the quotient 0 as the next digit in the result. 
Result so far: 70.0
Deduct 0 from 191 and we're left with 191.
Include the next digit (5) from the dividend after 191, then repeat: 1915 / 649

On to step 6:
If we divide 1915 by 649, we get 2 and a remainder of 617.
Use 2 as the next digit of our solution. 
Result so far: 702.0
Subtracting 1298 from 1915 leaves us with 617.
Append the next digit (2) from the dividend to 617 and continue with: 6172 / 649

Let's proceed to step 7:
6172 divided by 649 is 9 with a remainder of 331.
Record the quotient 9 as the next digit in the result. 
Result so far: 7029.0
Deduct 5841 from 6172 and we're left with 331.
Bring next digit (1) of the dividend behind the 331 and repeat the process: 3311 / 649

Going ahead to step 8:
649 goes into 3311 5 times with a remainder of 66.
Put 5 as the next digit of the answer. 
Result so far: 70295.0
Subtracting 3245 from 3311 leaves us with 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

On to step 9:
If we divide 660 by 649, we get 1 and a remainder of 11.
Write down 1 as next digit of the result. 
Result so far: 70295.1
Deduct 649 from 660 and we're left with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Step 10:
649 goes into 110 0 times with a remainder of 110.
The next digit of our result is 0. 
Result so far: 70295.1
Subtract 0 from 110 to get 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1100, and continue the process.

Moving on to step 11:
649 can be fit into 1100 1 times, resulting in a remainder of 451.
The number 1 becomes the next digit in our result. 
Result so far: 70295.101
The remainder is 451 after subtracting 649 from 1100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4510, and continue the process.

Let's proceed to step 12:
649 goes into 4510 6 times with a remainder of 616.
The number 6 becomes the next digit in our result. 
Result so far: 70295.1016
Subtracting 3894 from 4510 leaves us with 616.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6160, and continue the process.

Let's proceed to step 13:
If we divide 6160 by 649, we get 9 and a remainder of 319.
The next digit of our result is 9. 
Result so far: 70295.10169
If we take 5841 away from 6160, we end up with 319.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3190, and continue the process.

Moving on to step 14:
649 goes into 3190 4 times with a remainder of 594.
The next digit of our result is 4. 
Result so far: 70295.101694
If we subtract 2596 from 3190, we get 594.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5940, and continue the process.

Moving on to step 15:
When dividing 5940 by 649, we get 9 with a remainder of 99.
Use 9 as the next digit of our solution. 
Result so far: 70295.1016949
Subtract 5841 from 5940 to get 99.
Since there are no more digits in the dividend, we add a zero to the remainder making it 990, and continue the process.

Advancing to step 16:
649 can be fit into 990 1 times, resulting in a remainder of 341.
Use 1 as the next digit of our solution. 
Result so far: 70295.10169491
If we take 649 away from 990, we end up with 341.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3410, and continue the process.

The final result is 70295.10169491 with a remainder of 3.41e-07.
