55399373 ÷ 650 
Our goal is to divide 55399373 by 650.

On to step 1:
650 can be fit into 5 0 times, resulting in a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Grab the next digit (5) from the dividend, add it to 5, then carry on: 55 / 650

Advancing to step 2:
650 goes into 55 0 times with a remainder of 55.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 55 and we're left with 55.
Fetch the next digit (3) from the dividend, attach it to 55 and continue: 553 / 650

Moving on to step 3:
When dividing 553 by 650, we get 0 with a remainder of 553.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 553 and we're left with 553.
Fetch the next digit (9) from the dividend, attach it to 553 and continue: 5539 / 650

Step 4:
If we divide 5539 by 650, we get 8 and a remainder of 339.
Put 8 as the next digit of the answer. 
Result so far: 8.0
If we subtract 5200 from 5539, we get 339.
Append the next digit (9) from the dividend to 339 and continue with: 3399 / 650

Step 5:
650 goes into 3399 5 times with a remainder of 149.
Put 5 as the next digit of the answer. 
Result so far: 85.0
The remainder is 149 after subtracting 3250 from 3399.
Fetch the next digit (3) from the dividend, attach it to 149 and continue: 1493 / 650

Moving on to step 6:
When dividing 1493 by 650, we get 2 with a remainder of 193.
Put 2 as the next digit of the answer. 
Result so far: 852.0
The remainder is 193 after subtracting 1300 from 1493.
Fetch the next digit (7) from the dividend, attach it to 193 and continue: 1937 / 650

On to step 7:
650 goes into 1937 2 times with a remainder of 637.
The number 2 becomes the next digit in our result. 
Result so far: 8522.0
Subtracting 1300 from 1937 leaves us with 637.
Include the next digit (3) from the dividend after 637, then repeat: 6373 / 650

Step 8:
If we divide 6373 by 650, we get 9 and a remainder of 523.
Use 9 as the next digit of our solution. 
Result so far: 85229.0
If we subtract 5850 from 6373, we get 523.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5230, and continue the process.

Let's proceed to step 9:
5230 divided by 650 is 8 with a remainder of 30.
Write down 8 as next digit of the result. 
Result so far: 85229.8
The remainder is 30 after subtracting 5200 from 5230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Step 10:
If we divide 300 by 650, we get 0 and a remainder of 300.
Use 0 as the next digit of our solution. 
Result so far: 85229.8
Subtracting 0 from 300 leaves us with 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

Moving on to step 11:
If we divide 3000 by 650, we get 4 and a remainder of 400.
Record the quotient 4 as the next digit in the result. 
Result so far: 85229.804
If we take 2600 away from 3000, we end up with 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

Advancing to step 12:
If we divide 4000 by 650, we get 6 and a remainder of 100.
The next digit of our result is 6. 
Result so far: 85229.8046
If we take 3900 away from 4000, we end up with 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

On to step 13:
650 can be fit into 1000 1 times, resulting in a remainder of 350.
Put 1 as the next digit of the answer. 
Result so far: 85229.80461
Subtract 650 from 1000 to get 350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3500, and continue the process.

Going ahead to step 14:
The number 650 fits into 3500 5 times, leaving a remainder of 250.
Record the quotient 5 as the next digit in the result. 
Result so far: 85229.804615
Subtract 3250 from 3500 to get 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2500, and continue the process.

On to step 15:
When dividing 2500 by 650, we get 3 with a remainder of 550.
Write down 3 as next digit of the result. 
Result so far: 85229.8046153
Subtract 1950 from 2500 to get 550.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5500, and continue the process.

Going ahead to step 16:
The number 650 fits into 5500 8 times, leaving a remainder of 300.
Use 8 as the next digit of our solution. 
Result so far: 85229.80461538
Subtract 5200 from 5500 to get 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

The final result is 85229.80461538 with a remainder of 3e-07.
