55336187 ÷ 645 
Let's see how many times 645 fits into 55336187.

Advancing to step 1:
645 can be fit into 5 0 times, resulting in a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Bring next digit (5) of the dividend behind the 5 and repeat the process: 55 / 645

Step 2:
645 goes into 55 0 times with a remainder of 55.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 55 and we're left with 55.
Append the next digit (3) from the dividend to 55 and continue with: 553 / 645

Going ahead to step 3:
553 divided by 645 is 0 with a remainder of 553.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 553, we get 553.
Bring next digit (3) of the dividend behind the 553 and repeat the process: 5533 / 645

Going ahead to step 4:
5533 divided by 645 is 8 with a remainder of 373.
Use 8 as the next digit of our solution. 
Result so far: 8.0
Deduct 5160 from 5533 and we're left with 373.
Grab the next digit (6) from the dividend, add it to 373, then carry on: 3736 / 645

Advancing to step 5:
645 can be fit into 3736 5 times, resulting in a remainder of 511.
Record the quotient 5 as the next digit in the result. 
Result so far: 85.0
If we take 3225 away from 3736, we end up with 511.
Append the next digit (1) from the dividend to 511 and continue with: 5111 / 645

Going ahead to step 6:
645 can be fit into 5111 7 times, resulting in a remainder of 596.
The next digit of our result is 7. 
Result so far: 857.0
Subtracting 4515 from 5111 leaves us with 596.
Append the next digit (8) from the dividend to 596 and continue with: 5968 / 645

Going ahead to step 7:
When dividing 5968 by 645, we get 9 with a remainder of 163.
The next digit of our result is 9. 
Result so far: 8579.0
If we subtract 5805 from 5968, we get 163.
Fetch the next digit (7) from the dividend, attach it to 163 and continue: 1637 / 645

Step 8:
If we divide 1637 by 645, we get 2 and a remainder of 347.
Use 2 as the next digit of our solution. 
Result so far: 85792.0
Deduct 1290 from 1637 and we're left with 347.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3470, and continue the process.

Let's proceed to step 9:
If we divide 3470 by 645, we get 5 and a remainder of 245.
Write down 5 as next digit of the result. 
Result so far: 85792.5
Subtract 3225 from 3470 to get 245.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2450, and continue the process.

Going ahead to step 10:
645 goes into 2450 3 times with a remainder of 515.
The number 3 becomes the next digit in our result. 
Result so far: 85792.53
If we take 1935 away from 2450, we end up with 515.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5150, and continue the process.

Step 11:
5150 divided by 645 is 7 with a remainder of 635.
Use 7 as the next digit of our solution. 
Result so far: 85792.537
The remainder is 635 after subtracting 4515 from 5150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6350, and continue the process.

Advancing to step 12:
The number 645 fits into 6350 9 times, leaving a remainder of 545.
Write down 9 as next digit of the result. 
Result so far: 85792.5379
Deduct 5805 from 6350 and we're left with 545.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5450, and continue the process.

Step 13:
The number 645 fits into 5450 8 times, leaving a remainder of 290.
The next digit of our result is 8. 
Result so far: 85792.53798
Subtracting 5160 from 5450 leaves us with 290.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2900, and continue the process.

Let's proceed to step 14:
2900 divided by 645 is 4 with a remainder of 320.
Record the quotient 4 as the next digit in the result. 
Result so far: 85792.537984
Deduct 2580 from 2900 and we're left with 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

Going ahead to step 15:
645 can be fit into 3200 4 times, resulting in a remainder of 620.
The next digit of our result is 4. 
Result so far: 85792.5379844
If we subtract 2580 from 3200, we get 620.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6200, and continue the process.

In conclusion, the division gives 85792.5379844 with a balance of 6.2e-06.
