55878347 ÷ 141 
We want to figure out the number of times 55878347 can be divided by 141.

On to step 1:
If we divide 5 by 141, we get 0 and a remainder of 5.
Write down 0 as next digit of 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 / 141

Going ahead to step 2:
The number 141 fits into 55 0 times, leaving a remainder of 55.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 55, we end up with 55.
Take the next digit (8) from the dividend and append it to 55, then repeat: 558 / 141

Step 3:
141 can be fit into 558 3 times, resulting in a remainder of 135.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
Deduct 423 from 558 and we're left with 135.
Grab the next digit (7) from the dividend, add it to 135, then carry on: 1357 / 141

Going ahead to step 4:
If we divide 1357 by 141, we get 9 and a remainder of 88.
Record the quotient 9 as the next digit in the result. 
Result so far: 39.0
If we subtract 1269 from 1357, we get 88.
Bring next digit (8) of the dividend behind the 88 and repeat the process: 888 / 141

Going ahead to step 5:
888 divided by 141 is 6 with a remainder of 42.
Put 6 as the next digit of the answer. 
Result so far: 396.0
Subtracting 846 from 888 leaves us with 42.
Grab the next digit (3) from the dividend, add it to 42, then carry on: 423 / 141

Advancing to step 6:
423 divided by 141 is 3 with a remainder of 0.
The number 3 becomes the next digit in our result. 
Result so far: 3963.0
If we subtract 423 from 423, we get 0.
Include the next digit (4) from the dividend after 0, then repeat: 4 / 141

Let's proceed to step 7:
If we divide 4 by 141, we get 0 and a remainder of 4.
The next digit of our result is 0. 
Result so far: 39630.0
If we subtract 0 from 4, we get 4.
Fetch the next digit (7) from the dividend, attach it to 4 and continue: 47 / 141

Let's proceed to step 8:
47 divided by 141 is 0 with a remainder of 47.
Put 0 as the next digit of the answer. 
Result so far: 396300.0
The remainder is 47 after subtracting 0 from 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

On to step 9:
If we divide 470 by 141, we get 3 and a remainder of 47.
The number 3 becomes the next digit in our result. 
Result so far: 396300.3
If we subtract 423 from 470, we get 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

Advancing to step 10:
141 can be fit into 470 3 times, resulting in a remainder of 47.
The number 3 becomes the next digit in our result. 
Result so far: 396300.33
If we take 423 away from 470, we end up with 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

The final outcome is 396300.33, with a leftover of 0.047.
