55403481 ÷ 140 
We want to divide 55403481 by 140.

Step 1:
5 divided by 140 is 0 with a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Grab the next digit (5) from the dividend, add it to 5, then carry on: 55 / 140

Advancing to step 2:
If we divide 55 by 140, we get 0 and a remainder of 55.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 55 to get 55.
Grab the next digit (4) from the dividend, add it to 55, then carry on: 554 / 140

Moving on to step 3:
When dividing 554 by 140, we get 3 with a remainder of 134.
Put 3 as the next digit of the answer. 
Result so far: 3.0
If we take 420 away from 554, we end up with 134.
Grab the next digit (0) from the dividend, add it to 134, then carry on: 1340 / 140

On to step 4:
140 goes into 1340 9 times with a remainder of 80.
Write down 9 as next digit of the result. 
Result so far: 39.0
Subtract 1260 from 1340 to get 80.
Append the next digit (3) from the dividend to 80 and continue with: 803 / 140

Moving on to step 5:
The number 140 fits into 803 5 times, leaving a remainder of 103.
Record the quotient 5 as the next digit in the result. 
Result so far: 395.0
If we take 700 away from 803, we end up with 103.
Grab the next digit (4) from the dividend, add it to 103, then carry on: 1034 / 140

Advancing to step 6:
When dividing 1034 by 140, we get 7 with a remainder of 54.
Write down 7 as next digit of the result. 
Result so far: 3957.0
Deduct 980 from 1034 and we're left with 54.
Grab the next digit (8) from the dividend, add it to 54, then carry on: 548 / 140

Going ahead to step 7:
548 divided by 140 is 3 with a remainder of 128.
The number 3 becomes the next digit in our result. 
Result so far: 39573.0
Subtracting 420 from 548 leaves us with 128.
Take the next digit (1) from the dividend and append it to 128, then repeat: 1281 / 140

Advancing to step 8:
The number 140 fits into 1281 9 times, leaving a remainder of 21.
The next digit of our result is 9. 
Result so far: 395739.0
If we subtract 1260 from 1281, we get 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

On to step 9:
If we divide 210 by 140, we get 1 and a remainder of 70.
Record the quotient 1 as the next digit in the result. 
Result so far: 395739.1
If we subtract 140 from 210, we get 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Let's proceed to step 10:
When dividing 700 by 140, we get 5 with a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 395739.15
Deduct 700 from 700 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 11:
When dividing 0 by 140, we get 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 395739.15
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 12:
0 divided by 140 is 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 395739.15
If we subtract 0 from 0, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Our division results in 395739.15 with a remaining 0.0.
