Let's divide 54639057 by 140
Let's see how many times 140 fits into 54639057.

Going ahead to step 1:
If we divide 5 by 140, we get 0 and a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Append the next digit (4) from the dividend to 5 and continue with: 54 / 140

Moving on to step 2:
The number 140 fits into 54 0 times, leaving a remainder of 54.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 54 to get 54.
Take the next digit (6) from the dividend and append it to 54, then repeat: 546 / 140

Moving on to step 3:
546 divided by 140 is 3 with a remainder of 126.
Use 3 as the next digit of our solution. 
Result so far: 3.0
Deduct 420 from 546 and we're left with 126.
Append the next digit (3) from the dividend to 126 and continue with: 1263 / 140

Advancing to step 4:
If we divide 1263 by 140, we get 9 and a remainder of 3.
Record the quotient 9 as the next digit in the result. 
Result so far: 39.0
Deduct 1260 from 1263 and we're left with 3.
Append the next digit (9) from the dividend to 3 and continue with: 39 / 140

On to step 5:
If we divide 39 by 140, we get 0 and a remainder of 39.
Record the quotient 0 as the next digit in the result. 
Result so far: 390.0
If we subtract 0 from 39, we get 39.
Append the next digit (0) from the dividend to 39 and continue with: 390 / 140

Step 6:
390 divided by 140 is 2 with a remainder of 110.
Write down 2 as next digit of the result. 
Result so far: 3902.0
If we take 280 away from 390, we end up with 110.
Fetch the next digit (5) from the dividend, attach it to 110 and continue: 1105 / 140

On to step 7:
1105 divided by 140 is 7 with a remainder of 125.
Put 7 as the next digit of the answer. 
Result so far: 39027.0
If we subtract 980 from 1105, we get 125.
Bring next digit (7) of the dividend behind the 125 and repeat the process: 1257 / 140

On to step 8:
When dividing 1257 by 140, we get 8 with a remainder of 137.
Write down 8 as next digit of the result. 
Result so far: 390278.0
Subtract 1120 from 1257 to get 137.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1370, and continue the process.

On to step 9:
1370 divided by 140 is 9 with a remainder of 110.
Put 9 as the next digit of the answer. 
Result so far: 390278.9
Subtract 1260 from 1370 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.

Let's proceed to step 10:
140 goes into 1100 7 times with a remainder of 120.
Record the quotient 7 as the next digit in the result. 
Result so far: 390278.97
Subtracting 980 from 1100 leaves us with 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Advancing to step 11:
140 can be fit into 1200 8 times, resulting in a remainder of 80.
Put 8 as the next digit of the answer. 
Result so far: 390278.978
If we take 1120 away from 1200, we end up with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Step 12:
When dividing 800 by 140, we get 5 with a remainder of 100.
Put 5 as the next digit of the answer. 
Result so far: 390278.9785
Subtract 700 from 800 to get 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Step 13:
140 goes into 1000 7 times with a remainder of 20.
Use 7 as the next digit of our solution. 
Result so far: 390278.97857
The remainder is 20 after subtracting 980 from 1000.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Advancing to step 14:
200 divided by 140 is 1 with a remainder of 60.
Record the quotient 1 as the next digit in the result. 
Result so far: 390278.978571
Subtract 140 from 200 to get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Advancing to step 15:
When dividing 600 by 140, we get 4 with a remainder of 40.
Put 4 as the next digit of the answer. 
Result so far: 390278.9785714
Deduct 560 from 600 and we're left with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

On to step 16:
400 divided by 140 is 2 with a remainder of 120.
Record the quotient 2 as the next digit in the result. 
Result so far: 390278.97857142
Subtract 280 from 400 to get 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

The quotient of the division is 390278.97857142, and the remainder is 1.2e-07.
