We're dividing 53179643 by 139 
Let's see how many times 139 fits into 53179643.

Going ahead to step 1:
139 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
Deduct 0 from 5 and we're left with 5.
Fetch the next digit (3) from the dividend, attach it to 5 and continue: 53 / 139

Moving on to step 2:
When dividing 53 by 139, we get 0 with a remainder of 53.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 53 to get 53.
Grab the next digit (1) from the dividend, add it to 53, then carry on: 531 / 139

Moving on to step 3:
If we divide 531 by 139, we get 3 and a remainder of 114.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
Subtracting 417 from 531 leaves us with 114.
Take the next digit (7) from the dividend and append it to 114, then repeat: 1147 / 139

Moving on to step 4:
When dividing 1147 by 139, we get 8 with a remainder of 35.
The number 8 becomes the next digit in our result. 
Result so far: 38.0
If we subtract 1112 from 1147, we get 35.
Bring next digit (9) of the dividend behind the 35 and repeat the process: 359 / 139

Step 5:
359 divided by 139 is 2 with a remainder of 81.
Record the quotient 2 as the next digit in the result. 
Result so far: 382.0
If we subtract 278 from 359, we get 81.
Take the next digit (6) from the dividend and append it to 81, then repeat: 816 / 139

Going ahead to step 6:
The number 139 fits into 816 5 times, leaving a remainder of 121.
The next digit of our result is 5. 
Result so far: 3825.0
Deduct 695 from 816 and we're left with 121.
Fetch the next digit (4) from the dividend, attach it to 121 and continue: 1214 / 139

Going ahead to step 7:
When dividing 1214 by 139, we get 8 with a remainder of 102.
Write down 8 as next digit of the result. 
Result so far: 38258.0
The remainder is 102 after subtracting 1112 from 1214.
Append the next digit (3) from the dividend to 102 and continue with: 1023 / 139

Step 8:
When dividing 1023 by 139, we get 7 with a remainder of 50.
Record the quotient 7 as the next digit in the result. 
Result so far: 382587.0
If we take 973 away from 1023, we end up with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Advancing to step 9:
139 can be fit into 500 3 times, resulting in a remainder of 83.
Put 3 as the next digit of the answer. 
Result so far: 382587.3
The remainder is 83 after subtracting 417 from 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 830, and continue the process.

Let's proceed to step 10:
When dividing 830 by 139, we get 5 with a remainder of 135.
Record the quotient 5 as the next digit in the result. 
Result so far: 382587.35
Subtract 695 from 830 to get 135.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1350, and continue the process.

On to step 11:
If we divide 1350 by 139, we get 9 and a remainder of 99.
Use 9 as the next digit of our solution. 
Result so far: 382587.359
Deduct 1251 from 1350 and we're left with 99.
Since there are no more digits in the dividend, we add a zero to the remainder making it 990, and continue the process.

Moving on to step 12:
990 divided by 139 is 7 with a remainder of 17.
Use 7 as the next digit of our solution. 
Result so far: 382587.3597
If we take 973 away from 990, we end up with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Step 13:
If we divide 170 by 139, we get 1 and a remainder of 31.
Record the quotient 1 as the next digit in the result. 
Result so far: 382587.35971
Subtracting 139 from 170 leaves us with 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Moving on to step 14:
139 goes into 310 2 times with a remainder of 32.
Use 2 as the next digit of our solution. 
Result so far: 382587.359712
If we take 278 away from 310, we end up with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Let's proceed to step 15:
320 divided by 139 is 2 with a remainder of 42.
The next digit of our result is 2. 
Result so far: 382587.3597122
The remainder is 42 after subtracting 278 from 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Our division results in 382587.3597122 with a remaining 4.2e-07.
