We're dividing 53859254 by 139 
We want to figure out the number of times 53859254 can be divided by 139.

Step 1:
139 can be fit into 5 0 times, resulting in a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Grab the next digit (3) from the dividend, add it to 5, then carry on: 53 / 139

On to step 2:
If we divide 53 by 139, we get 0 and a remainder of 53.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 53 to get 53.
Take the next digit (8) from the dividend and append it to 53, then repeat: 538 / 139

On to step 3:
139 goes into 538 3 times with a remainder of 121.
Write down 3 as next digit of the result. 
Result so far: 3.0
The remainder is 121 after subtracting 417 from 538.
Append the next digit (5) from the dividend to 121 and continue with: 1215 / 139

Going ahead to step 4:
The number 139 fits into 1215 8 times, leaving a remainder of 103.
Record the quotient 8 as the next digit in the result. 
Result so far: 38.0
If we subtract 1112 from 1215, we get 103.
Take the next digit (9) from the dividend and append it to 103, then repeat: 1039 / 139

Going ahead to step 5:
139 can be fit into 1039 7 times, resulting in a remainder of 66.
Write down 7 as next digit of the result. 
Result so far: 387.0
If we subtract 973 from 1039, we get 66.
Bring next digit (2) of the dividend behind the 66 and repeat the process: 662 / 139

On to step 6:
The number 139 fits into 662 4 times, leaving a remainder of 106.
Write down 4 as next digit of the result. 
Result so far: 3874.0
If we take 556 away from 662, we end up with 106.
Fetch the next digit (5) from the dividend, attach it to 106 and continue: 1065 / 139

Going ahead to step 7:
1065 divided by 139 is 7 with a remainder of 92.
Record the quotient 7 as the next digit in the result. 
Result so far: 38747.0
If we subtract 973 from 1065, we get 92.
Take the next digit (4) from the dividend and append it to 92, then repeat: 924 / 139

Advancing to step 8:
If we divide 924 by 139, we get 6 and a remainder of 90.
The number 6 becomes the next digit in our result. 
Result so far: 387476.0
If we take 834 away from 924, we end up with 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

On to step 9:
When dividing 900 by 139, we get 6 with a remainder of 66.
The next digit of our result is 6. 
Result so far: 387476.6
The remainder is 66 after subtracting 834 from 900.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Advancing to step 10:
If we divide 660 by 139, we get 4 and a remainder of 104.
Use 4 as the next digit of our solution. 
Result so far: 387476.64
Deduct 556 from 660 and we're left with 104.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1040, and continue the process.

Advancing to step 11:
139 goes into 1040 7 times with a remainder of 67.
Put 7 as the next digit of the answer. 
Result so far: 387476.647
Subtracting 973 from 1040 leaves us with 67.
Since there are no more digits in the dividend, we add a zero to the remainder making it 670, and continue the process.

Going ahead to step 12:
670 divided by 139 is 4 with a remainder of 114.
Use 4 as the next digit of our solution. 
Result so far: 387476.6474
The remainder is 114 after subtracting 556 from 670.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1140, and continue the process.

Moving on to step 13:
If we divide 1140 by 139, we get 8 and a remainder of 28.
Write down 8 as next digit of the result. 
Result so far: 387476.64748
Deduct 1112 from 1140 and we're left with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Step 14:
139 can be fit into 280 2 times, resulting in a remainder of 2.
Write down 2 as next digit of the result. 
Result so far: 387476.647482
If we take 278 away from 280, we end up with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Let's proceed to step 15:
20 divided by 139 is 0 with a remainder of 20.
Record the quotient 0 as the next digit in the result. 
Result so far: 387476.647482
If we subtract 0 from 20, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Step 16:
If we divide 200 by 139, we get 1 and a remainder of 61.
Put 1 as the next digit of the answer. 
Result so far: 387476.64748201
The remainder is 61 after subtracting 139 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

Our division results in 387476.64748201 with a remaining 6.1e-08.
