139 can be fit into 348 2 times, resulting in a remainder of 70.
Put 2 as the next digit of the answer. 
Result so far: 652.0
The remainder is 70 after subtracting 278 from 348.
Take the next digit (3) from the dividend and append it to 70, then repeat: 703 / 139

Let's proceed to step 6:
703 divided by 139 is 5 with a remainder of 8.
Use 5 as the next digit of our solution. 
Result so far: 6525.0
Deduct 695 from 703 and we're left with 8.
Grab the next digit (7) from the dividend, add it to 8, then carry on: 87 / 139

Advancing to step 7:
139 can be fit into 87 0 times, resulting in a remainder of 87.
Put 0 as the next digit of the answer. 
Result so far: 65250.0
Subtract 0 from 87 to get 87.
Fetch the next digit (7) from the dividend, attach it to 87 and continue: 877 / 139

Advancing to step 8:
139 goes into 877 6 times with a remainder of 43.
Record the quotient 6 as the next digit in the result. 
Result so far: 652506.0
Subtract 834 from 877 to get 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Let's proceed to step 9:
430 divided by 139 is 3 with a remainder of 13.
Put 3 as the next digit of the answer. 
Result so far: 652506.3
If we subtract 417 from 430, we get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Moving on to step 10:
When dividing 130 by 139, we get 0 with a remainder of 130.
Use 0 as the next digit of our solution. 
Result so far: 652506.3
Deduct 0 from 130 and we're left with 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

Going ahead to step 11:
1300 divided by 139 is 9 with a remainder of 49.
Use 9 as the next digit of our solution. 
Result so far: 652506.309
The remainder is 49 after subtracting 1251 from 1300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Advancing to step 12:
The number 139 fits into 490 3 times, leaving a remainder of 73.
Put 3 as the next digit of the answer. 
Result so far: 652506.3093
Deduct 417 from 490 and we're left with 73.
Since there are no more digits in the dividend, we add a zero to the remainder making it 730, and continue the process.

Going ahead to step 13:
The number 139 fits into 730 5 times, leaving a remainder of 35.
Put 5 as the next digit of the answer. 
Result so far: 652506.30935
Subtracting 695 from 730 leaves us with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Step 14:
If we divide 350 by 139, we get 2 and a remainder of 72.
The number 2 becomes the next digit in our result. 
Result so far: 652506.309352
Deduct 278 from 350 and we're left with 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Advancing to step 15:
139 goes into 720 5 times with a remainder of 25.
Record the quotient 5 as the next digit in the result. 
Result so far: 652506.3093525
Subtract 695 from 720 to get 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Going ahead to step 16:
If we divide 250 by 139, we get 1 and a remainder of 111.
Write down 1 as next digit of the result. 
Result so far: 652506.30935251
If we subtract 139 from 250, we get 111.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1110, and continue the process.

After the division, we end up with 652506.30935251 and a remainder of 1.11e-07.
