We divide 39396940 by 139
Our goal is to divide 39396940 by 139.

Let's proceed to step 1:
139 goes into 3 0 times with a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Include the next digit (9) from the dividend after 3, then repeat: 39 / 139

On to step 2:
39 divided by 139 is 0 with a remainder of 39.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 39 leaves us with 39.
Fetch the next digit (3) from the dividend, attach it to 39 and continue: 393 / 139

Let's proceed to step 3:
When dividing 393 by 139, we get 2 with a remainder of 115.
Put 2 as the next digit of the answer. 
Result so far: 2.0
If we subtract 278 from 393, we get 115.
Include the next digit (9) from the dividend after 115, then repeat: 1159 / 139

Step 4:
1159 divided by 139 is 8 with a remainder of 47.
The number 8 becomes the next digit in our result. 
Result so far: 28.0
Subtracting 1112 from 1159 leaves us with 47.
Grab the next digit (6) from the dividend, add it to 47, then carry on: 476 / 139

Moving on to step 5:
The number 139 fits into 476 3 times, leaving a remainder of 59.
Put 3 as the next digit of the answer. 
Result so far: 283.0
Subtract 417 from 476 to get 59.
Include the next digit (9) from the dividend after 59, then repeat: 599 / 139

On to step 6:
If we divide 599 by 139, we get 4 and a remainder of 43.
Use 4 as the next digit of our solution. 
Result so far: 2834.0
If we subtract 556 from 599, we get 43.
Fetch the next digit (4) from the dividend, attach it to 43 and continue: 434 / 139

Let's proceed to step 7:
The number 139 fits into 434 3 times, leaving a remainder of 17.
The number 3 becomes the next digit in our result. 
Result so far: 28343.0
Subtract 417 from 434 to get 17.
Bring next digit (0) of the dividend behind the 17 and repeat the process: 170 / 139

Going ahead to step 8:
When dividing 170 by 139, we get 1 with a remainder of 31.
The number 1 becomes the next digit in our result. 
Result so far: 283431.0
Subtract 139 from 170 to get 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Going ahead to step 9:
When dividing 310 by 139, we get 2 with a remainder of 32.
Use 2 as the next digit of our solution. 
Result so far: 283431.2
Deduct 278 from 310 and we're left 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.

Going ahead to step 10:
If we divide 320 by 139, we get 2 and a remainder of 42.
Record the quotient 2 as the next digit in the result. 
Result so far: 283431.22
If we take 278 away from 320, we end up with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

The quotient of the division is 283431.22, and the remainder is 0.042.
