Let's divide 12443371 by 139
Our goal is to divide 12443371 by 139.

Going ahead to step 1:
When dividing 1 by 139, we get 0 with a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Take the next digit (2) from the dividend and append it to 1, then repeat: 12 / 139

On to step 2:
139 goes into 12 0 times with a remainder of 12.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 12 and we're left with 12.
Grab the next digit (4) from the dividend, add it to 12, then carry on: 124 / 139

Step 3:
When dividing 124 by 139, we get 0 with a remainder of 124.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 124, we get 124.
Take the next digit (4) from the dividend and append it to 124, then repeat: 1244 / 139

Moving on to step 4:
The number 139 fits into 1244 8 times, leaving a remainder of 132.
The next digit of our result is 8. 
Result so far: 8.0
The remainder is 132 after subtracting 1112 from 1244.
Take the next digit (3) from the dividend and append it to 132, then repeat: 1323 / 139

Let's proceed to step 5:
When dividing 1323 by 139, we get 9 with a remainder of 72.
Put 9 as the next digit of the answer. 
Result so far: 89.0
If we take 1251 away from 1323, we end up with 72.
Grab the next digit (3) from the dividend, add it to 72, then carry on: 723 / 139

Going ahead to step 6:
723 divided by 139 is 5 with a remainder of 28.
The next digit of our result is 5. 
Result so far: 895.0
If we subtract 695 from 723, we get 28.
Bring next digit (7) of the dividend behind the 28 and repeat the process: 287 / 139

Advancing to step 7:
139 can be fit into 287 2 times, resulting in a remainder of 9.
Record the quotient 2 as the next digit in the result. 
Result so far: 8952.0
If we take 278 away from 287, we end up with 9.
Take the next digit (1) from the dividend and append it to 9, then repeat: 91 / 139

Step 8:
When dividing 91 by 139, we get 0 with a remainder of 91.
Record the quotient 0 as the next digit in the result. 
Result so far: 89520.0
Subtract 0 from 91 to get 91.
Since there are no more digits in the dividend, we add a zero to the remainder making it 910, and continue the process.

Going ahead to step 9:
910 divided by 139 is 6 with a remainder of 76.
Write down 6 as next digit of the result. 
Result so far: 89520.6
Deduct 834 from 910 and we're left with 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

On to step 10:
760 divided by 139 is 5 with a remainder of 65.
Record the quotient 5 as the next digit in the result. 
Result so far: 89520.65
If we take 695 away from 760, we end up with 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

Step 11:
139 can be fit into 650 4 times, resulting in a remainder of 94.
Use 4 as the next digit of our solution. 
Result so far: 89520.654
If we subtract 556 from 650, we get 94.
Since there are no more digits in the dividend, we add a zero to the remainder making it 940, and continue the process.

Advancing to step 12:
If we divide 940 by 139, we get 6 and a remainder of 106.
Use 6 as the next digit of our solution. 
Result so far: 89520.6546
The remainder is 106 after subtracting 834 from 940.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1060, and continue the process.

Moving on to step 13:
139 can be fit into 1060 7 times, resulting in a remainder of 87.
Write down 7 as next digit of the result. 
Result so far: 89520.65467
The remainder is 87 after subtracting 973 from 1060.
Since there are no more digits in the dividend, we add a zero to the remainder making it 870, and continue the process.

On to step 14:
If we divide 870 by 139, we get 6 and a remainder of 36.
Record the quotient 6 as the next digit in the result. 
Result so far: 89520.654676
Subtracting 834 from 870 leaves us with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Moving on to step 15:
139 can be fit into 360 2 times, resulting in a remainder of 82.
Put 2 as the next digit of the answer. 
Result so far: 89520.6546762
If we subtract 278 from 360, we get 82.
Since there are no more digits in the dividend, we add a zero to the remainder making it 820, and continue the process.

Let's proceed to step 16:
When dividing 820 by 139, we get 5 with a remainder of 125.
Put 5 as the next digit of the answer. 
Result so far: 89520.65467625
Deduct 695 from 820 and we're left with 125.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1250, and continue the process.

The quotient of the division is 89520.65467625, and the remainder is 1.25e-07.
