73041821 ÷ 139 
Our goal is to divide 73041821 by 139.

Going ahead to step 1:
If we divide 7 by 139, we get 0 and a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Fetch the next digit (3) from the dividend, attach it to 7 and continue: 73 / 139

Moving on to step 2:
73 divided by 139 is 0 with a remainder of 73.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 73 leaves us with 73.
Bring next digit (0) of the dividend behind the 73 and repeat the process: 730 / 139

Let's proceed to step 3:
If we divide 730 by 139, we get 5 and a remainder of 35.
The next digit of our result is 5. 
Result so far: 5.0
If we take 695 away from 730, we end up with 35.
Grab the next digit (4) from the dividend, add it to 35, then carry on: 354 / 139

Moving on to step 4:
354 divided by 139 is 2 with a remainder of 76.
Write down 2 as next digit of the result. 
Result so far: 52.0
If we subtract 278 from 354, we get 76.
Bring next digit (1) of the dividend behind the 76 and repeat the process: 761 / 139

On to step 5:
When dividing 761 by 139, we get 5 with a remainder of 66.
The number 5 becomes the next digit in our result. 
Result so far: 525.0
If we take 695 away from 761, we end up with 66.
Bring next digit (8) of the dividend behind the 66 and repeat the process: 668 / 139

On to step 6:
139 goes into 668 4 times with a remainder of 112.
Use 4 as the next digit of our solution. 
Result so far: 5254.0
Deduct 556 from 668 and we're left with 112.
Grab the next digit (2) from the dividend, add it to 112, then carry on: 1122 / 139

Let's proceed to step 7:
1122 divided by 139 is 8 with a remainder of 10.
The next digit of our result is 8. 
Result so far: 52548.0
If we take 1112 away from 1122, we end up with 10.
Grab the next digit (1) from the dividend, add it to 10, then carry on: 101 / 139

Let's proceed to step 8:
101 divided by 139 is 0 with a remainder of 101.
The next digit of our result is 0. 
Result so far: 525480.0
Subtracting 0 from 101 leaves us with 101.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1010, and continue the process.

Step 9:
1010 divided by 139 is 7 with a remainder of 37.
Put 7 as the next digit of the answer. 
Result so far: 525480.7
If we take 973 away from 1010, we end up with 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Advancing to step 10:
The number 139 fits into 370 2 times, leaving a remainder of 92.
Put 2 as the next digit of the answer. 
Result so far: 525480.72
The remainder is 92 after subtracting 278 from 370.
Since there are no more digits in the dividend, we add a zero to the remainder making it 920, and continue the process.

Moving on to step 11:
139 goes into 920 6 times with a remainder of 86.
Record the quotient 6 as the next digit in the result. 
Result so far: 525480.726
Subtracting 834 from 920 leaves us with 86.
Since there are no more digits in the dividend, we add a zero to the remainder making it 860, and continue the process.

Advancing to step 12:
The number 139 fits into 860 6 times, leaving a remainder of 26.
The next digit of our result is 6. 
Result so far: 525480.7266
The remainder is 26 after subtracting 834 from 860.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

The final outcome is 525480.7266, with a leftover of 0.00026.
