We look at the division of 15910019 by 61 
Our goal is to divide 15910019 by 61.

Let's proceed to step 1:
1 divided by 61 is 0 with a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Take the next digit (5) from the dividend and append it to 1, then repeat: 15 / 61

Advancing to step 2:
61 goes into 15 0 times with a remainder of 15.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 15 to get 15.
Include the next digit (9) from the dividend after 15, then repeat: 159 / 61

Step 3:
61 can be fit into 159 2 times, resulting in a remainder of 37.
Put 2 as the next digit of the answer. 
Result so far: 2.0
The remainder is 37 after subtracting 122 from 159.
Take the next digit (1) from the dividend and append it to 37, then repeat: 371 / 61

Going ahead to step 4:
61 can be fit into 371 6 times, resulting in a remainder of 5.
Record the quotient 6 as the next digit in the result. 
Result so far: 26.0
Subtract 366 from 371 to get 5.
Include the next digit (0) from the dividend after 5, then repeat: 50 / 61

Advancing to step 5:
The number 61 fits into 50 0 times, leaving a remainder of 50.
Use 0 as the next digit of our solution. 
Result so far: 260.0
Subtract 0 from 50 to get 50.
Include the next digit (0) from the dividend after 50, then repeat: 500 / 61

Step 6:
500 divided by 61 is 8 with a remainder of 12.
Use 8 as the next digit of our solution. 
Result so far: 2608.0
Deduct 488 from 500 and we're left with 12.
Include the next digit (1) from the dividend after 12, then repeat: 121 / 61

Going ahead to step 7:
61 goes into 121 1 times with a remainder of 60.
The number 1 becomes the next digit in our result. 
Result so far: 26081.0
If we take 61 away from 121, we end up with 60.
Bring next digit (9) of the dividend behind the 60 and repeat the process: 609 / 61

Advancing to step 8:
61 goes into 609 9 times with a remainder of 60.
Record the quotient 9 as the next digit in the result. 
Result so far: 260819.0
Subtract 549 from 609 to get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Advancing to step 9:
The number 61 fits into 600 9 times, leaving a remainder of 51.
Put 9 as the next digit of the answer. 
Result so far: 260819.9
Deduct 549 from 600 and we're left with 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

Step 10:
61 can be fit into 510 8 times, resulting in a remainder of 22.
Write down 8 as next digit of the result. 
Result so far: 260819.98
Deduct 488 from 510 and we're left with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

On to step 11:
If we divide 220 by 61, we get 3 and a remainder of 37.
Record the quotient 3 as the next digit in the result. 
Result so far: 260819.983
Deduct 183 from 220 and we're left 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 12:
When dividing 370 by 61, we get 6 with a remainder of 4.
The next digit of our result is 6. 
Result so far: 260819.9836
Deduct 366 from 370 and we're left with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Going ahead to step 13:
61 can be fit into 40 0 times, resulting in a remainder of 40.
The number 0 becomes the next digit in our result. 
Result so far: 260819.9836
If we subtract 0 from 40, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

On to step 14:
61 can be fit into 400 6 times, resulting in a remainder of 34.
The number 6 becomes the next digit in our result. 
Result so far: 260819.983606
Subtracting 366 from 400 leaves us with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Moving on to step 15:
If we divide 340 by 61, we get 5 and a remainder of 35.
Write down 5 as next digit of the result. 
Result so far: 260819.9836065
If we take 305 away from 340, we end up 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 16:
350 divided by 61 is 5 with a remainder of 45.
Put 5 as the next digit of the answer. 
Result so far: 260819.98360655
Subtracting 305 from 350 leaves us with 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

After the division, we end up with 260819.98360655 and a remainder of 4.5e-08.
