We look at the division of 15964942 by 61 
We want to figure out the number of times 15964942 can be divided by 61.

Step 1:
61 goes into 1 0 times with a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Append the next digit (5) from the dividend to 1 and continue with: 15 / 61

Advancing to step 2:
The number 61 fits into 15 0 times, leaving a remainder of 15.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 15 and we're left with 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.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
Subtracting 122 from 159 leaves us with 37.
Bring next digit (6) of the dividend behind the 37 and repeat the process: 376 / 61

Let's proceed to step 4:
The number 61 fits into 376 6 times, leaving a remainder of 10.
The next digit of our result is 6. 
Result so far: 26.0
Deduct 366 from 376 and we're left with 10.
Take the next digit (4) from the dividend and append it to 10, then repeat: 104 / 61

Going ahead to step 5:
When dividing 104 by 61, we get 1 with a remainder of 43.
The number 1 becomes the next digit in our result. 
Result so far: 261.0
Subtracting 61 from 104 leaves us with 43.
Fetch the next digit (9) from the dividend, attach it to 43 and continue: 439 / 61

Going ahead to step 6:
61 can be fit into 439 7 times, resulting in a remainder of 12.
The number 7 becomes the next digit in our result. 
Result so far: 2617.0
If we subtract 427 from 439, we get 12.
Take the next digit (4) from the dividend and append it to 12, then repeat: 124 / 61

Step 7:
When dividing 124 by 61, we get 2 with a remainder of 2.
The number 2 becomes the next digit in our result. 
Result so far: 26172.0
Deduct 122 from 124 and we're left with 2.
Grab the next digit (2) from the dividend, add it to 2, then carry on: 22 / 61

On to step 8:
61 can be fit into 22 0 times, resulting in a remainder of 22.
Write down 0 as next digit of the result. 
Result so far: 261720.0
If we subtract 0 from 22, we get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Let's proceed to step 9:
The number 61 fits into 220 3 times, leaving a remainder of 37.
Write down 3 as next digit of the result. 
Result so far: 261720.3
If we subtract 183 from 220, we get 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Going ahead to step 10:
61 can be fit into 370 6 times, resulting in a remainder of 4.
Put 6 as the next digit of the answer. 
Result so far: 261720.36
If we take 366 away from 370, we end up 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 11:
40 divided by 61 is 0 with a remainder of 40.
The next digit of our result is 0. 
Result so far: 261720.36
Deduct 0 from 40 and we're left with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Going ahead to step 12:
400 divided by 61 is 6 with a remainder of 34.
Write down 6 as next digit of the result. 
Result so far: 261720.3606
Deduct 366 from 400 and we're left 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.

Let's proceed to step 13:
When dividing 340 by 61, we get 5 with a remainder of 35.
Use 5 as the next digit of our solution. 
Result so far: 261720.36065
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.

Going ahead to step 14:
61 goes into 350 5 times with a remainder of 45.
Put 5 as the next digit of the answer. 
Result so far: 261720.360655
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.

The quotient of the division is 261720.360655, and the remainder is 4.5e-06.
