73145091 divided by 61 
Our goal is to divide 73145091 by 61.

Going ahead to step 1:
7 divided by 61 is 0 with a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Append the next digit (3) from the dividend to 7 and continue with: 73 / 61

Step 2:
61 goes into 73 1 times with a remainder of 12.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
The remainder is 12 after subtracting 61 from 73.
Fetch the next digit (1) from the dividend, attach it to 12 and continue: 121 / 61

On to step 3:
61 goes into 121 1 times with a remainder of 60.
Write down 1 as next digit of the result. 
Result so far: 11.0
Deduct 61 from 121 and we're left with 60.
Include the next digit (4) from the dividend after 60, then repeat: 604 / 61

Step 4:
The number 61 fits into 604 9 times, leaving a remainder of 55.
Record the quotient 9 as the next digit in the result. 
Result so far: 119.0
Deduct 549 from 604 and we're left with 55.
Bring next digit (5) of the dividend behind the 55 and repeat the process: 555 / 61

Step 5:
61 can be fit into 555 9 times, resulting in a remainder of 6.
The next digit of our result is 9. 
Result so far: 1199.0
If we subtract 549 from 555, we get 6.
Append the next digit (0) from the dividend to 6 and continue with: 60 / 61

Moving on to step 6:
The number 61 fits into 60 0 times, leaving a remainder of 60.
Write down 0 as next digit of the result. 
Result so far: 11990.0
Subtracting 0 from 60 leaves us with 60.
Append the next digit (9) from the dividend to 60 and continue with: 609 / 61

Step 7:
61 can be fit into 609 9 times, resulting in a remainder of 60.
The next digit of our result is 9. 
Result so far: 119909.0
If we take 549 away from 609, we end up with 60.
Append the next digit (1) from the dividend to 60 and continue with: 601 / 61

Let's proceed to step 8:
61 goes into 601 9 times with a remainder of 52.
Record the quotient 9 as the next digit in the result. 
Result so far: 1199099.0
Deduct 549 from 601 and we're left with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Step 9:
520 divided by 61 is 8 with a remainder of 32.
The number 8 becomes the next digit in our result. 
Result so far: 1199099.8
If we subtract 488 from 520, we get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

On to step 10:
The number 61 fits into 320 5 times, leaving a remainder of 15.
Put 5 as the next digit of the answer. 
Result so far: 1199099.85
The remainder is 15 after subtracting 305 from 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

On to step 11:
If we divide 150 by 61, we get 2 and a remainder of 28.
The next digit of our result is 2. 
Result so far: 1199099.852
If we take 122 away from 150, we end up with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Step 12:
The number 61 fits into 280 4 times, leaving a remainder of 36.
Use 4 as the next digit of our solution. 
Result so far: 1199099.8524
If we take 244 away from 280, we end up 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 13:
When dividing 360 by 61, we get 5 with a remainder of 55.
The number 5 becomes the next digit in our result. 
Result so far: 1199099.85245
If we take 305 away from 360, we end up with 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Going ahead to step 14:
550 divided by 61 is 9 with a remainder of 1.
Record the quotient 9 as the next digit in the result. 
Result so far: 1199099.852459
If we take 549 away from 550, we end up with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Moving on to step 15:
If we divide 10 by 61, we get 0 and a remainder of 10.
Put 0 as the next digit of the answer. 
Result so far: 1199099.852459
If we subtract 0 from 10, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 16:
When dividing 100 by 61, we get 1 with a remainder of 39.
Use 1 as the next digit of our solution. 
Result so far: 1199099.85245901
If we take 61 away from 100, we end up with 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

The final result is 1199099.85245901 with a remainder of 3.9e-08.
