83121705 ÷ 61 
We want to figure out the number of times 83121705 can be divided by 61.

Advancing to step 1:
If we divide 8 by 61, we get 0 and a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Append the next digit (3) from the dividend to 8 and continue with: 83 / 61

Step 2:
When dividing 83 by 61, we get 1 with a remainder of 22.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtract 61 from 83 to get 22.
Append the next digit (1) from the dividend to 22 and continue with: 221 / 61

Going ahead to step 3:
When dividing 221 by 61, we get 3 with a remainder of 38.
Write down 3 as next digit of the result. 
Result so far: 13.0
If we take 183 away from 221, we end up with 38.
Bring next digit (2) of the dividend behind the 38 and repeat the process: 382 / 61

Moving on to step 4:
When dividing 382 by 61, we get 6 with a remainder of 16.
The next digit of our result is 6. 
Result so far: 136.0
Subtract 366 from 382 to get 16.
Fetch the next digit (1) from the dividend, attach it to 16 and continue: 161 / 61

Advancing to step 5:
When dividing 161 by 61, we get 2 with a remainder of 39.
Use 2 as the next digit of our solution. 
Result so far: 1362.0
Subtract 122 from 161 to get 39.
Append the next digit (7) from the dividend to 39 and continue with: 397 / 61

Moving on to step 6:
When dividing 397 by 61, we get 6 with a remainder of 31.
The number 6 becomes the next digit in our result. 
Result so far: 13626.0
Deduct 366 from 397 and we're left with 31.
Bring next digit (0) of the dividend behind the 31 and repeat the process: 310 / 61

Let's proceed to step 7:
When dividing 310 by 61, we get 5 with a remainder of 5.
Write down 5 as next digit of the result. 
Result so far: 136265.0
Subtracting 305 from 310 leaves us with 5.
Take the next digit (5) from the dividend and append it to 5, then repeat: 55 / 61

Let's proceed to step 8:
When dividing 55 by 61, we get 0 with a remainder of 55.
Write down 0 as next digit of the result. 
Result so far: 1362650.0
Subtract 0 from 55 to get 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Advancing to step 9:
When dividing 550 by 61, we get 9 with a remainder of 1.
The number 9 becomes the next digit in our result. 
Result so far: 1362650.9
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.

Advancing to step 10:
The number 61 fits into 10 0 times, leaving a remainder of 10.
The number 0 becomes the next digit in our result. 
Result so far: 1362650.9
Subtracting 0 from 10 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 11:
When dividing 100 by 61, we get 1 with a remainder of 39.
The number 1 becomes the next digit in our result. 
Result so far: 1362650.901
Subtract 61 from 100 to get 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Moving on to step 12:
When dividing 390 by 61, we get 6 with a remainder of 24.
Write down 6 as next digit of the result. 
Result so far: 1362650.9016
Subtract 366 from 390 to get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Going ahead to step 13:
The number 61 fits into 240 3 times, leaving a remainder of 57.
Put 3 as the next digit of the answer. 
Result so far: 1362650.90163
The remainder is 57 after subtracting 183 from 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

Let's proceed to step 14:
When dividing 570 by 61, we get 9 with a remainder of 21.
The next digit of our result is 9. 
Result so far: 1362650.901639
Subtracting 549 from 570 leaves us with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

On to step 15:
61 goes into 210 3 times with a remainder of 27.
The number 3 becomes the next digit in our result. 
Result so far: 1362650.9016393
Deduct 183 from 210 and we're left with 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Advancing to step 16:
The number 61 fits into 270 4 times, leaving a remainder of 26.
Write down 4 as next digit of the result. 
Result so far: 1362650.90163934
The remainder is 26 after subtracting 244 from 270.
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 result is 1362650.90163934 with a remainder of 2.6e-08.
