86191 ÷ 61 
Let's see how many times 61 fits into 86191.

Advancing to step 1:
61 goes into 8 0 times with a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Fetch the next digit (6) from the dividend, attach it to 8 and continue: 86 / 61

Moving on to step 2:
If we divide 86 by 61, we get 1 and a remainder of 25.
Write down 1 as next digit of the result. 
Result so far: 1.0
Deduct 61 from 86 and we're left with 25.
Include the next digit (1) from the dividend after 25, then repeat: 251 / 61

Moving on to step 3:
61 goes into 251 4 times with a remainder of 7.
The number 4 becomes the next digit in our result. 
Result so far: 14.0
Subtracting 244 from 251 leaves us with 7.
Append the next digit (9) from the dividend to 7 and continue with: 79 / 61

Advancing to step 4:
79 divided by 61 is 1 with a remainder of 18.
Put 1 as the next digit of the answer. 
Result so far: 141.0
Subtracting 61 from 79 leaves us with 18.
Fetch the next digit (1) from the dividend, attach it to 18 and continue: 181 / 61

Moving on to step 5:
181 divided by 61 is 2 with a remainder of 59.
Put 2 as the next digit of the answer. 
Result so far: 1412.0
Subtracting 122 from 181 leaves us with 59.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

Step 6:
When dividing 590 by 61, we get 9 with a remainder of 41.
Record the quotient 9 as the next digit in the result. 
Result so far: 1412.9
If we subtract 549 from 590, we get 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Advancing to step 7:
61 can be fit into 410 6 times, resulting in a remainder of 44.
The next digit of our result is 6. 
Result so far: 1412.96
If we subtract 366 from 410, we get 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Step 8:
61 can be fit into 440 7 times, resulting in a remainder of 13.
Put 7 as the next digit of the answer. 
Result so far: 1412.967
The remainder is 13 after subtracting 427 from 440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Advancing to step 9:
130 divided by 61 is 2 with a remainder of 8.
Use 2 as the next digit of our solution. 
Result so far: 1412.9672
If we take 122 away from 130, we end up with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Advancing to step 10:
If we divide 80 by 61, we get 1 and a remainder of 19.
The next digit of our result is 1. 
Result so far: 1412.96721
Deduct 61 from 80 and we're left with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Step 11:
The number 61 fits into 190 3 times, leaving a remainder of 7.
Record the quotient 3 as the next digit in the result. 
Result so far: 1412.967213
Subtract 183 from 190 to get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Let's proceed to step 12:
The number 61 fits into 70 1 times, leaving a remainder of 9.
Record the quotient 1 as the next digit in the result. 
Result so far: 1412.9672131
The remainder is 9 after subtracting 61 from 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Let's proceed to step 13:
If we divide 90 by 61, we get 1 and a remainder of 29.
Use 1 as the next digit of our solution. 
Result so far: 1412.96721311
Deduct 61 from 90 and we're left with 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

The final result is 1412.96721311 with a remainder of 2.9e-08.
