Let's divide 86346743 by 61
We want to divide 86346743 by 61.

On 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
Subtract 0 from 8 to get 8.
Append the next digit (6) from the dividend to 8 and continue with: 86 / 61

Step 2:
If we divide 86 by 61, we get 1 and a remainder of 25.
Put 1 as the next digit of the answer. 
Result so far: 1.0
The remainder is 25 after subtracting 61 from 86.
Append the next digit (3) from the dividend to 25 and continue with: 253 / 61

Moving on to step 3:
61 can be fit into 253 4 times, resulting in a remainder of 9.
Use 4 as the next digit of our solution. 
Result so far: 14.0
The remainder is 9 after subtracting 244 from 253.
Bring next digit (4) of the dividend behind the 9 and repeat the process: 94 / 61

On to step 4:
When dividing 94 by 61, we get 1 with a remainder of 33.
The next digit of our result is 1. 
Result so far: 141.0
Subtract 61 from 94 to get 33.
Take the next digit (6) from the dividend and append it to 33, then repeat: 336 / 61

Step 5:
336 divided by 61 is 5 with a remainder of 31.
Put 5 as the next digit of the answer. 
Result so far: 1415.0
Deduct 305 from 336 and we're left with 31.
Fetch the next digit (7) from the dividend, attach it to 31 and continue: 317 / 61

Advancing to step 6:
61 goes into 317 5 times with a remainder of 12.
Use 5 as the next digit of our solution. 
Result so far: 14155.0
Subtracting 305 from 317 leaves us with 12.
Bring next digit (4) of the dividend behind the 12 and repeat the process: 124 / 61

On to step 7:
When dividing 124 by 61, we get 2 with a remainder of 2.
Record the quotient 2 as the next digit in the result. 
Result so far: 141552.0
If we subtract 122 from 124, we get 2.
Include the next digit (3) from the dividend after 2, then repeat: 23 / 61

Step 8:
61 goes into 23 0 times with a remainder of 23.
The next digit of our result is 0. 
Result so far: 1415520.0
If we subtract 0 from 23, we get 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Going ahead to step 9:
61 can be fit into 230 3 times, resulting in a remainder of 47.
The next digit of our result is 3. 
Result so far: 1415520.3
The remainder is 47 after subtracting 183 from 230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

Advancing to step 10:
If we divide 470 by 61, we get 7 and a remainder of 43.
The number 7 becomes the next digit in our result. 
Result so far: 1415520.37
Deduct 427 from 470 and we're left with 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

On to step 11:
61 goes into 430 7 times with a remainder of 3.
Write down 7 as next digit of the result. 
Result so far: 1415520.377
The remainder is 3 after subtracting 427 from 430.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Our division results in 1415520.377 with a remaining 0.0003.
