64621189 ÷ 586 
We want to divide 64621189 by 586.

Going ahead to step 1:
586 can be fit into 6 0 times, resulting in a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Fetch the next digit (4) from the dividend, attach it to 6 and continue: 64 / 586

Going ahead to step 2:
586 can be fit into 64 0 times, resulting in a remainder of 64.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 64 to get 64.
Bring next digit (6) of the dividend behind the 64 and repeat the process: 646 / 586

Advancing to step 3:
When dividing 646 by 586, we get 1 with a remainder of 60.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtract 586 from 646 to get 60.
Fetch the next digit (2) from the dividend, attach it to 60 and continue: 602 / 586

Moving on to step 4:
If we divide 602 by 586, we get 1 and a remainder of 16.
The next digit of our result is 1. 
Result so far: 11.0
Subtract 586 from 602 to get 16.
Append the next digit (1) from the dividend to 16 and continue with: 161 / 586

Moving on to step 5:
586 can be fit into 161 0 times, resulting in a remainder of 161.
Put 0 as the next digit of the answer. 
Result so far: 110.0
If we subtract 0 from 161, we get 161.
Fetch the next digit (1) from the dividend, attach it to 161 and continue: 1611 / 586

Advancing to step 6:
586 goes into 1611 2 times with a remainder of 439.
The number 2 becomes the next digit in our result. 
Result so far: 1102.0
If we take 1172 away from 1611, we end up with 439.
Take the next digit (8) from the dividend and append it to 439, then repeat: 4398 / 586

Step 7:
586 goes into 4398 7 times with a remainder of 296.
The number 7 becomes the next digit in our result. 
Result so far: 11027.0
The remainder is 296 after subtracting 4102 from 4398.
Take the next digit (9) from the dividend and append it to 296, then repeat: 2969 / 586

Step 8:
586 can be fit into 2969 5 times, resulting in a remainder of 39.
Put 5 as the next digit of the answer. 
Result so far: 110275.0
Subtracting 2930 from 2969 leaves us 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.

Moving on to step 9:
If we divide 390 by 586, we get 0 and a remainder of 390.
Write down 0 as next digit of the result. 
Result so far: 110275.0
Deduct 0 from 390 and we're left with 390.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3900, and continue the process.

On to step 10:
586 can be fit into 3900 6 times, resulting in a remainder of 384.
The number 6 becomes the next digit in our result. 
Result so far: 110275.06
The remainder is 384 after subtracting 3516 from 3900.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3840, and continue the process.

Step 11:
If we divide 3840 by 586, we get 6 and a remainder of 324.
Use 6 as the next digit of our solution. 
Result so far: 110275.066
Subtracting 3516 from 3840 leaves us with 324.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3240, and continue the process.

In conclusion, the division gives 110275.066 with a balance of 0.0324.
