We divide 64356587 by 91
Our goal is to divide 64356587 by 91.

Step 1:
6 divided by 91 is 0 with a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Take the next digit (4) from the dividend and append it to 6, then repeat: 64 / 91

On to step 2:
91 goes into 64 0 times with a remainder of 64.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 64 to get 64.
Bring next digit (3) of the dividend behind the 64 and repeat the process: 643 / 91

Advancing to step 3:
If we divide 643 by 91, we get 7 and a remainder of 6.
Put 7 as the next digit of the answer. 
Result so far: 7.0
If we take 637 away from 643, we end up with 6.
Take the next digit (5) from the dividend and append it to 6, then repeat: 65 / 91

Advancing to step 4:
91 goes into 65 0 times with a remainder of 65.
The next digit of our result is 0. 
Result so far: 70.0
If we take 0 away from 65, we end up with 65.
Fetch the next digit (6) from the dividend, attach it to 65 and continue: 656 / 91

Moving on to step 5:
The number 91 fits into 656 7 times, leaving a remainder of 19.
Put 7 as the next digit of the answer. 
Result so far: 707.0
Deduct 637 from 656 and we're left with 19.
Take the next digit (5) from the dividend and append it to 19, then repeat: 195 / 91

Moving on to step 6:
If we divide 195 by 91, we get 2 and a remainder of 13.
Record the quotient 2 as the next digit in the result. 
Result so far: 7072.0
Subtracting 182 from 195 leaves us with 13.
Include the next digit (8) from the dividend after 13, then repeat: 138 / 91

Let's proceed to step 7:
If we divide 138 by 91, we get 1 and a remainder of 47.
Record the quotient 1 as the next digit in the result. 
Result so far: 70721.0
The remainder is 47 after subtracting 91 from 138.
Bring next digit (7) of the dividend behind the 47 and repeat the process: 477 / 91

Step 8:
The number 91 fits into 477 5 times, leaving a remainder of 22.
Write down 5 as next digit of the result. 
Result so far: 707215.0
Subtract 455 from 477 to get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Advancing to step 9:
91 can be fit into 220 2 times, resulting in a remainder of 38.
Use 2 as the next digit of our solution. 
Result so far: 707215.2
If we take 182 away from 220, we end up with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

On to step 10:
When dividing 380 by 91, we get 4 with a remainder of 16.
The next digit of our result is 4. 
Result so far: 707215.24
The remainder is 16 after subtracting 364 from 380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

On to step 11:
If we divide 160 by 91, we get 1 and a remainder of 69.
The next digit of our result is 1. 
Result so far: 707215.241
If we subtract 91 from 160, we get 69.
Since there are no more digits in the dividend, we add a zero to the remainder making it 690, and continue the process.

Step 12:
If we divide 690 by 91, we get 7 and a remainder of 53.
Write down 7 as next digit of the result. 
Result so far: 707215.2417
If we take 637 away from 690, we end up with 53.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

Advancing to step 13:
91 can be fit into 530 5 times, resulting in a remainder of 75.
Use 5 as the next digit of our solution. 
Result so far: 707215.24175
Subtracting 455 from 530 leaves us with 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Step 14:
750 divided by 91 is 8 with a remainder of 22.
Record the quotient 8 as the next digit in the result. 
Result so far: 707215.241758
If we take 728 away from 750, we end up with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Moving on to step 15:
220 divided by 91 is 2 with a remainder of 38.
Put 2 as the next digit of the answer. 
Result so far: 707215.2417582
If we take 182 away from 220, we end up with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

On to step 16:
When dividing 380 by 91, we get 4 with a remainder of 16.
Use 4 as the next digit of our solution. 
Result so far: 707215.24175824
Subtracting 364 from 380 leaves us with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

The final outcome is 707215.24175824, with a leftover of 1.6e-08.
