We're dividing 49643954 by 964 
We want to divide 49643954 by 964.

Let's proceed to step 1:
964 can be fit into 4 0 times, resulting in a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Grab the next digit (9) from the dividend, add it to 4, then carry on: 49 / 964

Moving on to step 2:
964 can be fit into 49 0 times, resulting in a remainder of 49.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 49 after subtracting 0 from 49.
Grab the next digit (6) from the dividend, add it to 49, then carry on: 496 / 964

Step 3:
If we divide 496 by 964, we get 0 and a remainder of 496.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 496 leaves us with 496.
Grab the next digit (4) from the dividend, add it to 496, then carry on: 4964 / 964

Step 4:
When dividing 4964 by 964, we get 5 with a remainder of 144.
Put 5 as the next digit of the answer. 
Result so far: 5.0
Subtracting 4820 from 4964 leaves us with 144.
Take the next digit (3) from the dividend and append it to 144, then repeat: 1443 / 964

Step 5:
964 can be fit into 1443 1 times, resulting in a remainder of 479.
Put 1 as the next digit of the answer. 
Result so far: 51.0
If we take 964 away from 1443, we end up with 479.
Fetch the next digit (9) from the dividend, attach it to 479 and continue: 4799 / 964

Advancing to step 6:
964 goes into 4799 4 times with a remainder of 943.
Use 4 as the next digit of our solution. 
Result so far: 514.0
Deduct 3856 from 4799 and we're left with 943.
Take the next digit (5) from the dividend and append it to 943, then repeat: 9435 / 964

Step 7:
964 goes into 9435 9 times with a remainder of 759.
Write down 9 as next digit of the result. 
Result so far: 5149.0
Subtracting 8676 from 9435 leaves us with 759.
Fetch the next digit (4) from the dividend, attach it to 759 and continue: 7594 / 964

Step 8:
964 goes into 7594 7 times with a remainder of 846.
Put 7 as the next digit of the answer. 
Result so far: 51497.0
The remainder is 846 after subtracting 6748 from 7594.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8460, and continue the process.

Going ahead to step 9:
If we divide 8460 by 964, we get 8 and a remainder of 748.
Use 8 as the next digit of our solution. 
Result so far: 51497.8
Subtract 7712 from 8460 to get 748.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7480, and continue the process.

Let's proceed to step 10:
When dividing 7480 by 964, we get 7 with a remainder of 732.
Put 7 as the next digit of the answer. 
Result so far: 51497.87
If we subtract 6748 from 7480, we get 732.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7320, and continue the process.

Step 11:
If we divide 7320 by 964, we get 7 and a remainder of 572.
Use 7 as the next digit of our solution. 
Result so far: 51497.877
The remainder is 572 after subtracting 6748 from 7320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5720, and continue the process.

The final outcome is 51497.877, with a leftover of 0.0572.
