We look at the division of 64499644 by 436 
Let's see how many times 436 fits into 64499644.

Step 1:
436 goes into 6 0 times with a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Bring next digit (4) of the dividend behind the 6 and repeat the process: 64 / 436

Advancing to step 2:
436 can be fit into 64 0 times, resulting in a remainder of 64.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 64, we get 64.
Grab the next digit (4) from the dividend, add it to 64, then carry on: 644 / 436

Advancing to step 3:
If we divide 644 by 436, we get 1 and a remainder of 208.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Deduct 436 from 644 and we're left with 208.
Take the next digit (9) from the dividend and append it to 208, then repeat: 2089 / 436

Going ahead to step 4:
436 can be fit into 2089 4 times, resulting in a remainder of 345.
Use 4 as the next digit of our solution. 
Result so far: 14.0
Subtract 1744 from 2089 to get 345.
Include the next digit (9) from the dividend after 345, then repeat: 3459 / 436

Going ahead to step 5:
If we divide 3459 by 436, we get 7 and a remainder of 407.
Record the quotient 7 as the next digit in the result. 
Result so far: 147.0
Subtract 3052 from 3459 to get 407.
Fetch the next digit (6) from the dividend, attach it to 407 and continue: 4076 / 436

Advancing to step 6:
When dividing 4076 by 436, we get 9 with a remainder of 152.
Use 9 as the next digit of our solution. 
Result so far: 1479.0
If we subtract 3924 from 4076, we get 152.
Take the next digit (4) from the dividend and append it to 152, then repeat: 1524 / 436

Moving on to step 7:
If we divide 1524 by 436, we get 3 and a remainder of 216.
Use 3 as the next digit of our solution. 
Result so far: 14793.0
Deduct 1308 from 1524 and we're left with 216.
Take the next digit (4) from the dividend and append it to 216, then repeat: 2164 / 436

Let's proceed to step 8:
The number 436 fits into 2164 4 times, leaving a remainder of 420.
Write down 4 as next digit of the result. 
Result so far: 147934.0
If we take 1744 away from 2164, we end up with 420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4200, and continue the process.

Advancing to step 9:
If we divide 4200 by 436, we get 9 and a remainder of 276.
Record the quotient 9 as the next digit in the result. 
Result so far: 147934.9
Subtracting 3924 from 4200 leaves us with 276.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2760, and continue the process.

Step 10:
When dividing 2760 by 436, we get 6 with a remainder of 144.
Use 6 as the next digit of our solution. 
Result so far: 147934.96
If we take 2616 away from 2760, we end up with 144.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1440, and continue the process.

On to step 11:
The number 436 fits into 1440 3 times, leaving a remainder of 132.
Use 3 as the next digit of our solution. 
Result so far: 147934.963
The remainder is 132 after subtracting 1308 from 1440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1320, and continue the process.

Let's proceed to step 12:
If we divide 1320 by 436, we get 3 and a remainder of 12.
Use 3 as the next digit of our solution. 
Result so far: 147934.9633
Subtracting 1308 from 1320 leaves us with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

The final outcome is 147934.9633, with a leftover of 0.00012.
