We're dividing 59803710 by 644 
We want to divide 59803710 by 644.

On to step 1:
The number 644 fits into 5 0 times, leaving a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Bring next digit (9) of the dividend behind the 5 and repeat the process: 59 / 644

Step 2:
644 can be fit into 59 0 times, resulting in a remainder of 59.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 59, we end up with 59.
Append the next digit (8) from the dividend to 59 and continue with: 598 / 644

Going ahead to step 3:
If we divide 598 by 644, we get 0 and a remainder of 598.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 598 to get 598.
Include the next digit (0) from the dividend after 598, then repeat: 5980 / 644

Advancing to step 4:
The number 644 fits into 5980 9 times, leaving a remainder of 184.
Put 9 as the next digit of the answer. 
Result so far: 9.0
The remainder is 184 after subtracting 5796 from 5980.
Include the next digit (3) from the dividend after 184, then repeat: 1843 / 644

Step 5:
If we divide 1843 by 644, we get 2 and a remainder of 555.
Write down 2 as next digit of the result. 
Result so far: 92.0
Subtracting 1288 from 1843 leaves us with 555.
Include the next digit (7) from the dividend after 555, then repeat: 5557 / 644

Advancing to step 6:
644 can be fit into 5557 8 times, resulting in a remainder of 405.
The next digit of our result is 8. 
Result so far: 928.0
If we take 5152 away from 5557, we end up with 405.
Fetch the next digit (1) from the dividend, attach it to 405 and continue: 4051 / 644

Step 7:
When dividing 4051 by 644, we get 6 with a remainder of 187.
Use 6 as the next digit of our solution. 
Result so far: 9286.0
If we take 3864 away from 4051, we end up with 187.
Fetch the next digit (0) from the dividend, attach it to 187 and continue: 1870 / 644

Going ahead to step 8:
If we divide 1870 by 644, we get 2 and a remainder of 582.
Use 2 as the next digit of our solution. 
Result so far: 92862.0
Subtract 1288 from 1870 to get 582.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5820, and continue the process.

Moving on to step 9:
5820 divided by 644 is 9 with a remainder of 24.
Use 9 as the next digit of our solution. 
Result so far: 92862.9
Deduct 5796 from 5820 and we're left with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Let's proceed to step 10:
644 can be fit into 240 0 times, resulting in a remainder of 240.
The next digit of our result is 0. 
Result so far: 92862.9
If we subtract 0 from 240, we get 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

Advancing to step 11:
2400 divided by 644 is 3 with a remainder of 468.
The next digit of our result is 3. 
Result so far: 92862.903
Deduct 1932 from 2400 and we're left with 468.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4680, and continue the process.

On to step 12:
The number 644 fits into 4680 7 times, leaving a remainder of 172.
The next digit of our result is 7. 
Result so far: 92862.9037
Subtract 4508 from 4680 to get 172.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1720, and continue the process.

Advancing to step 13:
If we divide 1720 by 644, we get 2 and a remainder of 432.
Use 2 as the next digit of our solution. 
Result so far: 92862.90372
The remainder is 432 after subtracting 1288 from 1720.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4320, and continue the process.

Let's proceed to step 14:
644 goes into 4320 6 times with a remainder of 456.
Write down 6 as next digit of the result. 
Result so far: 92862.903726
If we take 3864 away from 4320, we end up with 456.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4560, and continue the process.

Going ahead to step 15:
644 goes into 4560 7 times with a remainder of 52.
The number 7 becomes the next digit in our result. 
Result so far: 92862.9037267
If we subtract 4508 from 4560, we get 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Moving on to step 16:
If we divide 520 by 644, we get 0 and a remainder of 520.
Put 0 as the next digit of the answer. 
Result so far: 92862.9037267
Subtract 0 from 520 to get 520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5200, and continue the process.

The quotient of the division is 92862.9037267, and the remainder is 5.2e-07.
