37593857 ÷ 640 
Our goal is to divide 37593857 by 640.

Let's proceed to step 1:
3 divided by 640 is 0 with a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Include the next digit (7) from the dividend after 3, then repeat: 37 / 640

Moving on to step 2:
640 goes into 37 0 times with a remainder of 37.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 37 and we're left with 37.
Grab the next digit (5) from the dividend, add it to 37, then carry on: 375 / 640

Step 3:
The number 640 fits into 375 0 times, leaving a remainder of 375.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 375 and we're left with 375.
Bring next digit (9) of the dividend behind the 375 and repeat the process: 3759 / 640

Going ahead to step 4:
3759 divided by 640 is 5 with a remainder of 559.
The number 5 becomes the next digit in our result. 
Result so far: 5.0
If we subtract 3200 from 3759, we get 559.
Include the next digit (3) from the dividend after 559, then repeat: 5593 / 640

Let's proceed to step 5:
640 goes into 5593 8 times with a remainder of 473.
Record the quotient 8 as the next digit in the result. 
Result so far: 58.0
Subtract 5120 from 5593 to get 473.
Include the next digit (8) from the dividend after 473, then repeat: 4738 / 640

Going ahead to step 6:
640 goes into 4738 7 times with a remainder of 258.
The number 7 becomes the next digit in our result. 
Result so far: 587.0
Subtracting 4480 from 4738 leaves us with 258.
Append the next digit (5) from the dividend to 258 and continue with: 2585 / 640

Moving on to step 7:
640 can be fit into 2585 4 times, resulting in a remainder of 25.
Write down 4 as next digit of the result. 
Result so far: 5874.0
Deduct 2560 from 2585 and we're left with 25.
Include the next digit (7) from the dividend after 25, then repeat: 257 / 640

Let's proceed to step 8:
640 can be fit into 257 0 times, resulting in a remainder of 257.
Record the quotient 0 as the next digit in the result. 
Result so far: 58740.0
The remainder is 257 after subtracting 0 from 257.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2570, and continue the process.

Let's proceed to step 9:
640 can be fit into 2570 4 times, resulting in a remainder of 10.
Record the quotient 4 as the next digit in the result. 
Result so far: 58740.4
Subtract 2560 from 2570 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 10:
640 goes into 100 0 times with a remainder of 100.
The next digit of our result is 0. 
Result so far: 58740.4
Deduct 0 from 100 and we're left with 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Moving on to step 11:
640 goes into 1000 1 times with a remainder of 360.
The number 1 becomes the next digit in our result. 
Result so far: 58740.401
If we take 640 away from 1000, we end up with 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3600, and continue the process.

Advancing to step 12:
The number 640 fits into 3600 5 times, leaving a remainder of 400.
Use 5 as the next digit of our solution. 
Result so far: 58740.4015
Deduct 3200 from 3600 and we're left with 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

Step 13:
640 goes into 4000 6 times with a remainder of 160.
Put 6 as the next digit of the answer. 
Result so far: 58740.40156
If we subtract 3840 from 4000, we get 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

On to step 14:
The number 640 fits into 1600 2 times, leaving a remainder of 320.
Use 2 as the next digit of our solution. 
Result so far: 58740.401562
The remainder is 320 after subtracting 1280 from 1600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

Advancing to step 15:
The number 640 fits into 3200 5 times, leaving a remainder of 0.
The next digit of our result is 5. 
Result so far: 58740.4015625
Deduct 3200 from 3200 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 16:
The number 640 fits into 0 0 times, leaving a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 58740.4015625
If we subtract 0 from 0, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final outcome is 58740.4015625, with a leftover of 0.0.
