We're dividing 37491715 by 643 
We want to divide 37491715 by 643.

Moving on to step 1:
3 divided by 643 is 0 with a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Grab the next digit (7) from the dividend, add it to 3, then carry on: 37 / 643

Advancing to step 2:
643 can be fit into 37 0 times, resulting in a remainder of 37.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 37 leaves us with 37.
Fetch the next digit (4) from the dividend, attach it to 37 and continue: 374 / 643

On to step 3:
643 goes into 374 0 times with a remainder of 374.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 374 to get 374.
Bring next digit (9) of the dividend behind the 374 and repeat the process: 3749 / 643

Going ahead to step 4:
643 goes into 3749 5 times with a remainder of 534.
The number 5 becomes the next digit in our result. 
Result so far: 5.0
If we take 3215 away from 3749, we end up with 534.
Fetch the next digit (1) from the dividend, attach it to 534 and continue: 5341 / 643

Moving on to step 5:
The number 643 fits into 5341 8 times, leaving a remainder of 197.
Use 8 as the next digit of our solution. 
Result so far: 58.0
Subtract 5144 from 5341 to get 197.
Append the next digit (7) from the dividend to 197 and continue with: 1977 / 643

Step 6:
The number 643 fits into 1977 3 times, leaving a remainder of 48.
Put 3 as the next digit of the answer. 
Result so far: 583.0
Subtracting 1929 from 1977 leaves us with 48.
Grab the next digit (1) from the dividend, add it to 48, then carry on: 481 / 643

Step 7:
643 goes into 481 0 times with a remainder of 481.
The number 0 becomes the next digit in our result. 
Result so far: 5830.0
Deduct 0 from 481 and we're left with 481.
Grab the next digit (5) from the dividend, add it to 481, then carry on: 4815 / 643

Step 8:
4815 divided by 643 is 7 with a remainder of 314.
The next digit of our result is 7. 
Result so far: 58307.0
The remainder is 314 after subtracting 4501 from 4815.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3140, and continue the process.

Step 9:
643 goes into 3140 4 times with a remainder of 568.
The number 4 becomes the next digit in our result. 
Result so far: 58307.4
Deduct 2572 from 3140 and we're left with 568.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5680, and continue the process.

Let's proceed to step 10:
When dividing 5680 by 643, we get 8 with a remainder of 536.
Put 8 as the next digit of the answer. 
Result so far: 58307.48
If we take 5144 away from 5680, we end up with 536.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5360, and continue the process.

On to step 11:
The number 643 fits into 5360 8 times, leaving a remainder of 216.
Write down 8 as next digit of the result. 
Result so far: 58307.488
The remainder is 216 after subtracting 5144 from 5360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2160, and continue the process.

After the division, we end up with 58307.488 and a remainder of 0.0216.
