We're dividing 45473326 by 643 
Our goal is to divide 45473326 by 643.

Going ahead to step 1:
643 goes into 4 0 times with a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Fetch the next digit (5) from the dividend, attach it to 4 and continue: 45 / 643

Step 2:
643 can be fit into 45 0 times, resulting in a remainder of 45.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 45 to get 45.
Fetch the next digit (4) from the dividend, attach it to 45 and continue: 454 / 643

Advancing to step 3:
643 can be fit into 454 0 times, resulting in a remainder of 454.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 454 after subtracting 0 from 454.
Include the next digit (7) from the dividend after 454, then repeat: 4547 / 643

Going ahead to step 4:
When dividing 4547 by 643, we get 7 with a remainder of 46.
Record the quotient 7 as the next digit in the result. 
Result so far: 7.0
The remainder is 46 after subtracting 4501 from 4547.
Grab the next digit (3) from the dividend, add it to 46, then carry on: 463 / 643

Moving on to step 5:
The number 643 fits into 463 0 times, leaving a remainder of 463.
The number 0 becomes the next digit in our result. 
Result so far: 70.0
If we take 0 away from 463, we end up with 463.
Bring next digit (3) of the dividend behind the 463 and repeat the process: 4633 / 643

Step 6:
643 goes into 4633 7 times with a remainder of 132.
Write down 7 as next digit of the result. 
Result so far: 707.0
Subtract 4501 from 4633 to get 132.
Bring next digit (2) of the dividend behind the 132 and repeat the process: 1322 / 643

Advancing to step 7:
The number 643 fits into 1322 2 times, leaving a remainder of 36.
The number 2 becomes the next digit in our result. 
Result so far: 7072.0
Subtract 1286 from 1322 to get 36.
Include the next digit (6) from the dividend after 36, then repeat: 366 / 643

Advancing to step 8:
643 goes into 366 0 times with a remainder of 366.
The next digit of our result is 0. 
Result so far: 70720.0
If we take 0 away from 366, we end up with 366.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3660, and continue the process.

Let's proceed to step 9:
643 can be fit into 3660 5 times, resulting in a remainder of 445.
The next digit of our result is 5. 
Result so far: 70720.5
Subtract 3215 from 3660 to get 445.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4450, and continue the process.

Moving on to step 10:
The number 643 fits into 4450 6 times, leaving a remainder of 592.
Use 6 as the next digit of our solution. 
Result so far: 70720.56
Subtract 3858 from 4450 to get 592.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5920, and continue the process.

Step 11:
If we divide 5920 by 643, we get 9 and a remainder of 133.
The number 9 becomes the next digit in our result. 
Result so far: 70720.569
If we subtract 5787 from 5920, we get 133.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1330, and continue the process.

Advancing to step 12:
1330 divided by 643 is 2 with a remainder of 44.
The number 2 becomes the next digit in our result. 
Result so far: 70720.5692
If we take 1286 away from 1330, we end up with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

On to step 13:
643 can be fit into 440 0 times, resulting in a remainder of 440.
Put 0 as the next digit of the answer. 
Result so far: 70720.5692
If we take 0 away from 440, we end up with 440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4400, and continue the process.

Moving on to step 14:
4400 divided by 643 is 6 with a remainder of 542.
The number 6 becomes the next digit in our result. 
Result so far: 70720.569206
Subtracting 3858 from 4400 leaves us with 542.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5420, and continue the process.

Moving on to step 15:
When dividing 5420 by 643, we get 8 with a remainder of 276.
Record the quotient 8 as the next digit in the result. 
Result so far: 70720.5692068
Subtract 5144 from 5420 to get 276.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2760, and continue the process.

On to step 16:
2760 divided by 643 is 4 with a remainder of 188.
Write down 4 as next digit of the result. 
Result so far: 70720.56920684
If we take 2572 away from 2760, we end up with 188.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1880, and continue the process.

The quotient of the division is 70720.56920684, and the remainder is 1.88e-07.
