45933445 ÷ 643 
We want to divide 45933445 by 643.

Let's proceed to step 1:
643 can be fit into 4 0 times, resulting in a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Take the next digit (5) from the dividend and append it to 4, then repeat: 45 / 643

Advancing to step 2:
643 can be fit into 45 0 times, resulting in a remainder of 45.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 45 leaves us with 45.
Grab the next digit (9) from the dividend, add it to 45, then carry on: 459 / 643

Let's proceed to step 3:
If we divide 459 by 643, we get 0 and a remainder of 459.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 459 and we're left with 459.
Fetch the next digit (3) from the dividend, attach it to 459 and continue: 4593 / 643

Advancing to step 4:
The number 643 fits into 4593 7 times, leaving a remainder of 92.
Use 7 as the next digit of our solution. 
Result so far: 7.0
If we take 4501 away from 4593, we end up with 92.
Fetch the next digit (3) from the dividend, attach it to 92 and continue: 923 / 643

Advancing to step 5:
643 can be fit into 923 1 times, resulting in a remainder of 280.
Write down 1 as next digit of the result. 
Result so far: 71.0
If we take 643 away from 923, we end up with 280.
Take the next digit (4) from the dividend and append it to 280, then repeat: 2804 / 643

Advancing to step 6:
2804 divided by 643 is 4 with a remainder of 232.
The next digit of our result is 4. 
Result so far: 714.0
Deduct 2572 from 2804 and we're left with 232.
Take the next digit (4) from the dividend and append it to 232, then repeat: 2324 / 643

On to step 7:
643 can be fit into 2324 3 times, resulting in a remainder of 395.
Put 3 as the next digit of the answer. 
Result so far: 7143.0
Subtract 1929 from 2324 to get 395.
Take the next digit (5) from the dividend and append it to 395, then repeat: 3955 / 643

Going ahead to step 8:
643 goes into 3955 6 times with a remainder of 97.
Put 6 as the next digit of the answer. 
Result so far: 71436.0
If we take 3858 away from 3955, we end up with 97.
Since there are no more digits in the dividend, we add a zero to the remainder making it 970, and continue the process.

Advancing to step 9:
When dividing 970 by 643, we get 1 with a remainder of 327.
Put 1 as the next digit of the answer. 
Result so far: 71436.1
Deduct 643 from 970 and we're left with 327.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3270, and continue the process.

Advancing to step 10:
When dividing 3270 by 643, we get 5 with a remainder of 55.
Record the quotient 5 as the next digit in the result. 
Result so far: 71436.15
Deduct 3215 from 3270 and we're left with 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Moving on to step 11:
643 goes into 550 0 times with a remainder of 550.
Write down 0 as next digit of the result. 
Result so far: 71436.15
If we subtract 0 from 550, we get 550.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5500, and continue the process.

Advancing to step 12:
If we divide 5500 by 643, we get 8 and a remainder of 356.
Use 8 as the next digit of our solution. 
Result so far: 71436.1508
If we subtract 5144 from 5500, we get 356.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3560, and continue the process.

Going ahead to step 13:
3560 divided by 643 is 5 with a remainder of 345.
Record the quotient 5 as the next digit in the result. 
Result so far: 71436.15085
Subtract 3215 from 3560 to get 345.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3450, and continue the process.

Moving on to step 14:
3450 divided by 643 is 5 with a remainder of 235.
Record the quotient 5 as the next digit in the result. 
Result so far: 71436.150855
Subtracting 3215 from 3450 leaves us with 235.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2350, and continue the process.

In conclusion, the division gives 71436.150855 with a balance of 2.35e-05.
