45469643 ÷ 170 
Let's see how many times 170 fits into 45469643.

Moving on to step 1:
If we divide 4 by 170, we get 0 and a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Fetch the next digit (5) from the dividend, attach it to 4 and continue: 45 / 170

Step 2:
The number 170 fits into 45 0 times, leaving a remainder of 45.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 45, we end up with 45.
Grab the next digit (4) from the dividend, add it to 45, then carry on: 454 / 170

Moving on to step 3:
170 goes into 454 2 times with a remainder of 114.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Subtract 340 from 454 to get 114.
Append the next digit (6) from the dividend to 114 and continue with: 1146 / 170

On to step 4:
170 goes into 1146 6 times with a remainder of 126.
Put 6 as the next digit of the answer. 
Result so far: 26.0
Subtracting 1020 from 1146 leaves us with 126.
Take the next digit (9) from the dividend and append it to 126, then repeat: 1269 / 170

Step 5:
170 can be fit into 1269 7 times, resulting in a remainder of 79.
Record the quotient 7 as the next digit in the result. 
Result so far: 267.0
The remainder is 79 after subtracting 1190 from 1269.
Append the next digit (6) from the dividend to 79 and continue with: 796 / 170

Advancing to step 6:
170 goes into 796 4 times with a remainder of 116.
Use 4 as the next digit of our solution. 
Result so far: 2674.0
The remainder is 116 after subtracting 680 from 796.
Grab the next digit (4) from the dividend, add it to 116, then carry on: 1164 / 170

Advancing to step 7:
1164 divided by 170 is 6 with a remainder of 144.
The next digit of our result is 6. 
Result so far: 26746.0
The remainder is 144 after subtracting 1020 from 1164.
Include the next digit (3) from the dividend after 144, then repeat: 1443 / 170

Let's proceed to step 8:
1443 divided by 170 is 8 with a remainder of 83.
Put 8 as the next digit of the answer. 
Result so far: 267468.0
If we take 1360 away from 1443, we end up with 83.
Since there are no more digits in the dividend, we add a zero to the remainder making it 830, and continue the process.

On to step 9:
830 divided by 170 is 4 with a remainder of 150.
Put 4 as the next digit of the answer. 
Result so far: 267468.4
The remainder is 150 after subtracting 680 from 830.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

Step 10:
1500 divided by 170 is 8 with a remainder of 140.
Write down 8 as next digit of the result. 
Result so far: 267468.48
Subtract 1360 from 1500 to get 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

Let's proceed to step 11:
When dividing 1400 by 170, we get 8 with a remainder of 40.
Use 8 as the next digit of our solution. 
Result so far: 267468.488
Deduct 1360 from 1400 and we're left with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Our division results in 267468.488 with a remaining 0.004.
