61388900 ÷ 170 
We want to figure out the number of times 61388900 can be divided by 170.

Step 1:
The number 170 fits into 6 0 times, leaving a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Take the next digit (1) from the dividend and append it to 6, then repeat: 61 / 170

Step 2:
170 goes into 61 0 times with a remainder of 61.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 61 to get 61.
Grab the next digit (3) from the dividend, add it to 61, then carry on: 613 / 170

Let's proceed to step 3:
613 divided by 170 is 3 with a remainder of 103.
Put 3 as the next digit of the answer. 
Result so far: 3.0
The remainder is 103 after subtracting 510 from 613.
Bring next digit (8) of the dividend behind the 103 and repeat the process: 1038 / 170

Step 4:
170 can be fit into 1038 6 times, resulting in a remainder of 18.
Use 6 as the next digit of our solution. 
Result so far: 36.0
Deduct 1020 from 1038 and we're left with 18.
Fetch the next digit (8) from the dividend, attach it to 18 and continue: 188 / 170

On to step 5:
The number 170 fits into 188 1 times, leaving a remainder of 18.
Record the quotient 1 as the next digit in the result. 
Result so far: 361.0
Subtract 170 from 188 to get 18.
Grab the next digit (9) from the dividend, add it to 18, then carry on: 189 / 170

On to step 6:
When dividing 189 by 170, we get 1 with a remainder of 19.
Write down 1 as next digit of the result. 
Result so far: 3611.0
The remainder is 19 after subtracting 170 from 189.
Grab the next digit (0) from the dividend, add it to 19, then carry on: 190 / 170

Step 7:
170 can be fit into 190 1 times, resulting in a remainder of 20.
Record the quotient 1 as the next digit in the result. 
Result so far: 36111.0
The remainder is 20 after subtracting 170 from 190.
Append the next digit (0) from the dividend to 20 and continue with: 200 / 170

Step 8:
If we divide 200 by 170, we get 1 and a remainder of 30.
Write down 1 as next digit of the result. 
Result so far: 361111.0
The remainder is 30 after subtracting 170 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Let's proceed to step 9:
The number 170 fits into 300 1 times, leaving a remainder of 130.
The next digit of our result is 1. 
Result so far: 361111.1
If we take 170 away from 300, we end up with 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

Let's proceed to step 10:
170 goes into 1300 7 times with a remainder of 110.
The number 7 becomes the next digit in our result. 
Result so far: 361111.17
If we take 1190 away from 1300, we end up with 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1100, and continue the process.

Moving on to step 11:
The number 170 fits into 1100 6 times, leaving a remainder of 80.
The number 6 becomes the next digit in our result. 
Result so far: 361111.176
Subtract 1020 from 1100 to get 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Going ahead to step 12:
The number 170 fits into 800 4 times, leaving a remainder of 120.
Record the quotient 4 as the next digit in the result. 
Result so far: 361111.1764
The remainder is 120 after subtracting 680 from 800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Step 13:
170 can be fit into 1200 7 times, resulting in a remainder of 10.
The next digit of our result is 7. 
Result so far: 361111.17647
Subtracting 1190 from 1200 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Let's proceed to step 14:
If we divide 100 by 170, we get 0 and a remainder of 100.
Put 0 as the next digit of the answer. 
Result so far: 361111.17647
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.

Let's proceed to step 15:
The number 170 fits into 1000 5 times, leaving a remainder of 150.
Put 5 as the next digit of the answer. 
Result so far: 361111.1764705
The remainder is 150 after subtracting 850 from 1000.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

On to step 16:
When dividing 1500 by 170, we get 8 with a remainder of 140.
Record the quotient 8 as the next digit in the result. 
Result so far: 361111.17647058
If we subtract 1360 from 1500, we 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.

In conclusion, the division gives 361111.17647058 with a balance of 1.4e-07.
