85369890 ÷ 971 
Let's see how many times 971 fits into 85369890.

Moving on to step 1:
If we divide 8 by 971, we get 0 and a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Append the next digit (5) from the dividend to 8 and continue with: 85 / 971

Moving on to step 2:
971 goes into 85 0 times with a remainder of 85.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 85, we end up with 85.
Take the next digit (3) from the dividend and append it to 85, then repeat: 853 / 971

Going ahead to step 3:
853 divided by 971 is 0 with a remainder of 853.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 853, we get 853.
Bring next digit (6) of the dividend behind the 853 and repeat the process: 8536 / 971

Moving on to step 4:
When dividing 8536 by 971, we get 8 with a remainder of 768.
The number 8 becomes the next digit in our result. 
Result so far: 8.0
Deduct 7768 from 8536 and we're left with 768.
Append the next digit (9) from the dividend to 768 and continue with: 7689 / 971

Let's proceed to step 5:
If we divide 7689 by 971, we get 7 and a remainder of 892.
Write down 7 as next digit of the result. 
Result so far: 87.0
Subtract 6797 from 7689 to get 892.
Grab the next digit (8) from the dividend, add it to 892, then carry on: 8928 / 971

Let's proceed to step 6:
8928 divided by 971 is 9 with a remainder of 189.
Record the quotient 9 as the next digit in the result. 
Result so far: 879.0
If we subtract 8739 from 8928, we get 189.
Fetch the next digit (9) from the dividend, attach it to 189 and continue: 1899 / 971

Moving on to step 7:
971 goes into 1899 1 times with a remainder of 928.
The next digit of our result is 1. 
Result so far: 8791.0
Subtracting 971 from 1899 leaves us with 928.
Take the next digit (0) from the dividend and append it to 928, then repeat: 9280 / 971

On to step 8:
971 goes into 9280 9 times with a remainder of 541.
Record the quotient 9 as the next digit in the result. 
Result so far: 87919.0
Subtract 8739 from 9280 to get 541.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5410, and continue the process.

Going ahead to step 9:
The number 971 fits into 5410 5 times, leaving a remainder of 555.
Use 5 as the next digit of our solution. 
Result so far: 87919.5
The remainder is 555 after subtracting 4855 from 5410.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5550, and continue the process.

Advancing to step 10:
When dividing 5550 by 971, we get 5 with a remainder of 695.
Put 5 as the next digit of the answer. 
Result so far: 87919.55
Deduct 4855 from 5550 and we're left with 695.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6950, and continue the process.

The final outcome is 87919.55, with a leftover of 0.695.
